Netball is a ball sport played by two teams of seven players. Its development, derived from early versions of basketball, began in England in the 1890s. By 1960, international playing rules had been standardised for the game, the International Federation of Netball and Women's Basketball was formed; as of 2011, the INF comprises more than 60 national teams organized into five global regions. Games are played on a rectangular court with raised goal rings at each end; each team attempts to score goals by passing a ball down the court and shooting it through its goal ring. Players are assigned specific positions, which define their roles within the team and restrict their movement to certain areas of the court. During general play, a player with the ball can hold on to it for only three seconds before shooting for a goal or passing to another player; the winning team is the one. Netball games are 60 minutes long. Variations have been developed to increase the game's appeal to a wider audience. Netball is most popular in Commonwealth nations in schools, is predominantly played by women.
According to the INF, netball is played by more than 20 million people in more than 80 countries. Major domestic leagues in the sport include the Netball Superleague in Great Britain, Suncorp Super Netball in Australia and the ANZ Premiership in New Zealand. Four major competitions take place internationally: the quadrennial World Netball Championships, the Commonwealth Games, the yearly Quad Series and Fast5 Series. In 1995, netball became an International Olympic Committee recognised sport, but it has not been played at the Olympics. Netball emerged from early versions of basketball and evolved into its own sport as the number of women participating in sports increased. Basketball was invented in 1891 by James Naismith in the United States; the game was played indoors between two teams of nine players, using an association football, thrown into closed-end peach baskets. Naismith's game spread across the United States and variations of the rules soon emerged. Physical education instructor Senda Berenson developed modified rules for women in 1892.
Around this time separate intercollegiate rules were developed for women. The various basketball rules converged into a universal set in the United States. Martina Bergman-Österberg introduced a version of basketball in 1893 to her female students at the Physical Training College in Hampstead, London; the rules of the game were modified at the college over several years: the game moved outdoors and was played on grass. Österberg's new sport acquired the name "net ball". The first codified rules of netball were published in 1901 by the Ling Association the Physical Education Association of the United Kingdom. From England, netball spread to other countries in the British Empire. Variations of the rules and names for the sport arose in different areas: "women's basketball" arrived in Australia around 1900 and in New Zealand from 1906, while "netball" was being played in Jamaican schools by 1909. From the start, it was considered appropriate for women to play netball. Netball became a popular women's sport in countries where it was introduced and spread through school systems.
School leagues and domestic competitions emerged during the first half of the 20th century, in 1924 the first national governing body was established in New Zealand. International competition was hampered by a lack of funds and varying rules in different countries. Australia hosted New Zealand in the first international game of netball in Melbourne on 20 August 1938. Efforts began in 1957 to standardise netball rules globally: by 1960 international playing rules had been standardised, the International Federation of Netball and Women's Basketball the International Netball Federation, was formed to administer the sport worldwide. Representatives from England, New Zealand, South Africa, the West Indies were part of a 1960 meeting in Sri Lanka that standardised the rules for the game; the game spread to other African countries in the 1970s. South Africa was prohibited from competing internationally from 1969 to 1994 due to apartheid. In the United States, Netball's popularity increased during the 1970s in the New York area, the United States of America Netball Association was created in 1992.
The game became popular in the Pacific Island nations of the Cook Islands and Samoa during the 1970s. Netball Singapore was created in 1962, the Malaysian Netball Association was created in 1978. In Australia, the term women's basketball was used to refer to both basketball. During the 1950s and 1960s, a movement arose to change the Australian name of the game from women's basketball to netball in order to avoid confusion between the two sports; the Australian Basketball Union offered to pay the costs involved to alter the name, but the netball organisation rejected the change. In 1970, the Council of the All Australia Netball Association changed the name to "netball" in Australia. In 1963, the first international tournament was held in England. Called the World Tournament, it became known as the World Netball Championships. Following the first tournament, one of the organisers, Miss R. Harris, declared,England could learn
Czechoslovakia, or Czecho-Slovakia, was a sovereign state in Central Europe that existed from October 1918, when it declared its independence from the Austro-Hungarian Empire, until its peaceful dissolution into the Czech Republic and Slovakia on 1 January 1993. From 1939 to 1945, following its forced division and partial incorporation into Nazi Germany, the state did not de facto exist but its government-in-exile continued to operate. From 1948 to 1990, Czechoslovakia was part of the Eastern Bloc with a command economy, its economic status was formalized in membership of Comecon from 1949 and its defense status in the Warsaw Pact of May 1955. A period of political liberalization in 1968, known as the Prague Spring, was forcibly ended when the Soviet Union, assisted by several other Warsaw Pact countries, invaded. In 1989, as Marxist–Leninist governments and communism were ending all over Europe, Czechoslovaks peacefully deposed their government in the Velvet Revolution. In 1993, Czechoslovakia split into the two sovereign states of Slovakia.
Form of state1918 – 1938: A democratic republic championed by Tomáš Masaryk. 1938 – 1939: After annexation of Sudetenland by Nazi Germany in 1938, the region turned into a state with loosened connections among the Czech and Ruthenian parts. A large strip of southern Slovakia and Carpatho-Ukraine was annexed by Hungary, the Zaolzie region was annexed by Poland. 1939 – 1945: The region was split into the Protectorate of Bohemia and Moravia and the Slovak Republic. A government-in-exile continued to exist in London, supported by the United Kingdom, United States and their Allies. Czechoslovakia adhered to the Declaration by United Nations and was a founding member of the United Nations. 1946 – 1948: The country was governed by a coalition government with communist ministers, including the prime minister and the minister of interior. Carpathian Ruthenia was ceded to the Soviet Union. 1948 – 1989: The country became a socialist state under Soviet domination with a centrally planned economy. In 1960, the country became a socialist republic, the Czechoslovak Socialist Republic.
It was a satellite state of the Soviet Union. 1969 – 1990: The federal republic consisted of the Czech Socialist Republic and the Slovak Socialist Republic. 1990 – 1992: Following the Velvet Revolution, the state was renamed the Czech and Slovak Federal Republic, consisting of the Czech Republic and the Slovak Republic, reverted to a democratic republic.

The eastern region was composed of the northern reaches of the Carpathian Mountains and lands of the Danube River basin. ClimateThe weather is mild summers. Influenced by the Atlantic Ocean from the west, Baltic Sea from the north, Mediterranean Sea from the south. There is no continental weather. 1918–1920: Republic of Czechoslovakia /Czecho-Slovak State, or Czecho-Slovakia/Czechoslovakia 1920–1938: Czechoslovak Republic, or Czechoslovakia 1938–1939: Czecho-Slovak Republic, or Czecho-Slovakia 1945–1960: Czechoslovak Republic, or Czechoslovakia 1960–1990: Czechoslovak Socialist Republic, or Czechoslovakia April 1990: Czechoslovak Federative Republic and Czecho-Slovak Federative Republic The country subsequently became the Czech and Slovak Federative Republic, or Československo and Česko-Slovensko.
The area was long a part of the Austro-Hungarian Empire until the empire collapsed at the end of World War I. The new state was founded by Tomáš Garrigue Masaryk, who served as its first president from 14 November 1918 to 14 December 1935, he was succeeded by his close ally, Edvard Beneš. The roots of Czech nationalism go back to the 19th century, when philologists and educators, influenced by Romanticism, promoted the Czech language and pride in the Czech people. Nationalism became a mass movement in the second half of the 19th century. Taking advantage of the limited opportunities for participation in political life under Austrian rule, Czech leaders such as historian František Palacký founded many patriotic, self-help organizations which provided a chance for many of their compatriots to participate in communal life prior to independence. Palacký supported Austro-Slavism and worked for a reorganized and federal Austrian Empire, which would protect the Slavic speaking peoples of Central Europe against Russian and German threats.
An advocate of democratic reform and Czech autonomy within Austria-Hungary, Masaryk was elected twice to the Reichsrat, first from 1891 to 1893 for the Young Czech Party, again from 1907 to 1914 for the Czech Realist Party, which he had founded in 1889 with Karel Kramář and Josef Kaizl. During World War I small numbers of Czechs, the Czechoslovak Legions, fought with the Allies in France and Italy, while large numbers deserted to Russia in exchange for its support for the independence of Czechoslovakia from the Austrian Empire. With the outbreak of World War I, Masaryk began working for Czech independence in a union with Slovakia. With Edvard Beneš and Milan Rastislav Štefánik, Masaryk visited several Western countries and won support from influential publicists. Bohemia and Moravi
Korfball is a ball sport, with similarities to netball and basketball. It is played by two teams of four males in each team; the objective is to throw a ball into a bottomless basket, mounted on a 3.5 m high pole. The sport was invented by Dutch school teacher Nico Broekhuysen in 1902. In the Netherlands, there are over 90,000 people playing korfball; the sport is very popular in Belgium and Taiwan, is played in nearly 70 countries. In 1902 Nico Broekhuysen, a Dutch school teacher from Amsterdam, was sent to Nääs, a town in Sweden, to follow an educational course about teaching gymnastics to children; this is where he was introduced to the Swedish game'ringboll'. In ringboll one could score points by throwing the ball through a ring, attached to a 3 m pole. Men and women played together, the field was divided into three zones. Players could not leave their zone. Broekhuysen was inspired and when he returned to Amsterdam he decided to teach his students a similar game, he replaced the ring with a basket, so it was easier to see if a player had scored or not.
Broekhuysen simplified the rules so children could understand and play it. Korfball was born; the main idea was the same as ringboll. The oldest still existing korfball club to never have merged with any other club is a Dutch korfball club H. K. C. ALO from The Hague, Netherlands. H. K. C. ALO was founded on 1 February 1906. At first, there was considerable controversy about the sport, because the players were of both sexes. Several sports journalists refused to pay the slightest attention to the new sport. Korfball players were accused of being immoral; the sportswear was criticized, because the women were showing bare knees and ankles. Yet korfball was featured as a demonstration sport in the Summer Olympics of 1920 and 1928; the International Korfball Federation was founded in 1933 in Belgium. Korfball is played in 69 countries including: United States, England, Ireland, Australia, New Zealand, Czech Republic, Poland, Serbia, South Africa, India, The Netherlands, Nigeria, Ghana, Germany, Turkey, Hong Kong, Pakistan, Sweden, the Philippines, Italy, Spain and Romania.
It is growing in popularity in the UK and in a unique reference to the sport, is featured in a song by the band Half Man Half Biscuit entitled "Joy in Leeuwarden" on their 2011 album 90 Bisodol. Korfball has been played in the World Games since 1985. IKF World Korfball Championships have been held every four years since 1978; the leading nations are The Netherlands, Chinese Taipei, Belgium. Hong Kong hosted its first international tournament, the IKF Asia Oceania Korfball Championship in 2006. New Zealand hosted the IKF Asia Oceania Youth Korfball Championships in 2007. Korfball is played inside in winter and outdoors in autumn; the size of the indoor court is 20 m. The court is divided into halves called zones. In each zone is a 3.5 m tall post with a basket at the top. This is positioned two-thirds of the back of the zone. A korfball team consists of eight players. An international korfball match consists of four periods, with the length varying depending on the competition, but between 7 and 10 minutes, with a 1-minute break between period 1, 2, 3 and 4.
At half time - after period 2 - the break is 5 minutes. Four players of each team are in one zone and the other four are in the other zone. Within each zone, a player may only defend a member of the opposite team of the same gender. At the beginning of the match, one team chooses one-half of the court; that half will be their defending zone, with'their' basket in it. Players score by throwing the ball through the opponents' basket. After two goals, the teams change zones: defenders become attackers become defenders. In between those zone-changes, attackers can not set foot on their defending vice versa. At half-time teams swap halves; the rules prevent physical strength dominating the game. Blocking and holding are not allowed, as well as kicking the ball. Once a player has the ball, one cannot dribble, run or walk with it, one can move one foot as long as the foot the player landed on when they caught the ball stays in the same spot; therefore and efficient teamwork is required, because players need each other to keep the ball moving, throwing the ball to each other.
A player may not attempt to score when defended, which occurs when the defender is in between the opponent and the basket, is facing his/her opponent, is within arm's length and attempting to block the ball. This rule encourages fast movement while limiting the impact of players' height compared to their opponents; the national teams competition organized by the International World Games Association has been played every four years since 1981. The national teams competition organized by the International Korfball Federation has been played every four years since 1978. 2008 Kaohsiung, Taiwan – Winner: Netherlands 2012 Barcelona, Spain – Winner: Netherlands 2016 Olomouc, Czech Republic – Winner: Netherlands IKF promotes four continental championships: European Korfball Championship, All-Africa Korfball Championship, Pan-American Korfball Championship and Asia-Oceania Korfball Championship. Every year the IKF organises the Europ
A bicycle called a cycle or bike, is a human-powered or motor-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called bicyclist. Bicycles were introduced in the late 19th century in Europe, by the early 21st century, more than 1 billion were in existence at a given time; these numbers far exceed the number of cars, both in total and ranked by the number of individual models produced. They are the principal means of transportation in many regions, they provide a popular form of recreation, have been adapted for use as children's toys, general fitness and police applications, courier services, bicycle racing and bicycle stunts. The basic shape and configuration of a typical upright or "safety bicycle", has changed little since the first chain-driven model was developed around 1885. However, many details have been improved since the advent of modern materials and computer-aided design; these have allowed for a proliferation of specialized designs for many types of cycling.
The bicycle's invention has had an enormous effect on society, both in terms of culture and of advancing modern industrial methods. Several components that played a key role in the development of the automobile were invented for use in the bicycle, including ball bearings, pneumatic tires, chain-driven sprockets and tension-spoked wheels; the word bicycle first appeared in English print in The Daily News in 1868, to describe "Bysicles and trysicles" on the "Champs Elysées and Bois de Boulogne". The word was first used in 1847 in a French publication to describe an unidentified two-wheeled vehicle a carriage; the design of the bicycle was an advance on the velocipede, although the words were used with some degree of overlap for a time. Other words for bicycle include "bike", "pushbike", "pedal cycle", or "cycle". In Unicode, the code point for "bicycle" is 0x1F6B2; the entity 🚲. The "Dandy horse" called Draisienne or Laufmaschine, was the first human means of transport to use only two wheels in tandem and was invented by the German Baron Karl von Drais.
It is regarded as the modern bicycle's forerunner. Its rider sat astride a wooden frame supported by two in-line wheels and pushed the vehicle along with his or her feet while steering the front wheel; the first mechanically-propelled, two-wheeled vehicle may have been built by Kirkpatrick MacMillan, a Scottish blacksmith, in 1839, although the claim is disputed. He is associated with the first recorded instance of a cycling traffic offense, when a Glasgow newspaper in 1842 reported an accident in which an anonymous "gentleman from Dumfries-shire... bestride a velocipede... of ingenious design" knocked over a little girl in Glasgow and was fined five shillings. In the early 1860s, Frenchmen Pierre Michaux and Pierre Lallement took bicycle design in a new direction by adding a mechanical crank drive with pedals on an enlarged front wheel; this was the first in mass production. Another French inventor named Douglas Grasso had a failed prototype of Pierre Lallement's bicycle several years earlier.
Several inventions followed using rear-wheel drive, the best known being the rod-driven velocipede by Scotsman Thomas McCall in 1869. In that same year, bicycle wheels with wire spokes were patented by Eugène Meyer of Paris; the French vélocipède, made of iron and wood, developed into the "penny-farthing". It featured a tubular steel frame on; these bicycles were difficult to ride due to poor weight distribution. In 1868 Rowley Turner, a sales agent of the Coventry Sewing Machine Company, brought a Michaux cycle to Coventry, England, his uncle, Josiah Turner, business partner James Starley, used this as a basis for the'Coventry Model' in what became Britain's first cycle factory. The dwarf ordinary addressed some of these faults by reducing the front wheel diameter and setting the seat further back. This, in turn, required gearing—effected in a variety of ways—to efficiently use pedal power. Having to both pedal and steer via the front wheel remained a problem. Englishman J. K. Starley, J. H. Lawson, Shergold solved this problem by introducing the chain drive, connecting the frame-mounted cranks to the rear wheel.
These models were known as safety bicycles, dwarf safeties, or upright bicycles for their lower seat height and better weight distribution, although without pneumatic tires the ride of the smaller-wheeled bicycle would be much rougher than that of the larger-wheeled variety. Starley's 1885 Rover, manufactured in Coventry is described as the first recognizably modern bicycle. Soon the seat tube was added. Further innovations increased comfort and ushered in a second bicycle craze, the 1890s Golden Age of Bicycles. In 1888, Scotsman John Boyd Dunlop introduced the first practical pneumatic tire, which soon became universal. Willie Hume demonstrated the supremacy of Dunlop's tyres in 1889, winning the tyre's first-ever races in Ireland and England. Soon after, the rear freewheel was developed; this refinement led to the 1890s invention of coaster brakes. Dérailleur gears and hand-operated Bowden cable-pull brakes were developed during these years, but were only adopted by casual riders; the Svea Velocipede with vertical pedal arrangement and
Football is a family of team sports that involve, to varying degrees, kicking a ball to score a goal. Unqualified, the word football is understood to refer to whichever form of football is the most popular in the regional context in which the word appears. Sports called football in certain places include association football; these different variations of football are known as football codes. There are a number of references to traditional, ancient, or prehistoric ball games played by indigenous peoples in many different parts of the world. Contemporary codes of football can be traced back to the codification of these games at English public schools during the nineteenth century; the expansion of the British Empire allowed these rules of football to spread to areas of British influence outside the directly controlled Empire. By the end of the nineteenth century, distinct regional codes were developing: Gaelic football, for example, deliberately incorporated the rules of local traditional football games in order to maintain their heritage.
In 1888, The Football League was founded in England, becoming the first of many professional football competitions. During the twentieth century, several of the various kinds of football grew to become some of the most popular team sports in the world; the various codes of football share certain common elements and can be grouped into two main classes of football: carrying codes like American football, Canadian football, rugby union and rugby league, where the ball is moved about the field while being held in the hands or thrown, kicking codes such as Association football and Gaelic football, where the ball is moved with the feet, where handling is limited. Common rules among the sports include: Two teams of between 11 and 18 players. A defined area in which to play the game. Scoring goals or points by moving the ball to an opposing team's end of the field and either into a goal area, or over a line. Goals or points resulting from players putting the ball between two goalposts; the goal or line being defended by the opposing team.
Players being required to move the ball—depending on the code—by kicking, carrying, or hand-passing the ball. Players using only their body to move the ball. In all codes, common skills include passing, evasion of tackles and kicking. In most codes, there are rules restricting the movement of players offside, players scoring a goal must put the ball either under or over a crossbar between the goalposts. There are conflicting explanations of the origin of the word "football", it is assumed that the word "football" refers to the action of the foot kicking a ball. There is an alternative explanation, that football referred to a variety of games in medieval Europe, which were played on foot. There is no conclusive evidence for either explanation. A Chinese game called cuju has been recognised by FIFA as the first version of the game with regular rules, it existed during the Han dynasty and the Qin dynasty, in the second and third centuries BC. The Japanese version of cuju is kemari, was developed during the Asuka period.
This is known to have been played within the Japanese imperial court in Kyoto from about 600 AD. In kemari several people stand in a circle and kick a ball to each other, trying not to let the ball drop to the ground; the Ancient Greeks and Romans are known to have played many ball games, some of which involved the use of the feet. The Roman game harpastum is believed to have been adapted from a Greek team game known as "ἐπίσκυρος" or "φαινίνδα", mentioned by a Greek playwright and referred to by the Christian theologian Clement of Alexandria; these games appear to have resembled rugby football. The Roman politician Cicero describes the case of a man, killed whilst having a shave when a ball was kicked into a barber's shop. Roman ball games knew the air-filled ball, the follis. Episkyros is recognised as an early form of football by FIFA. There are a number of references to traditional, ancient, or prehistoric ball games, played by indigenous peoples in many different parts of the world. For example, in 1586, men from a ship commanded by an English explorer named John Davis, went ashore to play a form of football with Inuit people in Greenland.
There are accounts of an Inuit game played on ice, called Aqsaqtuk. Each match began with two teams facing each other in parallel lines, before attempting to kick the ball through each other team's line and at a goal. In 1610, William Strachey, a colonist at Jamestown, Virginia recorded a game played by Native Americans, called Pahsaheman. On the Australian continent several tribes of indigenous people played kicking and catching games with stuffed balls which have been generalised by historians as Marn Grook; the earliest historical account is an anecdote from the 1878 book by Robert Brough-Smyth, The Aborigines of Victoria, in which a man called Richard Thomas is quoted as saying, in about 1841 in Victoria, that he had witnessed Aboriginal people playing the game: "Mr Thomas describes how the foremost player will drop kick a ball made from the skin of a possum and how other players leap into the air in order to catch it." Some historians have theorised. The Māo
Russia the Russian Federation, is a transcontinental country in Eastern Europe and North Asia. At 17,125,200 square kilometres, Russia is by far or by a considerable margin the largest country in the world by area, covering more than one-eighth of the Earth's inhabited land area, the ninth most populous, with about 146.77 million people as of 2019, including Crimea. About 77 % of the population live in the European part of the country. Russia's capital, Moscow, is one of the largest cities in the world and the second largest city in Europe. Extending across the entirety of Northern Asia and much of Eastern Europe, Russia spans eleven time zones and incorporates a wide range of environments and landforms. From northwest to southeast, Russia shares land borders with Norway, Estonia, Latvia and Poland, Ukraine, Azerbaijan, China and North Korea, it shares maritime borders with Japan by the Sea of Okhotsk and the U. S. state of Alaska across the Bering Strait. However, Russia recognises two more countries that border it, Abkhazia and South Ossetia, both of which are internationally recognized as parts of Georgia.
The East Slavs emerged as a recognizable group in Europe between the 3rd and 8th centuries AD. Founded and ruled by a Varangian warrior elite and their descendants, the medieval state of Rus arose in the 9th century. In 988 it adopted Orthodox Christianity from the Byzantine Empire, beginning the synthesis of Byzantine and Slavic cultures that defined Russian culture for the next millennium. Rus' disintegrated into a number of smaller states; the Grand Duchy of Moscow reunified the surrounding Russian principalities and achieved independence from the Golden Horde. By the 18th century, the nation had expanded through conquest and exploration to become the Russian Empire, the third largest empire in history, stretching from Poland on the west to Alaska on the east. Following the Russian Revolution, the Russian Soviet Federative Socialist Republic became the largest and leading constituent of the Union of Soviet Socialist Republics, the world's first constitutionally socialist state; the Soviet Union played a decisive role in the Allied victory in World War II, emerged as a recognized superpower and rival to the United States during the Cold War.
The Soviet era saw some of the most significant technological achievements of the 20th century, including the world's first human-made satellite and the launching of the first humans in space. By the end of 1990, the Soviet Union had the world's second largest economy, largest standing military in the world and the largest stockpile of weapons of mass destruction. Following the dissolution of the Soviet Union in 1991, twelve independent republics emerged from the USSR: Russia, Belarus, Uzbekistan, Azerbaijan, Kyrgyzstan, Tajikistan and the Baltic states regained independence: Estonia, Lithuania, it is governed as a federal semi-presidential republic. Russia's economy ranks as the twelfth largest by nominal GDP and sixth largest by purchasing power parity in 2018. Russia's extensive mineral and energy resources are the largest such reserves in the world, making it one of the leading producers of oil and natural gas globally; the country is one of the five recognized nuclear weapons states and possesses the largest stockpile of weapons of mass destruction.
Russia is a great power as well as a regional power and has been characterised as a potential superpower. It is a permanent member of the United Nations Security Council and an active global partner of ASEAN, as well as a member of the Shanghai Cooperation Organisation, the G20, the Council of Europe, the Asia-Pacific Economic Cooperation, the Organization for Security and Co-operation in Europe, the World Trade Organization, as well as being the leading member of the Commonwealth of Independent States, the Collective Security Treaty Organization and one of the five members of the Eurasian Economic Union, along with Armenia, Belarus and Kyrgyzstan; the name Russia is derived from Rus', a medieval state populated by the East Slavs. However, this proper name became more prominent in the history, the country was called by its inhabitants "Русская Земля", which can be translated as "Russian Land" or "Land of Rus'". In order to distinguish this state from other states derived from it, it is denoted as Kievan Rus' by modern historiography.
The name Rus itself comes from the early medieval Rus' people, Swedish merchants and warriors who relocated from across the Baltic Sea and founded a state centered on Novgorod that became Kievan Rus. An old Latin version of the name Rus' was Ruthenia applied to the western and southern regions of Rus' that were adjacent to Catholic Europe; the current name of the country, Россия, comes from the Byzantine Greek designation of the Rus', Ρωσσία Rossía—spelled Ρωσία in Modern Greek. The standard way to refer to citizens of Russia is rossiyane in Russian. There are two Russian words which are commonly
Mixed-sex sports known as mixed-gender or coed sports, are sports where the participants are not of a single sex. This can take the form of team sports involving people of different sexes. In organised sports settings, rules dictate the number of people required of each sex in a team; such rules account for the sex differences in human physiology, with males being larger and stronger than females on average. In informal settings, mixed-sex sports involves groups of friends and/or family engaging in sport without regard to the sex of the participants. Sports which are mixed-sex as standard are ones where the differences between the sexes do not affect the ability of the competitor, for example equestrian sports. Sports in which the sex of a competitor affects their ability to compete have single-sex divisions, with mixed-team variants comprising the mixed-sex element of the sport, for example mixed doubles tennis. Mixed-sex sports have been encouraged as a way of boosting female sports participation and improving social harmony between the sexes.
Mixed-sex play and sports is common among young children, among whom differences are less pronounced. It is uncommon in most organised sports to find individuals of different genders competing head-to-head at elite level, principally due to the differences between the sexes. In sports where these differences are less linked to performance, it is standard practice for men and women to compete in mixed-sex fields; these open-class sports prove accommodating to intersex athletes, who challenge the sex-defined rules of both single-sex sport and mixed-sex sports with defined male and female roles. In equestrian sports and female riders compete against each other in eventing and show jumping disciplines. Female jockeys compete alongside male ones in horse racing, though the former constitute a minority of jockeys overall. Beyond the athletes, the horses used for racing are a mixed of male and female, with a 60/40 split at the top level between colts and fillies. In snooker, the professional tour is open to men and women, although only one woman has competed on the tour for a full year, although others have played in individual tournaments.
There is a separate women only tour to encourage female participation in the sport. During an Ultimate game, teams of 7 players play in direct competition with each other, while most people of the same gender mark each other, it is not uncommon to see match ups between people of different gender. A common form of mixed-sex sports involves pairs with one female team member. Sports based on dancing have male/female pairings, such as pair figure skating, ice dancing, ballroom dancing and synchronised swimming duets. In these sports the male and female participants physically work together to produce an artistic and athletic performance. Mixed doubles involves two mixed-sex pairs competing against each other with all four competitors in open play; this is prominent in racket sports, including tennis, table tennis, badminton and racquetball. Mixed pairs and mixed teams events are organised in contract bridge. Pairs may compete in turn-based games, where men and women take turns alternately; this is found in more strategy-based sports, including mixed doubles curling, mixed golf, mixed bowling and mixed team darts.
Separate male and female performances may be combined to produce mixed team results in such sports as diving. Synchronised diving is found in mixed-sex format. Mixed tag team matches are found in professional wrestling, where wrestlers are not explicitly competing in a turn-based manner, but are obliged to only face their opponent of the same sex. In non-vehicular racing sports the physiological differences between the sexes preclude head-to-head competition between people of different sexes at the elite level; as a result, mixed-sex events are most held with a relay race format. In running, a 4 × 400 metres mixed relay race was introduced at the 2017 IAAF World Relays, will be added to the 2019 World Championships in Athletics and 2020 Summer Olympics. In cross-country running, a 4 × 2 km mixed relay race was added at the 2017 IAAF World Cross Country Championships.
