Olympic-style weightlifting, or Olympic weightlifting simply referred to as weightlifting, is an athletic discipline in the modern Olympic programme in which the athlete attempts a maximum-weight single lift of a barbell loaded with weight plates. The two competition lifts in order are the clean and jerk; the snatch is a one-move lift. The clean and jerk is a two-move lift; each weightlifter receives three attempts in each, the combined total of the highest two successful lifts determines the overall result within a bodyweight category. Bodyweight categories are different for female competitors. A lifter who fails to complete at least one successful snatch and one successful clean and jerk fails to total, therefore receives an "incomplete" entry for the competition; the clean and press was once a competition lift, but was discontinued due to difficulties in judging proper form. In comparison with other strength sports, which test limit strength, weightlifting tests aspects of human ballistic limits.
While there are few competitive Olympic weightlifters, the lifts performed in the sport of weightlifting, in particular their component lifts, are used by elite athletes in other sports to train for both explosive and functional strength. The sport is controlled by the International Weightlifting Federation. Based in Budapest, it was founded in 1905. Athletes compete in a division determined by their body mass. In Summer of 2018, the IWF approved the current weight categories, specifying which 7 of the 10 total would be contested at the Olympics. Men's weight classes: IWF Categories 55 kg 61 kg 67 kg 73 kg 81 kg 89 kg 96 kg 102 kg 109 kg 109 kg and over Olympic Categories 61 kg 67 kg 73 kg 81 kg 96 kg 109 kg 109 kg and over Women's weight classes: IWF Categories 45 kg 49 kg 55 kg 59 kg 64 kg 71 kg 76 kg 81 kg 87 kg 87 kg and over Olympic Categories 49 kg 55 kg 59 kg 64 kg 76 kg 87 kg 87 kg and over In each weight division, lifters compete in both the snatch and clean and jerk. Prizes are given for the heaviest weights lifted in each and in the overall—the maximum lifts of both combined.
The order of the competition is up to the lifters—the competitor who chooses to attempt the lowest weight goes first. If they are unsuccessful at that weight, they have the option of reattempting at that weight or trying a heavier weight after any other competitors have made attempts at the previous weight or any other intermediate weights; the barbell is loaded incrementally and progresses to a heavier weight throughout the course of competition. Weights are set in 1 kilogram increments. If two athletes lift the same weight, they are both credited with it but in terms of placing the one who listed the weight first gets the highest placing. During competition, the snatch event takes place first, followed by a short intermission, the clean and jerk event. There are two side judges and one head referee who together provide a "successful" or "failed" result for each attempt based on their observation of the lift within the governing body's rules and regulations. Two successes are required for any attempt to pass.
The judges' and referee's results are registered via a lighting system with a white light indicating a "successful" lift and a red light indicating a "failed" lift. This is done for the benefit of all in attendance be they athlete, administrator or audience. In addition, one or two technical officials may be present to advise during a ruling. At local competitions, a "Best Lifter" title is awarded, it is awarded to women's lifters. The award is based on a formula which employs the "Sinclair Coefficient", a coefficient derived and approved by the sport's world governing body and which allows for differences in both gender and bodyweight; when the formula is applied to each lifter's overall total and grouped along with the other competitors' and evaluated, it provides a numeric result which determines the competition's best overall men's and women's lifters. And while the winner of the heaviest weight class will have lifted the most overall weight during the course of a competition, a lifter in a lighter weight class may still have lifted more weight both relative to their own bodyweight, to the Sinclair coefficient formula, thereby garnering the "Best Lifter" award.
Competition to establish who can lift the heaviest weight has been recorded throughout civilization, with the earliest known recordings including those found in Egypt and ancient Greece. Today, the modern sport of weightlifting traces its origins to the European competitions of the 19th century; the first male world champion was crowned in 1891. The first Olympic Games of 1896 included weightlifting in the Field event of the predecessor to today's track and field or athletics event. During the 1900 Olympic Games, there was no weightlifting event. Weightlifting resumed as an event, again in athletics, in 1904 but was omitted from the Games of 1908 and 1912; these were the last Games until after the First World War. In these early Games, a distinction was drawn between lifting with'one hand' only and lifting with't
Basketball is a team sport in which two teams, most of five players each, opposing one another on a rectangular court, compete with the primary objective of shooting a basketball through the defender's hoop while preventing the opposing team from shooting through their own hoop. A field goal is worth two points, unless made from behind the three-point line, when it is worth three. After a foul, timed play stops and the player fouled or designated to shoot a technical foul is given one or more one-point free throws; the team with the most points at the end of the game wins, but if regulation play expires with the score tied, an additional period of play is mandated. Players advance the ball by bouncing it while walking or running or by passing it to a teammate, both of which require considerable skill. On offense, players may use a variety of shots -- a dunk, it is a violation to lift or drag one's pivot foot without dribbling the ball, to carry it, or to hold the ball with both hands resume dribbling.
The five players on each side at a time fall into five playing positions: the tallest player is the center, the tallest and strongest is the power forward, a shorter but more agile big man is the small forward, the shortest players or the best ball handlers are the shooting guard and the point guard, who implements the coach's game plan by managing the execution of offensive and defensive plays. Informally, players may play three-on-three, two-on-two, one-on-one. Invented in 1891 by Canadian-American gym teacher James Naismith in Springfield, United States, basketball has evolved to become one of the world's most popular and viewed sports; the National Basketball Association is the most significant professional basketball league in the world in terms of popularity, salaries and level of competition. Outside North America, the top clubs from national leagues qualify to continental championships such as the Euroleague and FIBA Americas League; the FIBA Basketball World Cup and Men's Olympic Basketball Tournament are the major international events of the sport and attract top national teams from around the world.
Each continent hosts regional competitions for national teams, like FIBA AmeriCup. The FIBA Women's Basketball World Cup and Women's Olympic Basketball Tournament feature top national teams from continental championships; the main North American league is the WNBA, whereas strongest European clubs participate in the EuroLeague Women. In early December 1891, Canadian James Naismith, a physical education professor and instructor at the International Young Men's Christian Association Training School in Springfield, was trying to keep his gym class active on a rainy day, he sought a vigorous indoor game to keep his students occupied and at proper levels of fitness during the long New England winters. After rejecting other ideas as either too rough or poorly suited to walled-in gymnasiums, he wrote the basic rules and nailed a peach basket onto a 10-foot elevated track. In contrast with modern basketball nets, this peach basket retained its bottom, balls had to be retrieved manually after each "basket" or point scored.
Basketball was played with a soccer ball. These round balls from "association football" were made, at the time, with a set of laces to close off the hole needed for inserting the inflatable bladder after the other sewn-together segments of the ball's cover had been flipped outside-in; these laces could dribbling to be unpredictable. A lace-free ball construction method was invented, this change to the game was endorsed by Naismith; the first balls made for basketball were brown, it was only in the late 1950s that Tony Hinkle, searching for a ball that would be more visible to players and spectators alike, introduced the orange ball, now in common use. Dribbling was not part of the original game except for the "bounce pass" to teammates. Passing the ball was the primary means of ball movement. Dribbling was introduced but limited by the asymmetric shape of early balls. Dribbling was common by 1896, with a rule against the double dribble by 1898; the peach baskets were used until 1906 when they were replaced by metal hoops with backboards.
A further change was soon made, so the ball passed through. Whenever a person got the ball in the basket, his team would gain a point. Whichever team got; the baskets were nailed to the mezzanine balcony of the playing court, but this proved impractical when spectators in the balcony began to interfere with shots. The backboard was introduced to prevent this interference. Naismith's handwritten diaries, discovered by his granddaughter in early 2006, indicate that he was nervous about the new game he had invented, which incorporated rules from a children's game called duck on a rock, as many had failed before it.

Singapore the Republic of Singapore, is an island city-state in Southeast Asia. It lies one degree north of the equator, at the southern tip of the Malay Peninsula, with Indonesia's Riau Islands to the south and Peninsular Malaysia to the north. Singapore's territory consists of one main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23%; the country is known for its transition from a developing to a developed one in a single generation under the leadership of its founder Lee Kuan Yew. In 1819, Sir Stamford Raffles founded colonial Singapore as a trading post of the British East India Company. After the company's collapse in 1858, the islands were ceded to the British Raj as a crown colony. During the Second World War, Singapore was occupied by Japan, it gained independence from the British Empire in 1963 by joining Malaysia along with other former British territories, but separated two years over ideological differences, becoming a sovereign nation in 1965.
After early years of turbulence and despite lacking natural resources and a hinterland, the nation developed as an Asian Tiger economy, based on external trade and its workforce. Singapore is a global hub for education, finance, human capital, logistics, technology, tourism and transport; the city ranks in numerous international rankings, has been recognised as the most "technology-ready" nation, top International-meetings city, city with "best investment potential", world's smartest city, world's safest country, second-most competitive country, third least-corrupt country, third-largest foreign exchange market, third-largest financial centre, third-largest oil refining and trading centre, fifth-most innovative country, the second-busiest container port. The Economist has ranked Singapore as the most expensive city to live in, since 2013, it is identified as a tax haven. Singapore is the only country in Asia with an AAA sovereign rating from all major rating agencies, one of 11 worldwide. Globally, the Port of Singapore and Changi Airport have held the titles of leading "Maritime Capital" and "Best Airport" for consecutive years, while Singapore Airlines is the 2018 "World's Best Airline".
Singapore ranks 9th on the UN Human Development Index with the 3rd highest GDP per capita. It is placed in key social indicators: education, life expectancy, quality of life, personal safety and housing. Although income inequality is high, 90% of homes are owner-occupied. According to the Democracy Index, the country is described as a "flawed democracy"; the city-state is home to 5.6 million residents, 39% of whom are foreign nationals, including permanent residents. There are four official languages: English, Mandarin Chinese, Tamil, its cultural diversity is reflected in major festivals. Pew Research has found. Multiracialism has been enshrined in its constitution since independence, continues to shape national policies in education, politics, among others. Singapore is a unitary parliamentary republic with a Westminster system of unicameral parliamentary government; the People's Action Party has won every election since self-government began in 1959. As one of the five founding members of ASEAN, Singapore is the host of the Asia-Pacific Economic Cooperation Secretariat and Pacific Economic Cooperation Council Secretariat, as well as many international conferences and events.
It is a member of the East Asia Summit, Non-Aligned Movement and the Commonwealth of Nations. The English name of Singapore is an anglicisation of the native Malay name for the country, in turn derived from Sanskrit, hence the customary reference to the nation as the Lion City, its inclusion in many of the nation's symbols. However, it is unlikely that lions lived on the island. There are however other suggestions for the origin of the name and scholars do not believe that the origin of the name is established; the central island has been called Pulau Ujong as far back as the third century CE "island at the end" in Malay. Singapore is referred to as the Garden City for its tree-lined streets and greening efforts since independence, the Little Red Dot for how the island-nation is depicted on many maps of the world and Asia, as a red dot. Singapore is referred to as the "Switzerland of Asia" in 2017 due to its neutrality on international and regional issues; the Greco-Roman astronomer Ptolemy identified a place called Sabana in the general area in the second century, the earliest written record of Singapore occurs in a Chinese account from the third century, describing the island of Pu Luo Chung.
This was itself a transliteration from the Malay name "Pulau Ujong", or "island at the end". The Nagarakretagama, a Javanese epic poem written in 1365, referred to a settlement on the island called Tumasik. In 1299, according to the Malay Annals, the Kingdom of Singapura was founded on the island by Sang Nila Utama. Although the historicity
Cycling called biking or bicycling, is the use of bicycles for transport, exercise or sport. People engaged in cycling are referred to as "cyclists", "bikers", or less as "bicyclists". Apart from two-wheeled bicycles, "cycling" includes the riding of unicycles, quadracycles and similar human-powered vehicles. Bicycles were introduced in the 19th century and now number one billion worldwide, they are the principal means of transportation in many parts of the world. Cycling is regarded as a effective and efficient mode of transportation optimal for short to moderate distances. Bicycles provide numerous benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, access to roads, bike paths and rural trails. Cycling offers a reduced consumption of fossil fuels, less air or noise pollution, much reduced traffic congestion; these lead to less financial cost to the user as well as to society at large. By fitting bicycle racks on the front of buses, transit agencies can increase the areas they can serve.
Among the disadvantages of cycling are the requirement of bicycles to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles longer travel time, vulnerability to weather conditions, difficulty in transporting passengers, the fact that a basic level of fitness is required for cycling moderate to long distances. Cycling became an activity after bicycles were introduced in the 19th century. Today, over 50 percent of the human population knows. In many countries, the most used vehicle for road transport is a utility bicycle; these have frames with relaxed geometry, protecting the rider from shocks of the road and easing steering at low speeds. Utility bicycles tend to be equipped with accessories such as mudguards, pannier racks and lights, which extends their usefulness on a daily basis; as the bicycle is so effective as a means of transportation various companies have developed methods of carrying anything from the weekly shop to children on bicycles.
Certain countries rely on bicycles and their culture has developed around the bicycle as a primary form of transport. In Europe and the Netherlands have the most bicycles per capita and most use bicycles for everyday transport. Road bikes tend to have a more upright shape and a shorter wheelbase, which make the bike more mobile but harder to ride slowly; the design, coupled with low or dropped handlebars, requires the rider to bend forward more, making use of stronger muscles and reducing air resistance at high speed. The price of a new bicycle can range from US$50 to more than US$20,000, depending on quality and weight. However, UCI regulations stipulate. Being measured for a bike and taking it for a test ride are recommended before buying; the drivetrain components of the bike should be considered. A middle grade dérailleur is sufficient for a beginner, although many utility bikes are equipped with hub gears. If the rider plans a significant amount of hillclimbing, a triple-chainrings crankset gear system may be preferred.
Otherwise, the lighter and less expensive double chainring may be better. Much simpler fixed wheel bikes are available. Many road bikes, along with mountain bikes, include clipless pedals to which special shoes attach, via a cleat, enabling the rider to pull on the pedals as well as push. Other possible accessories for the bicycle include front and rear lights, bells or horns, child carrying seats, cycling computers with GPS, bar tape, baggage racks, baggage carriers and pannier bags, water bottles and bottle cages. For basic maintenance and repairs cyclists can carry a pump, a puncture repair kit, a spare inner tube, tire levers and a set of allen keys. Cycling can be more efficient and comfortable with special shoes and shorts. In wet weather, riding can be more tolerable with waterproof clothes, such as cape, jacket and overshoes and high-visibility clothing is advisable to reduce the risk from motor vehicle users. Items required in some jurisdictions, or voluntarily adopted for safety reasons, include bicycle helmets, generator or battery operated lights and audible signalling devices such as a bell or horn.
Extras include a bicycle computer. Bikes can be customized, with different seat designs and handle bars, for example. Many schools and police departments run educational programs to instruct children in bicycle handling skills and introduce them to the rules of the road as they apply to cyclists. In different countries these may be known as bicycle rodeos or operated as schemes such as Bikeability. Education for adult cyclists is available from organizations such as the League of American Bicyclists. Beyond riding, another skill is riding efficiently and safely in traffic. One popular approach to riding in motor vehicle traffic is vehicular cycling, occupying road space as car does. Alternately, in countries such as Denmark and the Netherlands, where cycling is popular, cyclists are segregated into bike lanes at the side of, or more separate from, main highways and roads. Many primary schools participate in the national road test in whi
National Stadium (Thailand)
The National Stadium of Thailand is a sports complex located in Pathum Wan District, Bangkok. Founded in 1937 with the construction of Supachalasai Stadium, its main venue, the complex has since expanded and now consists of multiple stadia and sporting facilities, it is used for football matches. It served as the main stadium for the 1966, 1970, 1978 Asian Games, it was used for the 2007 AFC Asian Cup, but only for one game. The stadium is easy for spectators to get to as it is served by the BTS Skytrain which stops at the'National Stadium BTS station' right next to the stadium; the stadium is a single tier construction, uncovered on three sides. A plain but effective roof covers the main-stand side. Although there is a running track, the tribunes are adjacent to it so spectators are not as far from the action as they are at the newer Rajamangala Stadium. Spectator comfort was increased in 2007 with the addition of red bench seats to the bare concrete steps on the three open sides. Thai league clubs play at the Suphachalasai in Asian competitions as their own stadiums do not meet Asian Football Confederation criteria.
However, it is now used by the national team who play at the Rajamangala National Stadium. Other stadiums in Bangkok include the Thai Army Sports Stadium, the Thai-Japanese Stadium and Chulalongkorn University Stadium. Entertainer Michael Jackson performed 2 concerts there during his Dangerous World Tour on 24 and 27 August 1993 in front of 140,000 in attendance. Suphachalasai Stadium is the majority part of the National Stadium, it is the multi-purpose stadium with track and field for athletic purposes, as well as a partial roof on one of its side. With its capacity of 19,793, the stadium is being used to hold important matches such as the Thai FA Cup and Thai League Cup. Thephasadin Stadium was constructed in 1965 for the use in 1966 Asian Games as the Hockey venue, hence its original name, Hockey Field, it was renamed in 1983 in memorial of Sanan Thephasadin na Ayutthaya, considered the Father of Thai Football. With its capacity of 6,378 seats, it was retired from being the hockey stadium. Jindarat Stadium, constructed after the Pacific War, was used as the outdoor stadium for medium-level sporting events and practicing purposes.
It was named Ton Pho Stadium, but was renamed in 1983 in memorial of Jindarat, former director of the Office of Sports and Recreation Development. Wisutamol Pool was constructed in 1961 under the term of director Kong Wisutamol, it was the Olympic-size swimming pool with two sides of stands, used for the competition and general practices. Named the Olympic Pool, it was renamed in memorial of the director Wisutamol who organized the construction. Nimibutr Stadium, opened in 1963 is an indoor stadium used for sports including boxing, gymnastics, futsal and handball. Jhanthana-Yingyong Gymnasium was built in 1965.

Sport of athletics
Athletics is a collection of sporting events that involve competitive running, jumping and walking. The most common types of athletics competitions are track and field, road running, cross country running, walking race; the results of racing events are decided by finishing position, while the jumps and throws are won by the athlete that achieves the highest or furthest measurement from a series of attempts. The simplicity of the competitions, the lack of a need for expensive equipment, makes athletics one of the most competed sports in the world. Athletics is an individual sport, with the exception of relay races and competitions which combine athletes' performances for a team score, such as cross country. Organized athletics are traced back to the Ancient Olympic Games from 776 BC; the rules and format of the modern events in athletics were defined in Western Europe and North America in the 19th and early 20th century, were spread to other parts of the world. Most modern top level meetings are conducted by the International Association of Athletics Federations and its member federations.
The athletics meeting forms the backbone of the Summer Olympics. The foremost international athletics meeting is the IAAF World Championships in Athletics, which incorporates track and field, marathon running and race walking. Other top level competitions in athletics include the IAAF World Cross Country Championships and the IAAF World Half Marathon Championships. Athletes with a physical disability compete at the Summer Paralympics and the World Para Athletics Championships; the word athletics is derived from the Ancient Greek ἀθλητής from ἆθλον or ἆθλος. The term was used to describe athletic contests in general – i.e. sporting competition based on human physical feats. In the 19th century, the term athletics acquired a more narrow definition in Europe and came to describe sports involving competitive running, walking and throwing; this definition continues to be the most prominent one in the United Kingdom and most of the areas of the former British Empire. Furthermore, foreign words in many Germanic and Romance languages which are related to the term athletics have a similar meaning.
In much of North America, athletics is synonymous with sports in general, maintaining a more historical usage of the term. The word "athletics" is used to refer to the sport of athletics in this region. Track and field is preferred, is used in the United States and Canada to refer to most athletics events, including racewalking and marathon running. Athletic contests in running, walking 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 and high jumping appearing in tombs from as early as of 2250 BC; the Tailteann Games were an ancient Celtic festival in Ireland, founded circa 1800 BC, the thirty-day meeting included running and stone-throwing among its sporting events. The original and only event at the first Olympics in 776 BC was a stadium-length running event known as the stadion; this expanded to include throwing and jumping events within the ancient pentathlon.
Athletics competitions took place at other Panhellenic Games, which were founded around 500 BC. The Cotswold Olimpick Games, a sports festival which emerged in 17th century England, featured athletics in the form of sledgehammer throwing contests. Annually, from 1796 to 1798, L'Olympiade de la République was held in revolutionary France, is an early forerunner to the Modern Summer Olympic Games; the premier event of this competition was a running event, but various ancient Greek disciplines were on display. The 1796 Olympiade marked the introduction of the metric system into the sport. Athletics competitions were held about 1812 at the Royal Military College, in 1840 in Shrewsbury, Shropshire at the Royal Shrewsbury School Hunt; the Royal Military Academy at Woolwich held an organised competition in 1849, a regular series of closed meetings open only to undergraduates, was held by Exeter College, Oxford from 1850. The annual Wenlock Olympian Games, first held in 1850 in Wenlock, incorporated athletics events into its sports programme.
The first modern-style indoor athletics meetings were recorded shortly after in the 1860s, including a meet at Ashburnham Hall in London which featured four running events and a triple jump competition. The Amateur Athletic Association was established in England on 1880 as the first national body for the sport of athletics and began holding its own annual athletics competition – the AAA Championships; the United States began holding an annual national competition – the USA Outdoor Track and Field Championships – first held in 1876 by the New York Athletic Club. Athletics became codified and standardized via the English AAA and other general sports organisations in the late 19th century, such as the Amateur Athletic Union and the Union des sociétés françaises de sports athlétiques. An athletics competition was included in the first modern Olympic Games in 1896 and it has been as one of the foremost competitions at the quadrennial multi-sport event since. For men only, the 1928 Olympics saw the introduction of women's events in the athletics programme.
Athletics is part of the Paralympic Games since the inaugural Games in 1960. Athletics has a high-profile during major championships the Olympics, but otherwise is less popular. An internation
