Tennis Players At The 2020 Summer Olympics
Tennis is a racket sport that is played either individually against a single opponent ( singles) or between two teams of two players each ( doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to manoeuvre the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball validly will not gain a point, while the opposite player will. Tennis is an Olympic sport and is played at all levels of society and at all ages. The sport can be played by anyone who can hold a racket, including wheelchair users. The modern game of tennis originated in Birmingham, England, in the late 19th century as lawn tennis. It had close connections both to various field (lawn) games such as croquet and bowls as well as to the older racket sport today called real tennis. The rules of modern tennis have cha ...

Tennis Court
A tennis court is the venue where the sport of tennis is played. It is a firm rectangular surface with a low net stretched across the centre. The same surface can be used to play both doubles and singles matches. A variety of surfaces can be used to create a tennis court, each with its own characteristics which affect the playing style of the game. Dimensions The dimensions of a tennis court are defined and regulated by the International Tennis Federation (ITF) governing body and are written down in the annual 'Rules of Tennis' document. The court is long. Its width is for singles matches and for doubles matches. The service line is from the net. Additional clear space around the court is needed in order for players to reach overrun balls for a total of wide and long. A net is stretched across the full width of the court, parallel with the baselines, dividing it into two equal ends. The net is high at the posts, and high in the center. The net posts are outside the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Championships, Wimbledon
The Wimbledon Championships, commonly known simply as Wimbledon, is the oldest tennis tournament in the world and is widely regarded as the most prestigious. It has been held at the All England Lawn Tennis and Croquet Club, All England Club in Wimbledon, London, since 1877 and is played on outdoor grass courts, with retractable roofs over the two main courts since 2019. Wimbledon is one of the four Grand Slam (tennis), Grand Slam tennis tournaments, the others being the Australian Open, the French Open, and the US Open (tennis), US Open. Wimbledon is the only major still played on grass, the traditional tennis playing surface. Also, it is the only Grand Slam that retains a night-time curfew, though matches can now continue until 11.00 pm under the lights. The tournament traditionally takes place over two weeks in late June and early July, starting on the last Monday in June and culminating with the Ladies' and Gentlemen's Singles Finals, scheduled for the Saturday and Sunday ...

Clay Court
A clay court is one of the types of tennis court on which the sport of tennis, originally known as "lawn tennis", is played. Clay courts are made of crushed stone, brick, shale, or other unbound mineral aggregate depending on the tournament. The French Open uses clay courts, the only Grand Slam tournament to do so. Clay courts are more common in Continental Europe and Latin America than in North America, Asia-Pacific or Britain. Two main types exist: red clay, the more common variety, and green clay, also known as "rubico", which is a harder surface. Although less expensive to construct than other types of tennis courts, the maintenance costs of clay are high as the surface must be rolled to preserve flatness. Play Clay courts are considered "slow" because the balls bounce relatively high and lose much of their initial speed when contacting the surface, making it more difficult for a player to deliver an unreturnable shot. Points are usually longer as there are fewer winn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Open
The French Open (french: Internationaux de France de tennis), also known as Roland-Garros (), is a major tennis tournament held over two weeks at the Stade Roland Garros in Paris, France, beginning in late May each year. The tournament and venue are named after the French aviator Roland Garros. The French Open is the premier clay court championship in the world and the only Grand Slam tournament currently held on this surface. It is chronologically the second of the four annual Grand Slam tournaments, occurring after the Australian Open and before Wimbledon and the US Open. Until 1975, the French Open was the only major tournament not played on grass. Between the seven rounds needed for a championship, the clay surface characteristics (slower pace, higher bounce), and the best-of-five-set men's singles matches, the French Open is widely regarded as the most physically demanding tennis tournament in the world.

Hardcourt
A hardcourt (or hard court) is a surface or floor on which a sport is played, most usually in reference to tennis courts. It is typically made of rigid materials such as asphalt or concrete, and covered with acrylic resins to seal the surface and mark the playing lines, while providing some cushioning. Historically, hardwood surfaces were also in use in indoor settings, similar to an indoor basketball court, but these surfaces are rare now. Tennis Tennis hard courts are made of synthetic/acrylic layers on top of a concrete or asphalt foundation and can vary in color. These courts tend to play medium-fast to fast because there is little energy absorption by the court, as with grass courts but unlike clay courts. The ball tends to bounce high and players are able to apply many types of spin during play. Flat balls are favored on hard courts because of the extremely quick play style. Speed of rebound after tennis balls bounce on hard courts is determined by how much sand is in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grand Slam (tennis)
The Grand Slam in tennis is the achievement of winning all four major championships in one discipline in a calendar year, also referred to as the "Calendar-year Grand Slam" or "Calendar Slam". In doubles, a team may accomplish the Grand Slam playing together or a player may achieve it with different partners. Winning all four major championships consecutively but not within the same calendar year is referred to as a "non-calendar-year Grand Slam", while winning the four majors at any point during the course of a career is known as a "Career Grand Slam". The Grand Slam tournaments, also referred to as majors, are the world's four most important annual professional tennis tournaments. They offer the most ranking points, prize money, public and media attention, the greatest strength and size of field, and the longest matches for men (best of five sets, best of three for the women). The tournaments are overseen by the International Tennis Federation (ITF), rather than the separate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawk-Eye
Hawk-Eye is a computer vision system used in numerous sports such as cricket, tennis, Gaelic football, badminton, hurling, rugby union, association football and volleyball, to visually track the trajectory of the ball and display a profile of its statistically most likely path as a moving image. The onscreen representation of the trajectory results is called Shot Spot. The Sony-owned Hawk-Eye system was developed in the United Kingdom by Paul Hawkins. The system was originally implemented in 2000 for television purposes in cricket. The system works via six (sometimes seven) high-performance cameras, normally positioned on the underside of the stadium roof, which track the ball from different angles. The video from the six cameras is then triangulated and combined to create a three-dimensional representation of the ball's trajectory. Hawk-Eye is not infallible, but is advertised to be accurate to within 3.6 millimetres and generally trusted as an impartial second opinion in sp ...

Line Call
In sports, a line call occurs when there is doubt as to whether a specific and significant event took place, for example, whether the ball in tennis touched the line rather than landing outside the court. The phrase ''line call'' is more generally used to indicate any decision in which the correct course is uncertain. The official rules of most sports indicate how line calls are to be resolved. The actual phrase ''line call'' may or may not appear in the official rules. Cricket In cricket Cricket is a bat-and-ball game played between two teams of eleven players on a field at the centre of which is a pitch with a wicket at each end, each comprising two bails balanced on three stumps. The batting side scores runs by st ..., uncertainty is generally resolved in the manner most favourable to the batsman.

Tiebreak (tennis)
The tennis scoring system is a standard widespread method for scoring tennis matches, including pick-up games. Some tennis matches are played as part of a tournament, which may have various categories, such as singles and doubles. The great majority are organised as a single-elimination tournament, with competitors being eliminated after a single loss, and the overall winner being the last competitor without a loss. Optimally, such tournaments have a number of competitors equal to a power of two in order to fully fill out a single elimination bracket. In many professional and top-level amateur events, the brackets are seeded according to a recognised ranking system, in order to keep the best players in the field from facing each other until as late in the tournament as possible; additionally, if byes are necessary because of a less-than-full bracket, those byes in the first round are usually given to the highest-seeded competitors. A tennis match is composed of points, games, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Real Tennis
Real tennis – one of several games sometimes called "the sport of kings" – is the original racquet sport from which the modern game of tennis (also called "lawn tennis") is derived. It is also known as court tennis in the United States, formerly royal tennis in England and Australia, and ''courte-paume'' in France (to distinguish it from longue-paume, and in reference to the older, racquetless game of '' jeu de paume'', the ancestor of modern handball and racquet games). Many French real tennis courts are at ''jeu de paume'' clubs. The term ''real'' was first used by journalists in the early 20th century as a retronym to distinguish the ancient game from modern ''lawn'' tennis (even though, at present, the latter sport is seldom contested on lawns outside the few social-club-managed estates such as Wimbledon). There are more than 50 active real tennis courts in the world, located in the United Kingdom, Australia, the United States and France. Other countries ha ...

Bowls
Bowls, also known as lawn bowls or lawn bowling, 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 bowling green, which may be flat (for "flat-green bowls") or convex or uneven (for " crown green bowls"). It is normally played outdoors (although there are many indoor venues) and the outdoor surface is either natural grass, artificial turf or cotula (in New Zealand). History Bowls is a variant of the '' boules'' games (Italian '' Bocce''), which, in their general form, are of ancient or prehistoric origin. Ancient Greek variants are recorded that involved throwing light objects (such as flat stones, coins, or later also stone balls) as far as possible. The aspect of tossing the balls to approach a target as closely as possible is recorded in ancient Rome. This game was spread to Roman Gaul by soldiers or sailors. A Roman sepulchre in Florence shows people playing this game, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
