Wheelchair
–
A wheelchair, often abbreviated to just chair, is a chair with wheels, used when walking is difficult or impossible due to illness, injury, or disability. Wheelchairs come in a variety of formats to meet the specific needs of their users. They may include specialized seating adaptions, individualized controls, and may be specific to particular activities, as seen with sports wheelchairs and beach wheelchairs. The earliest records of wheeled furniture are an inscription found on a slate in China. The first records of wheeled seats being used for transporting disabled people date to three centuries later in China, the Chinese used early wheelbarrows to move people as well as heavy objects. A distinction between the two functions was not made for several hundred years, around 525 CE, when images of wheeled chairs made specifically to carry people begin to occur in Chinese art. Later records show the use of technology in Europe by the Renaissance. The invalid carriage or Bath chair brought the technology into more common use from around 1760, in 1887, wheelchairs were introduced to Atlantic City so invalid tourists could rent them to enjoy the Boardwalk. Soon, many healthy tourists also rented the decorated rolling chairs and servants to them as a show of decadence. In 1933 Harry Jennings and his disabled friend Herbert Everest, both engineers, invented the first lightweight, steel, collapsible wheelchair. Everest had previously broken his back in a mining accident, Everest and Jennings saw the business potential of the invention and went on to become the first mass-market manufacturers of wheelchairs. Their x-brace design is still in use, albeit with updated materials. There are a variety of types of wheelchair, differing by propulsion method, mechanisms of control. Some wheelchairs are designed for everyday use, others for single activities. The iBot is perhaps the best known example of this in recent years, a self-propelled manual wheelchair incorporates a frame, seat, one or two footplates and four wheels, usually two caster wheels at the front and two large wheels at the back. There will generally also be a seat cushion. As this causes friction and heat build-up, particularly on long downslopes, everyday manual wheelchairs come in two major varieties, folding or rigid. Folding chairs are generally low-end designs, whose predominant advantage is being able to fold, however this is largely an advantage for part-time users who may need to store the wheelchair more often than use it

Track and field
–
Track and field is a sport which includes athletic contests established on the skills of running, jumping, and throwing. The name is derived from the sports venue, a stadium with an oval running track enclosing a grass field where the throwing and jumping events take place. Track and field is categorised under the sport of athletics, which also includes road running, cross country running. The foot racing events, which include sprints, middle- and long-distance events, the jumping and throwing events are won by the athlete who achieves the greatest distance or height. Regular jumping events include long jump, triple jump, high jump and pole vault, while the most common throwing events are shot put, javelin, discus and hammer. There are also combined events or multi events, such as the pentathlon consisting of five events, heptathlon consisting of seven events, in these, athletes participate in a combination of track and field events. Most track and field events are individual sports with a victor, the most prominent team events are relay races. Events are almost exclusively divided by gender, although both the mens and womens competitions are held at the same venue. It is one of the oldest sports, in ancient times, it was an event held in conjunction with festivals and sports meets such as the Ancient Olympic Games in Greece. The ancient Olympic Games began in the year 776 BC, when Koroibos, a cook from the city of Elis, won the stadium race. According to some traditions, this was the only athletic event of the games for the first 13 Olympic festivals. In modern times, the two most prestigious track and field competitions are athletics competition at the Olympic Games and the IAAF World Championships in Athletics. The International Association of Athletics Federations is the governing body. Records are kept of the best performances in specific events, at world and national levels, however, if athletes are deemed to have violated the events rules or regulations, they are disqualified from the competition and their marks are erased. In North America, the track and field may be used to refer to other athletics events, such as the marathon. The sport of track and field has its roots in human prehistory, Track and field-style events are among the oldest of all sporting competitions, as running, jumping and throwing are natural and universal forms of human physical expression. The first recorded examples of organized track and field events at a festival are the Ancient Olympic Games. At the first Games in 776 BC in Olympia, Greece, only one event was contested, Track and field events were also present at the Panhellenic Games in Greece around this period, and they spread to Rome in Italy around 200 BC

Summer Paralympic Games
–
The Summer Paralympic Games or the Games of the Paralympiad, are an international multi-sport event, where athletes with physical disabilities compete. This includes athletes with mobility disabilities, amputations, blindness, the Paralympic Games are held every four years, organized by the International Paralympic Committee. Medals are awarded in each event, with medals for first place, silver for second and bronze for third. The United States and the United Kingdom have each hosted two Summer Paralympic Games, more than any other nation. Other countries that have hosted the summer Paralympics are Australia, Canada, China, Greece, Israel, Italy, Japan, Netherlands, South Korea, Spain, in the 2016 Summer Paralympics, Brazil will host the first Summer Games in South America in Rio de Janeiro. Tokyo will be the first city to host the Summer Paralympics more than once,1964 and 2020. Seven of those countries have won at least one medal at every Summer Paralympic Games, Australia, Austria, France, Great Britain, Italy, Netherlands. The United States have been the nation for eight of the Paralympic Summer Games,1964,1968,1976,1980,1984,1988,1992 and 1996. China have been the nation for the four most recent Games,2004,2008,2012 and 2016. Italy, West Germany and Australia have been the nation one time each. Qualification rules for each of the Paralympic sports are set by the International Federation that governs that sports international competition, the first official Paralympic Games, was held in Rome in 1960. 400 athletes from 23 countries competed at the 1960 Games though only athletes in wheelchairs competed, at the 1976 Summer Games athletes with different disabilities were included for the first time at a summer Paralympics. With the inclusion of more disability classifications, the 1976 Summer Games expanded to 1,600 athletes from 40 countries, the 1988 Summer Paralympics were the first to be hosted in the same venues as the Olympics of that year. Since then, all Paralympic Games are now held in the city that hosted the Olympics. Each Paralympic sport then has its own classifications, dependent upon the physical demands of competition. Events are given a code, made of numbers and letters, describing the type of event, within the ten disability categories the athletes still need to be divided according to their level of impairment. The classification systems differ from sport to sport, and is intended to even the playing field so as to allow as many athletes to participate as possible, classifications vary in accordance with the different skills required to perform the sport. Archery, Archery is open to athletes with a physical disability, classifications are broken up into three divisions, W1, spinal cord injured and Cerebral Palsy athletes with impairment in all four limbs

Sport of athletics
–
Athletics is a collection of sporting events that involve competitive running, jumping, throwing, and walking. The most common types of competitions are track and field, road running, cross country running. The results of racing events are decided by finishing position, while the jumps, the simplicity of the competitions, and the lack of a need for expensive equipment, makes athletics one of the most commonly competed sports in the world. Athletics is mostly an individual sport, with the exception of relay races and competitions which combine athletes performances for a team score, organized athletics are traced back to the Ancient Olympic Games from 776 BCE. The rules and format of the events in athletics were defined in Western Europe and North America in the 19th and early 20th century. Most modern top level meetings are conducted by the International Association of Athletics Federations, the athletics meeting forms the backbone of the Summer Olympics. The foremost international athletics meeting is the IAAF World Championships in Athletics, other top level competitions in athletics include the IAAF World Cross Country Championships and the IAAF World Half Marathon Championships. Athletes with a disability compete at the Summer Paralympics and the IPC Athletics World Championships. The word athletics is derived from the Ancient Greek ἀθλητής from ἆθλον or ἆθλος, initially, the term was used to describe athletic contests in general – i. e. sporting competition based primarily on human physical feats. In the 19th century, the term acquired a more narrow definition in Europe. This definition continues to be the most prominent one in the United Kingdom, furthermore, foreign words in many German and Roman languages which are related to the term athletics also have a similar meaning. In much of North America, athletics is synonymous with sports in general, the word athletics is rarely used to refer to the sport of athletics in this region. Track and field is preferred, and is used in the United States and Canada to refer to most athletics events, including racewalking, Athletic contests in running, walking, jumping and throwing are among the oldest of all sports and their roots are prehistoric. Athletics events were depicted in the Ancient Egyptian tombs in Saqqara, with illustrations of running at the Heb Sed festival, the Tailteann Games were an ancient Celtic festival in Ireland, founded around 1800 BCE, and the thirty-day meeting included running and stone-throwing among its sporting events. The original and only event at the first Olympics in 776 BCE was a running event known as the stadion. This later expanded to include throwing and jumping events within the ancient pentathlon, Athletics competitions also took place at other Panhellenic Games, which were founded later around 500 BCE. The Cotswold Olimpick Games, a festival which emerged in 17th century England. Annually, from 1796 to 1798, LOlympiade de la République was held in revolutionary France, the premier event of this competition was a running event, but various ancient Greek disciplines were also on display

Paralympic athletics
–
Paralympic athletics is a disabled sport practiced by athletes with a physical disability who have competed at separate international events since 1952. It is governed by the International Paralympic Committee through its World Para Athletics subcommittee, rules for the sport are adapted from those set forth by the International Association of Athletics Federations. The majority of rules for Paralympic athletics are the same as those for able-bodied competitions, competitors at elite level competitions are classified by disability, to arrange athletes with a similar disability in the same event. A classified T12 athlete for example, is an athlete with a visual impairment. F = Field athletes T = Track athletes 11–13 – Visual impairment,20 – Intellectual disability 31–38 – Cerebral palsy 41–46 – Amputation, and others 51–58 – Wheelchair In wheelchair racing, athletes compete in lightweight racing chairs. Most major marathons have wheelchair divisions and the elite racers consistently beat the runners on foot, Paralympic athletes compete in the following events

Ludwig Guttmann
–
Sir Ludwig Poppa Guttmann CBE FRS was a German-born British neurologist who established the Paralympic Games in England. Ludwig Guttmann, the eldest child of the family, was born in Tost, within Upper Silesia and his family moved when he was three years old to the Silesia city of Königshütte. Guttman first encountered a patient with a spinal injury in 1917. The patient was a miner who later died of sepsis. Guttman started his studies in April 1918 at the University of Breslau. He transferred to the University of Freiburg in 1919 and received his Doctorate of Medicine in 1924, by 1933, Guttmann was considered the top neurosurgeon in Germany. Following the violent attacks on Jewish people and properties during Kristallnacht on 9 November 1938, the following day he justified his decision on a case-by-case basis with the Gestapo. Out of 64 admissions,60 patients were saved from arrest, in early 1939, Guttmann and his family left Germany because of the Nazi persecution of the Jews. An opportunity for escape arose when the Nazis provided him with a visa, Guttmann was scheduled to return to Germany via London, where the Council for Assisting Refugee Academics arranged for him to remain in the UK. He arrived with his wife Else Samuel Guttmann and two children, a son, Dennis and daughter, Eva aged 6 in Oxford, England, CARA, which negotiated with the British Home Office on their behalf, gave Guttmann and his family £250 to help settle in Oxford. Guttmann continued his spinal injury research at the Nuffield Department of Neurosurgery in the Radcliffe Infirmary, for the first few weeks after arrival the family resided in the Masters Lodge of Balliol College until they moved into a small semi-detached house in Lonsdale Road. Both children were offered places by the headmistress of Greycotes School. The family were members of the Oxford Jewish community, and Eva remembers becoming friendly with Miriam Margolyes, the Jewish community in Oxford was growing rapidly as a result of the influx of displaced academic Jews from Europe. With the outbreak of the Second World War, Guttmann and his family stayed in the home of Lord Lindsay, CARA Councillor, in September 1943 the British government asked Guttmann to establish the National Spinal Injuries Centre at Stoke Mandeville Hospital in Buckinghamshire. When the centre opened on 1 February 1944, Guttmann was appointed its director, Guttmann became a naturalised citizen of the United Kingdom in 1945. He organised the first Stoke Mandeville Games for disabled persons on 28 July 1948, Guttmann used the term paraplegic games for national games held in order to encourage his patients to take part. This came to be known as the Paralympics, which later became the Parallel Games. By 1952, more than 130 international competitors had entered the Stoke Mandeville Games, as the annual event continued to grow, the ethos and efforts by all those involved started to impress the organisers of the Olympic Games and members of the international community

Archery
–
Archery is the sport, practice or skill of using a bow to propel arrows. The word comes from the Latin arcus, historically, archery has been used for hunting and combat. In modern times, it is mainly a competitive sport and recreational activity, a person who participates in archery is typically called an archer or a bowman, and a person who is fond of or an expert at archery is sometimes called a toxophilite. The bow and arrow seems to have invented in the later Paleolithic or early Mesolithic periods. The oldest signs of its use in Europe come from the Stellmoor in the Ahrensburg valley north of Hamburg, Germany and dates from the late Paleolithic, about 10, 000–9000 BC. The arrows were made of pine and consisted of a mainshaft, there are no definite earlier bows, previous pointed shafts are known, but may have been launched by spear-throwers rather than bows. The oldest bows known so far come from the Holmegård swamp in Denmark, bows and arrows have been present in Egyptian culture since its predynastic origins. In the Levant, artifacts that could be arrow-shaft straighteners are known from the Natufian culture, the Khiamian and PPN A shouldered Khiam-points may well be arrowheads. Classical civilizations, notably the Assyrians, Greeks, Armenians, Persians, Parthians, Indians, Koreans, Chinese, akkadians were the first to use composite bows in war according to the victory stele of Naram-Sin of Akkad. The Welsh longbow proved its worth for the first time in Continental warfare at the Battle of Crécy, in the Americas archery was widespread at European contact. Archery was highly developed in Asia, the Sanskrit term for archery, dhanurveda, came to refer to martial arts in general. In East Asia, Goguryeo, one of the Three Kingdoms of Korea was well known for its regiments of skilled archers. Central Asian tribesmen and American Plains Indians became extremely adept at archery on horseback, lightly armoured, but highly mobile archers were excellently suited to warfare in the Central Asian steppes, and they formed a large part of armies that repeatedly conquered large areas of Eurasia. Shorter bows are more suited to use on horseback, and the bow enabled mounted archers to use powerful weapons. It is possible that barbarian peoples were responsible for introducing archery or certain types of bows to their civilized counterparts—the Xiong-nu, similarly, short bows seem to have been introduced to Japan by northeast Asian groups. The development of firearms rendered bows obsolete in warfare, albeit efforts were made to preserve archery practice. In Wales and England, for example, the government tried to practice with the Longbow until the end of the 16th century. This was because it was recognised that the bow had been instrumental to military success during the Hundred Years War, early firearms were inferior in rate-of-fire, and were very susceptible to wet weather

Bowls
–
Bowls or lawn bowls is a sport in which the objective is to roll biased balls so that they stop close to a smaller ball called a jack or kitty. It is played on a green which may be flat or convex or uneven. It is normally played outdoors and the surface is either natural grass, artificial turf. It has been traced certainly to the 13th century, and conjecturally to the 12th, the jactus lapidum of which he speaks may have been more akin to shotput. It is beyond dispute, however, that the game, at any rate in a form, was played in the 13th century. A manuscript of that period in the library, Windsor. The worlds oldest surviving bowling green is the Southampton Old Bowling Green, another manuscript of the same century has a crude but spirited picture which brings us into close touch with the existing game. Three figures are introduced and a jack, a 14th-century manuscript, Book of Prayers, in the Francis Douce collection in the Bodleian Library at Oxford contains a drawing in which two persons are shown, but they bowl to no mark. Strutt suggests that the first players bowl may have been regarded by the player as a species of jack. In the third he stands almost upright, in the first he kneels, in the second he stoops, the game eventually came under the ban of king and parliament, both fearing it might jeopardise the practice of archery, then so important in battle. Statutes forbidding it and other sports were enacted in the reigns of Edward III, Richard II, even when, on the invention of gunpowder and firearms, the bow had fallen into disuse as a weapon of war, the prohibition was continued. The word bowls occurs for the first time in the statute of 1511 in which Henry VIII confirmed previous enactments against unlawful games and it was further enjoined that any one playing bowls outside his own garden or orchard was liable to a penalty of 6s. While those possessed of lands of the value of £100 might obtain licences to play on their own private greens. Young Mitchell was only 11 when he played on Kilmarnock Bowling green and this is turn led to the codification of modern rules for many sports, including lawn bowls, most football codes, lawn tennis and others. National Bowling Associations were established in the late 1800s, today the sport is played in over 40 countries with more than 50 member national authorities. The home of the game is still Scotland with the World Bowls centre in Edinburgh at Caledonia House,1 Redheughs Rigg, South Gyle, Edinburgh. Lawn bowls is played on a large, rectangular, precisely levelled and manicured grass or synthetic surface known as a bowling green which is divided into parallel playing strips called rinks. Once it has come to rest, the jack is aligned to the centre of the rink, a bowl may curve outside the rink boundary on its path, but must come to rest within the rink boundary to remain in play

Table tennis
–
Table tennis, also known as ping pong, is a sport in which two or four players hit a lightweight ball back and forth across a table using a small bat. The game takes place on a hard table divided by a net, a point is scored when a player fails to return the ball within the rules. Play is fast and demands quick reactions, spinning the ball alters its trajectory and limits an opponents options, giving the hitter a great advantage. Table tennis is governed by the worldwide organization International Table Tennis Federation, ITTF currently includes 220 member associations. The table tennis rules are specified in the ITTF handbook. Table tennis has been an Olympic sport since 1988, with several event categories, from 1988 until 2004, these were mens singles, womens singles, mens doubles and womens doubles. Since 2008, an event has been played instead of the doubles. The sport originated in Victorian England, where it was played among the upper-class as a parlour game. It has been suggested that makeshift versions of the game were developed by British military officers in India in around 1860s or 1870s, who brought it back with them. A row of books stood up along the center of the table as a net and it had several different names, including whiff-whaff. The name ping-pong was in use before British manufacturer J. Jaques & Son Ltd trademarked it in 1901. The name ping-pong then came to describe the game played using the rather expensive Jaquess equipment, a similar situation arose in the United States, where Jaques sold the rights to the ping-pong name to Parker Brothers. Parker Brothers then enforced its trademark for the term in the 1920s making the various associations change their names to table tennis instead of the more common, but trademarked, term. The next major innovation was by James W. Gibb, a British enthusiast of table tennis, who discovered novelty celluloid balls on a trip to the US in 1901 and found them to be ideal for the game. This was followed by E. C. Goode who, in 1901, invented the modern version of the racket by fixing a sheet of pimpled, or stippled, rubber to the wooden blade. Table tennis was growing in popularity by 1901 to the extent that tournaments were being organized, books being written on the subject, in 1921, the Table Tennis Association was founded in Britain, and the International Table Tennis Federation followed in 1926. London hosted the first official World Championships in 1926, in 1933, the United States Table Tennis Association, now called USA Table Tennis, was formed. In the 1930s, Edgar Snow commented in Red Star Over China that the Communist forces in the Chinese Civil War had a passion for the English game of table tennis which he found bizarre

Shot put
–
The shot put is a track and field event involving throwing/putting a heavy spherical object —the shot—as far as possible. The shot put competition for men has been a part of the modern Olympics since their revival in 1896, homer mentions competitions of rock throwing by soldiers during the Siege of Troy but there is no record of any dead weights being thrown in Greek competitions. The first evidence for stone- or weight-throwing events were in the Scottish Highlands, in the 16th century King Henry VIII was noted for his prowess in court competitions of weight and hammer throwing. The first events resembling the modern shot put likely occurred in the Middle Ages when soldiers held competitions in which they hurled cannonballs, shot put competitions were first recorded in early 19th century Scotland, and were a part of the British Amateur Championships beginning in 1866. Competitors take their throw from inside a marked circle 2.135 metres in diameter, the following rules are adhered to for a legal throw, Upon calling the athletes name, the athlete may enter from any part of the throwing circle. They have sixty seconds to commence the throwing motion otherwise they are banned from the game, the athlete may not wear gloves, IAAF rules permit the taping of individual fingers. The athlete must rest the shot close to the neck, the shot must be released above the height of the shoulder, using only one hand. The athlete may touch the surface of the circle or toe board. Limbs may however extend over the lines of the circle in the air, the shot must land in the legal sector of the throwing area. The athlete must leave the circle from the back. The athlete may enter the circle at the location of their choice. Foul throws occur when an athlete, Does not pause within the circle before beginning the throwing motion, does not complete the throwing movement within sixty seconds of having their name called. Allows the shot to drop below his shoulder or outside the plane of his shoulder during the put. At any time if the shot loses contact with the neck then it is technically an illegal throw, during the throwing motion, touches with any part of the body, the top or ends of the toe board the top of the iron ring anywhere outside the circle. Throws a shot which either falls outside the sector or touches a sector line on the initial impact. Leaves the circle before the shot has landed, does not leave from the rear half of the circle. The following are either obsolete or non-existent, but commonly believed rules within professional competition, the athlete entering the circle, then exiting and re-entering it prior to starting the throw results in a foul. Each competition has a set number of rounds of throws, typically there are three preliminary rounds to determine qualification for the final, and then three more rounds in the final

Javelin throw
–
The javelin throw is a track and field event where the javelin, a spear about 2.5 m in length, is thrown. The javelin thrower gains momentum by running within a predetermined area, Javelin throwing is an event of both the mens decathlon and the womens heptathlon. The javelin was part of the pentathlon of the Ancient Olympic Games beginning in 708 BC in two disciplines, distance and target throw, the javelin was thrown with the aid of a thong, called ankyle wound around the middle of the shaft. Athletes would hold the javelin by the thong and when the javelin was released this thong unwound giving the javelin a spiraled flight, throwing javelin-like poles into targets was revived in Germany and Sweden in the early 1870s. In Sweden, these developed into the modern javelin, and throwing them for distance became a common event there. The rules continued to evolve over the decades, originally, javelins were thrown with no run-up. Limited run-ups were introduced in the late 1890s, and soon developed into the modern unlimited run-up, swedens Eric Lemming, who threw his first world best in 1899 and ruled the event from 1902 to 1912, was the first dominant javelin thrower. Competitions for the hand only were less common, though not unknown. At the Olympics a both-hands contest was only once, in 1912, Finland swept the medals. Hungarys Mór Kóczán used a freestyle end grip to break the 60-meter barrier in 1911, the first known womens javelin marks were recorded in Finland in 1909. Originally, women threw the same implement as men, a lighter, shorter javelin for women was introduced in the 1920s, womens javelin throw was added to the Olympic program in 1932, Mildred Babe Didrikson of the United States became the first champion. For a long time, javelins were made of wood, typically birch. The current mens record is held by Jan Železný at 98.48 m. Of the 69 Olympic medals that have been awarded in the javelin,32 have gone to competitors from Norway. Finland has, however, never been nearly as successful in the womens javelin, the javelin was also part of some of the many early forms of womens pentathlon, and has always been included in the heptathlon after it replaced the pentathlon in 1981. The size, shape, minimum weight, and center of gravity of the javelin are all defined by IAAF rules. In international competition, men throw a javelin between 2.6 and 2.7 m in length and 800 g in weight, the javelin has a grip, about 150 mm wide, made of cord and located at the javelins center of gravity. Unlike the other throwing events, the used to throw the javelin is dictated by IAAF rules

Club throw
–
The club throw is an athletic throwing event where the object is to throw a wooden club. The event is one of the four throwing events, along with discus, javelin and it is the Paralympic equivalent of the hammer throw. The club throw was introduced for men and women at the first Summer Paralympic Games in 1960. It was dropped from the programme from the 1992 Paralympics in Barcelona but was reinstated for London 2012. The club for men and women weighs a minimum of 397 grams and is made from wood with a metal base. The athlete sits in a frame in an area which is within a marked circle between 2.135 and 2.50 metres in diameter. The frame is common for each competitor and is rigid, the sport is contested at the Paralympics by athletes in the F31, F32 and F51 classes. As of 2015 the world record for the club in the 32 class is held by Vladislav Frolov. The mens record in the 51 class is held by Zeljko Dimitrijevic, as of 2015 the world record for the womens club in the 32 class is held by Maroua Ibrahmi, who threw 24.15 metres in Lyon, France on 24 July 2013. The womens record in the 51 class is held by Americas Rachael Morrison, Athletics at the Summer Paralympics Disability sport classification

Wheelchair basketball
–
Wheelchair basketball is basketball played by people with varying physical disabilities that disqualify them from playing an able-bodied sport. These include spina bifida, birth defects, cerebral palsy, paralysis due to accident, amputations, the International Wheelchair Basketball Federation is the governing body for this sport. It is recognized by the International Paralympic Committee as the competent authority in wheelchair basketball worldwide. FIBA has recognized IWBF under Article 53 of its General Statutes, the IWBF has 82 National Organizations for Wheelchair Basketball actively participating in wheelchair basketball throughout the world, with this number increasing each year. It is estimated more than 100,000 people play wheelchair basketball from recreation to club play. Wheelchair basketball is played by boys, girls, men and women, Wheelchair basketball is included in the Paralympic Games. The Wheelchair Basketball World Championship is played two years after every Paralympic Games, major competition in wheelchair basketball comes from Canada, Australia, the United States, Great Britain, the Netherlands, and Japan. In 1944, Ludwig Guttmann, through the program at the Stoke Mandeville Hospital, in Aylesbury, Buckinghamshire, England. It was known as wheelchair netball, at around the same times, starting from 1946, wheelchair basketball games were played primarily between American World War II disabled veterans. This began in the United States at the University of Illinois, dr. Timothy Nugent founded the National Wheelchair Basketball Association in 1949 and served as Commissioner for the first 25 years. The Stoke Mandeville Wheelchair Games, held in 1947, were the first games to be held and included only a handful of participants, growth in both the number of wheelchair events and participants came quickly. Wheelchair netball was introduced in the 1948 Games, in 1952, a team from the Netherlands was invited to compete with the British team. This became the first International Stoke-Mandeville Games, an event that has been held ever since. Wheelchair basketball, as we know it now, was first played at the 1956 International Stoke-Mandeville Games, the US Pan Am Jets team won the tournament. In 1973, the International Stoke Mandeville Games Federation established the first sub-section for wheelchair basketball, at that time ISMGF was the world governing body for all wheelchair sports. In 1989 ISMGF accepted for its former wheelchair basketball sub-section to be named International Wheelchair Basketball Federation, full independence came in 1993 with the IWBF becoming the world body for wheelchair basketball with full responsibility for development of the sport. World championships for the sport have been held since 1973, with Bruges, the first world championship for men was won by Great Britain. Of the first 11 mens world championships, six were won by the United States, Canada has won four of the womens world championship titles, and the United States two

Marathon
–
The marathon is a long-distance running race with an official distance of 42.195 kilometres, usually run as a road race. The event was instituted in commemoration of the run of the Greek soldier Pheidippides, a messenger from the Battle of Marathon to Athens. The marathon was one of the original modern Olympic events in 1896, more than 800 marathons are held throughout the world each year, with the vast majority of competitors being recreational athletes as larger marathons can have tens of thousands of participants. The name Marathon comes from the legend of Philippides or Pheidippides and it is said that he ran the entire distance without stopping and burst into the assembly, exclaiming νενικήκαμεν, before collapsing and dying. Lucian of Samosata also gives the story, but names the runner Philippides, there is debate about the historical accuracy of this legend. In some Herodotus manuscripts, the name of the runner between Athens and Sparta is given as Philippides, in 1879, Robert Browning wrote the poem Pheidippides. Brownings poem, his story, became part of late 19th century popular culture and was accepted as a historic legend. This route, as it existed when the Olympics were revived in 1896, was approximately 40 kilometres long, and this route is considerably shorter, some 35 kilometres, but includes a very steep initial climb of more than 5 kilometres. When the modern Olympics began in 1896, the initiators and organizers were looking for a great popularizing event, the idea of a marathon race came from Michel Bréal, who wanted the event to feature in the first modern Olympic Games in 1896 in Athens. This idea was supported by Pierre de Coubertin, the founder of the modern Olympics. The Greeks staged a race for the Olympic marathon on 10 March 1896 that was won by Charilaos Vasilakos in 3 hours and 18 minutes. The winner of the first Olympic marathon, on 10 April 1896, was Spyridon Louis, the marathon of the 2004 Summer Olympics was run on the traditional route from Marathon to Athens, ending at Panathinaiko Stadium, the venue for the 1896 Summer Olympics. The womens marathon was introduced at the 1984 Summer Olympics and was won by Joan Benoit of the United States with a time of 2 hours 24 minutes and 52 seconds. It has become a tradition for the mens Olympic marathon to be the last event of the athletics calendar, often, the mens marathon medals are awarded during the closing ceremony. The Olympic mens record is 2,06,32, set at the 2008 Summer Olympics by Samuel Kamau Wanjiru of Kenya, the Olympic womens record is 2,23,07, set at the 2012 Summer Olympics by Tiki Gelana of Ethiopia. The mens London 2012 Summer Olympic marathon winner was Stephen Kiprotich of Uganda, per capita, the Kalenjin ethnic group of Rift Valley Province in Kenya has produced a highly disproportionate share of marathon and track-and-field winners. Johnny Hayes victory at the 1908 Summer Olympics contributed to the growth of long-distance running and marathoning in the United States. Later that year, races around the season including the Empire City Marathon held on New Years Day 1909 in Yonkers, New York

Para-athletics classification
–
Para-athletics classification at the Paralympic Games is the basis for determining who can compete in specific athletic sports, and within which class. Classification is handled by the International Paralympic Committee, with classification spelled in the IPC Athletics Classification Handbook, people with physical, vision and intellectual disabilities are eligible to compete in this sport. The classification for this sport was created during the 1940s and for much of its history was a medical condition based classification system. The classification system has become a functional mobility based one. Para-athletics classification at the Paralympic Games is the basis for determining who can compete in athletic sports. It is used for the purposes of establishing fair competition, the general rules for para-athletics are based on rules intended for able-bodied competitors. The blind classifications are based on classification, not functional classification. This plays a significant role in athletics races, Classification is handled by the International Paralympic Committee, with classification spelled in the IPC Athletics Classification Handbook. While CP-ISRA has an interest in the sport because it is open to people with cerebral palsy, in 1983, the rules for this sport and approval for classification was done by the International Amateur Athletics Federation. At the 1992 Games, athletics classification was governed by four different sporting bodies including the IBSA, ISOD, ISMWSF, as of 2012, people with physical, vision and intellectual disabilities are eligible to compete in this sport. The classification for this sport was created during the 1940s and for much of its history was a medical condition based classification system. An example of classification in this period was L2 SCI, which was for competitors who had normal functioning except for lower limb paralysis. These competitors would not compete in races against double above the knee amputees because, while their functional disabilities were similar. The first wheelchair races took place by 1952 at the Stoke Mandeville Hospital, in 1964, the International Sport Organization for the Disabled was created. They created the first formal system, which had 27 classes. This was reduced to 12 classes for the 1976 Summer Paralympics and was reduced to nine classes for the 1992 Summer Paralympics. There were too few people in a classification to the point where an event for people with disabilities said 1000 competitors =1000 winners. There were some exceptions to this in classes like double leg paralysis as a result of brain or spinal injury, in 1983, classification for cerebral palsy competitors in this sport was done by the Cerebral Palsy International Sports and Recreation Association

Bicycle tire
–
A bicycle tire is a tire that fits on the wheel of a bicycle, unicycle, tricycle, quadracycle, bicycle trailer, or trailer bike. They may also be used on wheelchairs and handcycles, especially for racing, Bicycle tires provide an important source of suspension, generate the lateral forces necessary for balancing and turning, and generate the longitudinal forces necessary for propulsion and braking. They are the second largest source, after air drag, of consumption on a level road. The modern detachable pneumatic bicycle tire contributed to the popularity and eventual dominance of the safety bicycle, the first bicycle tires were iron bands on the wooden wheels of velocipedes. These were followed by rubber tires on penny-farthings. The first patent for rubberized wheels was granted to Clément Ader in 1868, in an attempt to soften the ride, rubber tires with a hollow core were also tried. The first practical pneumatic tire was made by John Boyd Dunlop in 1887 for his sons bicycle, Dunlop is credited with realizing rubber could withstand the wear and tear of being a tire while retaining its resilience. This led to the founding of Dunlop Pneumatic Tyre Co, by 1890, it began adding a tough canvas layer to the rubber to reduce punctures. Racers quickly adopted the pneumatic tire for the increase in speed it enabled, finally, the detachable tire was introduced in 1891 by Édouard Michelin. It was held on the rim with clamps, instead of glue, three main techniques for attaching a bicycle tire to a rim have been developed, clincher, wired and tubular. Clinchers originally did not have wire in the beads and the shape of the bead interlocked with a flange on the rim, however, this type of tire is no longer in general use and the term clincher has transferred to the modern wired-on tire. For the remainder of this article, the use of the word clincher will be assumed. In an attempt to provide the best attributes of both wired and tubular methods, tubular clinchers have also been offered, most bicycle tires are clincher for use with clincher rims. These tires have a wire or Kevlar fiber bead that interlocks with flanges in the rim. A separate airtight inner tube enclosed by the rim supports the tire carcass, an advantage of this system is that the inner tube can be easily accessed in the case of a leak to be patched or replaced. The ISO 5775-2 standard defines designations for bicycle rims and it distinguishes between Straight-side rims Crochet-type rims Hooked-bead rims Traditional wired-on rims were straight-sided. Various hook designs re-emerged in the 1970s to hold the bead of the tire in place and this allows higher air pressures than older wired-on tires. In these designs, it is the interlocking of the bead with the rim, not the tight fit or resistance to stretching of the bead, some tires are torus-shaped and attached to tubular rims with adhesive

Handcycle
–
A handcycle is a type of human-powered land vehicle powered by the arms rather than the legs, as on a bicycle. Most handcycles are tricycle in form, with two coasting rear wheels and one steerable powered front wheel, despite usually having three wheels, they are also known as handbikes. Many manufacturers have designed and released hand-powered recumbent trikes, or handcycles, Handcycles are a regular sight at HPV meets and are beginning to be seen on the streets. They commonly follow a design with front wheels driven by standard derailleur gearing powered by hand cranks. Brake levers are mounted on the handholds which are usually mounted in phase, unlike pedal cranks. This allows the rider to easily use their torso to help propel the cycle. The entire crank assembly and the front wheel turn together, allowing the rider to steer, some designs use two front wheels and a single rear wheel, while others use lean-steer designs. A handcycle is not a wheelchair, handcycle has a crank and gears, Handcycles come in a variety of styles, making them accessible to people with a wide variety of disabilities. There are also hybrids between a handcycle, a recumbent bike and a tricycle, fork steer handcycles represent the majority of handcycles sold. Manufacturers of this type of handcycle include Invacare, Intrepid Equipment, Varna, Schmicking, riders turn lean steer handcycles by leaning into the turn. There is a learning curve with lean steer handcycles and they are significantly less stable at high speed. The lean steer system feels similar to skiing, using your whole body to steer the handcycle. Lean steer handcycles can work well for lower-level injuries, although, manufacturers of this type of handcycle include Lighting Handcycles and Brike International Ltd. The off road is different from other handcycles in that there are two wheels in front and one behind, and it has a gear ratio range. This gives the cycle the ability to tackle steep slopes and permits handcycle mountain biking, the addition of a wider tire with suitable tread makes some mountain biking possible on standard road bikes. Handcycles have also used for touring, and to better accommodate this interest, some manufacturers incorporate mudguards. As handcycles have evolved they have become lighter, and they have better gearing for long climbs

International Standard Book Number
–
The International Standard Book Number is a unique numeric commercial book identifier. An ISBN is assigned to each edition and variation of a book, for example, an e-book, a paperback and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, the method of assigning an ISBN is nation-based and varies from country to country, often depending on how large the publishing industry is within a country. The initial ISBN configuration of recognition was generated in 1967 based upon the 9-digit Standard Book Numbering created in 1966, the 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108. Occasionally, a book may appear without a printed ISBN if it is printed privately or the author does not follow the usual ISBN procedure, however, this can be rectified later. Another identifier, the International Standard Serial Number, identifies periodical publications such as magazines, the ISBN configuration of recognition was generated in 1967 in the United Kingdom by David Whitaker and in 1968 in the US by Emery Koltay. The 10-digit ISBN format was developed by the International Organization for Standardization and was published in 1970 as international standard ISO2108, the United Kingdom continued to use the 9-digit SBN code until 1974. The ISO on-line facility only refers back to 1978, an SBN may be converted to an ISBN by prefixing the digit 0. For example, the edition of Mr. J. G. Reeder Returns, published by Hodder in 1965, has SBN340013818 -340 indicating the publisher,01381 their serial number. This can be converted to ISBN 0-340-01381-8, the check digit does not need to be re-calculated, since 1 January 2007, ISBNs have contained 13 digits, a format that is compatible with Bookland European Article Number EAN-13s. An ISBN is assigned to each edition and variation of a book, for example, an ebook, a paperback, and a hardcover edition of the same book would each have a different ISBN. The ISBN is 13 digits long if assigned on or after 1 January 2007, a 13-digit ISBN can be separated into its parts, and when this is done it is customary to separate the parts with hyphens or spaces. Separating the parts of a 10-digit ISBN is also done with either hyphens or spaces, figuring out how to correctly separate a given ISBN number is complicated, because most of the parts do not use a fixed number of digits. ISBN issuance is country-specific, in that ISBNs are issued by the ISBN registration agency that is responsible for country or territory regardless of the publication language. Some ISBN registration agencies are based in national libraries or within ministries of culture, in other cases, the ISBN registration service is provided by organisations such as bibliographic data providers that are not government funded. In Canada, ISBNs are issued at no cost with the purpose of encouraging Canadian culture. In the United Kingdom, United States, and some countries, where the service is provided by non-government-funded organisations. Australia, ISBNs are issued by the library services agency Thorpe-Bowker

Cross country running
–
Cross country running is a sport in which teams and individuals run a race on open-air courses over natural terrain such as dirt or grass. Sometimes the runners are referred to as harriers, the course, typically 4–12 kilometres long, may include surfaces of grass, and earth, pass through woodlands and open country, and include hills, flat ground and sometimes gravel road. It is both an individual and a sport, runners are judged on individual times and teams by a points-scoring method. Cross country running is one of the disciplines under the sport of athletics. Although open-air running competitions are pre-historic, the rules and traditions of cross country racing emerged in Britain, the English championship became the first national competition in 1876 and the International Cross Country Championships was held for the first time in 1903. Since 1973 the foremost elite competition has been the IAAF World Cross Country Championships, Cross country courses are laid out on an open or woodland area. The IAAF recommends that courses be grass-covered, and have rolling terrain with frequent, courses consist of one or more loops, with a long straight at the start and another leading to the finish line. Because of variations in conditions, international standardization of cross country courses is impossible, part of cross country runnings appeal is the natural and distinct characteristics of each venues terrain and weather. Terrain can vary from open fields to forest hills and even across rivers and it also includes running down and up hills. According to the IAAF, a cross country course has a loop of 1,750 to 2,000 metres laid out on an open or wooded land. It should be covered by grass, as much as possible, while it is perfectly acceptable for local conditions to make dirt or snow the primary surface, courses should minimize running on roads or other macadamized paths. Parks and golf courses often provide suitable locations, a course at least 5 metres full allows competitors to pass others during the race. Clear markings keep competitors from making wrong turns, and spectators from interfering with the competition, markings may include tape or ribbon on both sides of the course, chalk or paint on the ground, or cones. Some classes use colored flags to indicate directions, red flags for left turns, yellow flags for right turns, courses also commonly include distance markings, usually at each kilometer or each mile. The course should have 400 to 1,200 m of level terrain before the first turn, to reduce contact, however, many courses at smaller competitions have their first turn after a much shorter distance. Courses for international competitions consist of a loop between 1750 and 2000 meters, athletes complete three to six loops, depending on the race. Senior men compete on a 12-kilometre course, senior women and junior men compete on an 8-kilometre course. Junior women compete on a 6-kilometre course, in the United States, college men typically compete on 8 km or 10 km courses, while college women race for 5 km or 6 km

Road running
–
Road running is the sport of running on a measured course over an established road. These events are classified as long-distance according to athletics terminology. They may involve large numbers of runners or wheelchair entrants, the three most common IAAF recognized distances for road running events are 10K runs, half marathons and marathons. Despite this, there are far more 5K road race events, due to their popularity for charity races and similar, less competitive reasons to hold an event. Road running may offer those involved a range of challenges and interests such as dealing with hills, sharp bends, varied surfaces, inclement weather, aerobic fitness, or the ability of the body to use oxygen, is the biggest factor contributing to success. The impact of running on roads puts more stress on the feet, knees and it can compensate by providing a consistent, level surface. It may put less strain on the Achilles tendon, before engaging in road running, one should choose a shoe that best suits ones foot type and running style. Road running is one of forms of road racing, which also include road bicycle racing. Race courses are held on the streets of major cities and towns. Other common distances include 5 kilometres,8 kilometres,12 kilometres, some major events have unique distances. Most road race courses are certified to be accurate to within 0. 1%, certified courses are often intentionally lengthened by one metre per km to ensure that they are not short of the stated distance. A Jones Counter attached to a bicycle is used to course length. Remeasurement to verify the length is undertaken when a record is set on a course. Running that covers a distance farther than a marathon is called ultrarunning, such events can be measured in distance or by time. Beyond the ultramarathon lie the multiday and stage races, Road running is unique among athletic events because in many cases first time amateurs are welcome to participate in the same event as members of running clubs and even current world-class champions. Sometimes race times are recorded manually by race organizers, most road races feature electronic timing using transponders, Road races are often community-wide events that highlight or raise money for an issue or project. In the USA, Susan G. Komens Race for the Cure is held nationwide to raise breast cancer awareness and this race is also run in Germany, Italy and Puerto Rico. Similarly, Race for Life holds races throughout the UK to raise money for Cancer Research UK, first person race reports frequently appear on the Dead Runners Society electronic mailing list

Racewalking
–
Racewalking, or race walking, is a long-distance discipline within the sport of athletics. Although it is a race, it is different from running in that one foot must appear to be in contact with the ground at all times. This is assessed by race judges, typically held on either roads or on running tracks, common distances vary from 3000 metres up to 100 kilometres. There are two racewalking distances contested at the Summer Olympics, the 20 kilometres race walk and 50 kilometres race walk, both are held as road events. The biennial IAAF World Championships in Athletics also features the three events. The IAAF World Indoor Championships featured 5000 m and 3000 m race walk variations, top level athletics championships and games typically feature 20 km racewalking events. Compared to other forms of racing, stride length is reduced. There are two rules that govern racewalking, the first dictates that the athletes back toe cannot leave the ground until the heel of the front foot has touched. Violation of this rule is known as loss of contact, the second rule requires that the supporting leg must straighten from the point of contact with the ground and remain straightened until the body passes directly over it. These rules are judged by the human eye. Athletes regularly lose contact for a few milliseconds per stride, which can be caught on film, athletes stay low to the ground by keeping their arms pumping low, close to their hips. If one sees a racewalkers shoulders rising, it may be a sign that the athlete is losing contact with the ground, what appears to be an exaggerated swivel to the hip is, in fact, a full rotation of the pelvis. Athletes aim to move the forward, and to minimize sideways motion in order to achieve maximum forward propulsion. Speed is achieved by stepping quickly with the aim of rapid turnover and this minimizes the risk of the feet leaving the ground. Strides are short and quick, with pushoff coming forward from the ball of the foot, world-class racewalkers can average under four and five minutes per kilometre in a 20-km racewalk. Races have been walked at distances as short as 3 kilometres —at the 1920 Summer Olympics—and as long as 100 km. The mens world record for the 50-mile race walk is held by Israeli Shaul Ladany, the modern Olympic events are the 20 km race walk and 50 km race walk. There are judges on the course to monitor form, three judges submitting red cards for violations results in disqualification

Sprint (running)
–
Sprinting is running over a short distance in a limited period of time. It is used in sports that incorporate running, typically as a way of quickly reaching a target or goal. In athletics and track and field, sprints are races over short distances and they are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, there are three sprinting events which are currently held at the Summer Olympics and outdoor World Championships, the 100 metres,200 metres, and 400 metres. The set position differs depending on the start, body alignment is of key importance in producing the optimal amount of force. Ideally the athlete should begin in a 4-point stance and push off using both legs for maximum force production, athletes remain in the same lane on the running track throughout all sprinting events, with the sole exception of the 400 m indoors. Races up to 100 m are largely focused upon acceleration to a maximum speed. All sprints beyond this distance increasingly incorporate an element of endurance, the 60 metres is a khaled and Rion indoor event and it is an indoor world championship event. Less common events include the 50 metres,55 metres,300 metres, biological factors that determine a sprinters potential include, The 60 metres is normally run indoors, on a straight section of an indoor athletic track. Since races at this distance can last around six or seven seconds, having good reflexes and this is roughly the distance required for a human to reach maximum speed and can be run with one breath. It is popular for training and testing in other sports, the world record in this event is held by American sprinter Maurice Greene with a time of 6.39 seconds. 60-metres is used as a distance by younger athletes when starting sprint racing. Note, Indoor distances are less standardized as many facilities run shorter or occasionally longer distances depending on available space, the 100 metres sprint takes place on one length of the home straight of a standard outdoor 400 m track. Often, the holder in this race is considered the worlds fastest man/woman. The current world record of 9.58 seconds is held by Usain Bolt of Jamaica and was set on 16 August 2009, the womens world record is 10.49 seconds and was set by Florence Griffith-Joyner. World class male sprinters need 41 to 50 strides to cover the whole 100 metres distances, the 200 metres begins on the curve of a standard track, and ends on the home straight. The ability to run a good bend is key at the distance, as a well conditioned runner will typically be able to run 200 m in an average speed higher than their 100 m speed. Usain Bolt, however, ran 200 m in the time of 19.19 sec, an average speed of 10.422 m/s, whereas he ran 100 m in the world-record time of 9.58 sec

60 metres
–
60 metres is a sprint event in track and field athletics. It is an event for indoor championships, normally dominated by the best outdoor 100 metres runners. At outdoor venues it is a distance, at least for senior athletes. The 60 metres was an Olympic event in the 1900 and 1904 Summer Games but was removed from the schedule thereafter. American Maurice Greene currently holds the world record in the 60 metres with a time of 6.39. In the past, it was common for athletes to compete in the 60 yards race and this is not part of the lineage of the 60 metres, but is the predecessor of the 55 metres race.

100 metres
–
The 100 metres, or 100-metre dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, it is one of the most popular and it has been contested at the Summer Olympics since 1896 for men and since 1928 for women. The reigning 100 m Olympic champion is named the fastest runner in the world. The World Championships 100 metres has been contested since 1983, jamaicans Usain Bolt and Shelly-Ann Fraser-Pryce are the reigning world champions, Bolt and Elaine Thompson are the Olympic champions in the mens and womens 100 metres, respectively. On an outdoor 400 metres running track, the 100 m is run on the home straight, runners begin in the starting blocks and the race begins when an official fires the starters pistol. Sprinters typically reach top speed after somewhere between 50–60 m and their speed then slows towards the finish line. The 10-second barrier has historically been a barometer of fast mens performances, the current mens world record is 9.58 seconds, set by Jamaicas Usain Bolt in 2009, while the womens world record of 10.49 seconds set by American Florence Griffith-Joyner in 1988 remains unbroken. The 100 m emerged from the metrication of the 100 yards, the event is largely held outdoors as few indoor facilities have a 100 m straight. US athletes have won the mens Olympic 100 metres title more times than any country,16 out of the 28 times that it has been run. US women have dominated the event winning 9 out of 21 times. At the start, some athletes play psychological games such as trying to be last to the starting blocks, at high level meets, the time between the gun and first kick against the starting block is measured electronically, via sensors built in the gun and the blocks. A reaction time less than 0.1 s is considered a false start, the 0. 2-second interval accounts for the sum of the time it takes for the sound of the starters pistol to reach the runners ears, and the time they take to react to it. For many years a sprinter was disqualified if responsible for two false starts individually, however, this rule allowed some major races to be restarted so many times that the sprinters started to lose focus. The next iteration of the rule, introduced in February 2003, meant that one false start was allowed among the field, but anyone responsible for a subsequent false start was disqualified. To avoid such abuse and to improve spectator enjoyment, the IAAF implemented a change in the 2010 season – a false starting athlete now receives immediate disqualification. This proposal was met with objections when first raised in 2005, justin Gatlin commented, Just a flinch or a leg cramp could cost you a years worth of work. The rule had an impact at the 2011 World Championships. Runners normally reach their top speed just past the point of the race

150 metres
–
150 metres is a sprint event in track and field. It is a very rarely contested non-championship and not an IAAF-recognised event, the event was given a high-profile outing in 1997 as an intermediate contest between two 1996 Olympic champions, Donovan Bailey and Michael Johnson. Johnson pulled up mid-race, allowing Bailey to win the $1 million prize.35 seconds, Allyson Felix ran the fastest ever 150 m race by a woman in 2013, although faster times have been recorded at intermediate stages of the 200 m event. The Great North City Games features a similar setup to the Manchester event and has provided several of the best mens and womens times. The British events typically attracted American, British and Caribbean competitors, a one-off 150 m race on Copacabana Beach in Rio de Janeiro was held in 2013 and Bolt finished in a time close to his own world record. The 150 m had some significance as an indoor event in the 1960s and 1970s as a result of indoor tracks matching that distance. Wales held a championship over the distance up to 1972. A relay version of the distance was contested at the 1967 European Athletics Indoor Championships and was won by the Soviet Unions womens team. Italy also provided a womens 150 m best that same decade, marlon Devonish also ran 14.88 straight. Any performance with a wind of more than 2.0 metres per second is not counted for record purposes. Below is a list of the fastest wind-assisted times, only times that are superior to legal bests are shown. Linford Christie ran 14.74 s on 23 July 1995 in Sheffield Donovan Bailey ran 14.92 s on 23 July 1995 in Sheffield, below is a list of other times equal or superior to 16.94, Allyson Felix also ran 16.36 straight.

200 metres
–
The 200 metres is a sprint running event. On an outdoor 400 m track, the race begins on the curve and ends on the home straight, a slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes rely on different energy systems during the longer sprint, in the United States and elsewhere, athletes previously ran the 220-yard dash instead of the 200 m, though the distance is now obsolete. The standard adjustment used for the conversion from times recorded over 220 yards to 200 m times is to subtract 0.1 seconds, another obsolete version of this race is the 200 metres straight, which was run on tracks that contained such a straight. Initially, when the International Amateur Athletic Association started to ratify world records in 1912, in 1951, the IAAF started to recognise records set on a curved track. In 1976, the record was discarded. The race attracts runners from other events, primarily the 100 metres, wishing to double up, marion Jones finished first in both races in 2000 but was later disqualified and stripped of her medals after admitting to taking performance-enhancing drugs. An Olympic double of 200 m and 400 m was first achieved by Valerie Brisco-Hooks in 1984, Usain Bolt is the only man to repeat as Olympic champion, Bärbel Wöckel and Veronica Campbell-Brown are the two women who have repeated as Olympic champion. The mens world record holder is Usain Bolt of Jamaica, who ran 19. 19s at the 2009 World Championships, the womens world record holder is Florence Griffith-Joyner of the United States, who ran 21. 34s at the 1988 Summer Olympics. The reigning Olympic champions are Usain Bolt and Elaine Thompson, the reigning World Champions are Bolt and Dafne Schippers.

400 metres
–
The 400 metres, or 400 metre dash, is a common sprinting event in track and field competitions. It has been featured in the programme at the Summer Olympics since 1896 for men. On a standard running track, it is one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes competed in the 440 yard dash —which is a quarter of a mile and was referred to as the quarter-mile—instead of the 400 m. An athlete who competes in the 400 m may still be referred to as quarter-miler, while considered to be predominantly an anaerobic event, there is some aerobic involvement and the degree of aerobic training required for 400 metre athletes is open to debate. The current mens record is held by Wayde van Niekerk, with a time of 43.03 seconds, van Niekerk is also the reigning world. The world indoor record holder is Kerron Clement, in 44.57 seconds, the current womens world record is held by Marita Koch, with a time of 47.60 seconds. Allyson Felix is the womens world champion, while Shaunae Miller holds the womens Olympic title. The mens T43 Paralympic world record of 45.07 seconds is held by Oscar Pistorius. An Olympic double of 200 metres and 400 m was first achieved by Valerie Brisco-Hooks in 1984, alberto Juantorena of Cuba at the 1976 Summer Olympics became the first and so far the only athlete to win both the 400 m and 800 m Olympic titles. The Olympic champion has won a second gold medal in the 4 ×400 metres relay. From 31 appearances in the Olympic Games, the gold medallist came from the USA19 times.

Hurdling
–
Hurdling is the act of running and jumping over an obstacle at speed. In the early 19th century, hurdlers ran at and jumped over each hurdle, after experimenting with different step patterns the 3-step for high hurdles, 7-step for low hurdles, and 15-step for intermediate hurdles was decided on. In the sport of athletics, hurdling forms the basis of a number track, in these events, a series of barriers known as hurdles are set at precisely measured heights and distances which each athlete must pass by running over. Failure to pass over, by passing under, or intentionally knocking over hurdles will result in disqualification, accidental knocking over of hurdles is not cause for disqualification, but the hurdles are weighted to make doing so disadvantageous. Hurdle design improvements were made in 1935, when they developed the L-shaped hurdle, with this shape, the athlete could hit the hurdle and it will tip down, clearing the athletes path. The two shorter distances take place on the straight of a track, while the 400 m version covers one whole lap of a standard oval track. Events over shorter distances are commonly held at indoor track and field events. Women historically competed in the 80 meters hurdles at the Olympics in the mid-20th century, hurdles race are also part of combined events contests, including the decathlon and heptathlon. In track races, hurdles are normally between 68–107 cm in height, and vary depending on the age and gender of the hurdler, events from 50 to 110 meters are technically known as high hurdles races, while longer competitions are low hurdles races. The track hurdles events are forms of sprinting competitions, although the 400 m version is less anaerobic in nature, a hurdling technique can also be found in the steeplechase, although in this event athletes are also permitted to step on the barrier to clear it. Similarly, in cross country running athletes may hurdle over various natural obstacles, such as logs, mounds of earth, horse racing has its own variant of hurdle racing, with similar principles. The standard sprint or short hurdle race is 110 meters for men and 100 meters for women, the standard amount of steps to the first hurdle should be 8. The standard long hurdle race is 400 meters for men and women. Each of these races is run over ten hurdles and they are all Olympic events, the mens 200 meters low hurdles event was on the Olympic athletics programme for the 1900 and 1904 Summer Olympics. These low hurdles events were widely participated in the part of the 20th century. However, beyond these two Olympic outings, they never gained a consistent place at international competitions and became increasing rare after the 1960s and this 10-hurdle race continues to be run in places such as Norway. Other distances are run, particularly indoors but occasionally outdoors, the sprint hurdle race indoors is usually 60 meters for both men and women, although races 55 meters or 50 meters long are sometimes run, especially in the United States. A60 meter indoor race is run over 5 hurdles, a shorter race may occasionally have only 4 hurdles

100 metres hurdles
–
The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women. For the race, ten hurdles of a height of 83.8 centimetres are placed along a course of 100 metres. The first hurdle is placed after a run-up of 13 metres from the starting line. The next 9 hurdles are set at a distance of 8.5 metres from each other, the hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous. Fallen hurdles do not count against runners provided that they do not run them on purpose. Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks, the fastest 100 m hurdlers run the distance in a time of around 12.5 seconds. The world record set by Kendra Harrison stands at 12.20 seconds, the Olympic Games had included the 80 m hurdles in the program from 1932 to 1968. Starting with the 1972 Summer Olympics the womens race was lengthened to 100 m hurdles, the hurdles sprint race has been run by women since the beginning of womens athletics, just after the end of World War I. The distances and hurdle heights varied widely in the beginning, while the men had zeroed in on the 110 m hurdles, the International Womens Sport Federation had registered records for eight different disciplines by 1926. At the first Womens World Games in 1922 a 100 m hurdles race was run, from 1926 until 1968 on only the 80 m distance was run. For the 80 m race women had to clear eight hurdles placed at a distance of 8 metres from each other and a height of 76.2 cm. Just like with the races, until 1935 no more than three hurdles could be knocked over and records were only officially registered if the runner had cleared all her hurdles clean. In 1935, this rule was abandoned, and L-shaped hurdles were introduced that fell over forward easily and greatly reduced the risk of injury to the runner. Hurdles are weighted, so when properly set for the height, the 80 m hurdles was on the list of womens sports demanded by the International Womens Sport Federation for the Olympic Summer Games in 1928, but wasnt included as an Olympic discipline until 1932. Starting with 1949 the 80 m hurdles was one of the disciplines included in the womens pentathlon, during the 1960s some experimental races were run over a distance of 100 metres using hurdles with a height of 76.2 cm. The modern 100 m race has an extra 2 hurdles compared to the 80 m race, the home stretch is shorter by 1.5 m. A version of the 100 metres hurdles is also used for 50- to 59-year-old men in Masters athletics and they run the same spacing as women, which coordinates with existing markings on most tracks, but run over 36-inch hurdles. In the 60-69 age range, the spacings are changed, women over age 40, men over age 70 run 80 metre versions with different heights and spacings

110 metres hurdles
–
The 110 metres hurdles, or 110-meter hurdles, is a hurdling track and field event for men. It is included in the programme at the Summer Olympic Games. The female counterpart is the 100 metres hurdles, as part of a racing event, ten hurdles of 1.067 metres in height are evenly spaced along a straight course of 110 metres. They are positioned so that they fall over if bumped into by the runner. Fallen hurdles do not carry a time penalty for the runners. Like the 100 metres sprint, the 110 metres hurdles begins in the starting blocks and it is occasionally referred to as the 110 meter high hurdles, to distinguish it from events at other distances that use lower hurdles. For the 110 m hurdles, the first hurdle is placed after a run-up of 13.72 metres from the starting line. The next nine hurdles are set at a distance of 9.14 metres from each other, the Olympic Games have included the 110 metre hurdles in their program since 1896. The equivalent hurdles race for women was run over a course of 80 metres from 1932 to 1968, starting with the 1972 Summer Olympics, the womens race was set at 100 metres. In the early 20th century, the race was contested as 120 yard hurdles. The fastest 110 metre hurdlers run the distance in around 13 seconds, Aries Merritt of the United States holds the current world record of 12.80 seconds, set at the Memorial Van Damme meet on 7 September 2012 in Belgium. For the first hurdles races in England around 1830, wooden barriers were placed along a stretch of 100 yards. The first standards were attempted in 1864 in Oxford and Cambridge, The length of the course was set to 120 yards and over its course, the height and spacing of the hurdles have been related to Imperial units ever since. After the length of the course was rounded up to 110 metres in France in 1888, the massively constructed hurdles of the early days were first replaced in 1895 with somewhat lighter T-shaped hurdles that runners were able to knock over. However, until 1935 runners were disqualified if they knocked down more than three hurdles, and records were only recognized if the runner had left all hurdles standing. In 1935 the T-shaped hurdles were replaced by L-shaped ones that easily fall forward if bumped into, however those hurdles are weighted so it is disadvantageous to hit them. The 110 metre hurdles have been an Olympic discipline since 1896, women ran it occasionally in the 1920s but it never became generally accepted. From 1926 on, women have only run the 80 metre hurdles which was increased to 100 metres starting in 1961 on a trial basis and in 1969 in official competition

400 metres hurdles

The 400 metres hurdles is a track and field hurdling event. The event has been on the Olympic athletics programme since 1900 for men, on a standard outdoor track,400 metres is the length of the inside lane, once around the stadium. Runners stay in their lanes the entire way after starting out of the blocks, the hurdles are positioned and weighted so that they fall forward if bumped into with sufficient force, to prevent injury to the runners. Although there is no longer any penalty for knocking hurdles over, runners prefer to clear them cleanly, the best male athletes can run the 400 m hurdles in a time of around 47 seconds, while the best female athletes achieve a time of around 53 seconds. The current mens and womens world record holders are Kevin Young with 46.78 seconds, compared to the 400 metres run, the hurdles race takes the men about three seconds longer and the women four seconds longer. The 400 m hurdles was held for both sexes at the inaugural IAAF World Championships in Athletics, the first championship for women came at the 1980 World Championships in Athletics – being held as a one-off due to the lack of a race at the 1980 Summer Olympics. The first awards in a 400 m hurdles race were given in 1860 when a race was held in Oxford, England, while running the course, participants had to clear twelve wooden hurdles, over 100 centimetres tall, that had been spaced in even intervals. To reduce the risk of injury, somewhat more lightweight constructions were introduced in 1895 that runners could push over, the 400 m hurdles became an Olympic event at the 1900 Summer Olympics in Paris, France. At the same time, the race was standardized so that virtually identical races could be held, as a result, the official distance was fixed to 400 metres, or one lap of the stadium, and the number of hurdles was reduced to ten. The official height of the hurdles was set to 91.4 cm for men and 76.20 cm for women, the first documented 400 m hurdles race for women took place in 1971. Many athletic commentators and officials have often brought up the idea of lifting the height of the womens 400 m hurdles to incorporate a greater requirement of hurdling skill. This was the case at the World Championships in Seville and the problem can often be seen at international and national meetings. The 400m hurdle race one of the most demanding of all events in the sprint-hurdle group and it requires speed, endurance, and hurdling technique all along with unique awareness and special concentration throughout the race. When preparing to hurdle, the blocks should be set so that the athlete arrives at the first hurdle leading on the desired leg without inserting a stutter step. A stutter step is when the runner has to chop his or her stride down to arrive on the leg for take off. At the beginning of the take-off, the knee must be driven toward the hurdle, the knee should be slightly bent when crossing the hurdle. Unless an athlete’s body has great flexibility, the knee must be bent to allow a forward body lean. Unlike the 110m hurdles, a significant forward body lean is not that necessary due to the hurdles being lower, however, the trail leg must be kept bent and short to provide a quick lever action allowing a fast hurdle clearance

800 metres

The 800 metres, or 800 meters, is a common track running event. It is the shortest common middle-distance running event, the 800 metres is run over two laps of the track and has been an Olympic event since the first games in 1896. During indoor track season the event is run on a 200-metre track. The event was derived from the measurement of a half a mile. Imperial racing distances were common in the United States, american high schools were the last to convert to metric distances in 1980, following the NCAAs conversion in 1976. Countries associated to the English system converted to metric distances after the 1966 Commonwealth Games,800 m is 4.67 m less than half a mile. The event combines aerobic endurance with anaerobic conditioning and sprint speed, both the aerobic and anaerobic systems are being taxed to a high extent, thus the 800 metre athlete is required to combine training between both systems. If they are so inclined,400 m runners are encouraged to run the 200 metres while 800 m runners are encouraged to run the 1500 metres. The 800 m event is known for its tactical racing techniques. Because the 800 m event is the shortest event that has all the runners converge on lane one and it is commonly believed that getting the first or second position early in the race is advantageous as these positions are not usually caught up in the pack. Olympic champions Dave Wottle, Yuriy Borzakovskiy and others have defied that logic by running a more evenly paced race, lagging behind the pack and kicking past the slowing early leaders. Often the winner of 800 m races at high levels are not determined by the strongest runner and this can lead to the most exciting aspect of the 800 m which is its high probability of an upset. Two common tactics for the 800 meters are running a split or a positive split between laps. The positive split is widely considered to be the more effective strategy, a positive split is achieved by running the first lap faster than the second lap, and a negative split is achieved by the opposite, running the second lap faster than the first. The current world record holder, David Rudisha, runs using a positive split strategy, in his 2012 Olympic race, he ran his first lap in 49.28 seconds and his second lap in 51.63 seconds. Theoretically, a split is the most effective strategy. As of August 2016 As of August 2016, World junior records are held by Nijel Amos and Pamela Jelimo. Both marks coincidentally rank them as the third fastest ever, a Known as the World Indoor Games IAAF list of 800-metres records in XML
