saudi turf team Squash (sport)



Squash is a racket sport played by two (singles) or four players (doubles) in a four-walled court with a small, hollow rubber ball. The players must alternate in striking the ball with their racket and hit the ball onto the playable surfaces of the four walls of the court.
The game was formerly called squash rackets, a reference to the "squash able" soft ball used in the game (compared with the harder ball used in its sister game rackets).
Squash is recognized by the IOC and supporters are lobbying for its incorporation in a future Olympic program.
The use of stringed rackets is shared with tennis, which dates from the late sixteenth century, though is more directly descended from the game of rackets from England. In "rackets", instead of hitting over a net as in sports such as tennis, players hit a squeezable ball against walls.
Old and new style squash rackets
Squash was invented in Harrow School out of the older game rackets around 1830 before the game spread to other schools, eventually becoming an international sport. The first courts built at this school were rather dangerous because they were near water pipes, buttresses, chimneys, and ledges. The school soon built four outside courts. Natural rubber was the material of choice for the ball. Students modified their rackets to have a smaller reach to play in these cramped conditions.
The rackets have changed in a similar way to those used in tennis. Squash rackets used to be made out of laminated timber In the 1980s, construction shifted to lighter materials (such as aluminium and graphite) with small additions of components like Kevlar, boron and titanium. Natural "gut" strings were also replaced with synthetic strings.
In the 19th century the game increased in popularity with various schools, clubs and even private citizens building squash courts, but with no set dimensions. The first squash court in North America appeared at St. Paul's School in Concord, New Hampshire in 1884. In 1904 in Philadelphia, Pennsylvania, the earliest national association of squash in the world was formed as the United States Squash rackets Association, (USSRA), now known as U.S. Squash. In April 1907 the Tennis, rackets & Fives Association set up a sub committee to set standards for squash. Then the sport soon formed, combining the three sports together called “Squash”. In 1912, the RMS Titanic had a squash court in first class. The 1st-Class Squash Court was situated on G-Deck and the Spectators Viewing Gallery was on the deck above on F-Deck. To use the Court cost 50 cents in 1912. Passengers could use the court for 1 hour unless others were waiting. It was not until 1923 that the Royal Automobile Club hosted a meeting to further discuss the rules and regulations and another five years elapsed before the Squash rackets Association was formed to set standards for squash in Great Britain.
Standard rackets are governed by the rules of the game. Traditionally they were made of laminated wood (typically ash), with a small strung area using natural gut strings. After a rule change in the mid-1980s, they are now almost always made of composite materials or metals (graphite, Kevlar, titanium, boron) with synthetic strings. Modern rackets have maximum dimensions of 686 mm (27.0 in) long and 215 mm (8.5 in) wide, with a maximum strung area of 500 square centimetres (90 sq in). The permitted maximum weight is 255 grams (9.0 oz), but most have a weight between 90 and 150 grams (3–5.3 oz.).
Squash balls are between 39.5 and 40.5 mm in diameter, and have a weight of 23 to 25 grams.They are made with two pieces of rubber compound, glued together to form a hollow sphere and buffed to a matte finish. Different balls are provided for varying temperature and atmospheric conditions and standards of play: more experienced players use slow balls that have less bounce than those used by less experienced players (slower balls tend to "die" in court corners, rather than "standing up" to allow easier shots). Depending on its specific rubber composition, a squash ball has the property that it bounces more at higher temperatures. Squash balls must be hit dozens of times to warm them up at the beginning of a session; cold squash balls have very little bounce. Small colored dots on the ball indicate its dynamic level (bounciness), and thus the standard of play for which it is suited. The recognized speed colors indicating the degree of dynamism are:
Some ball manufacturers such as Dunlop use a different method of grading balls based on experience. They still have the equivalent dot rating, but are named to help choose a ball that is appropriate for one's skill level. The four different ball types are Intro (Blue dot), Progress (Red dot), Competition (single yellow dot) and Pro (double yellow dot).
The "double-yellow dot" ball, introduced in 2000, is the competition standard, replacing the earlier "yellow-dot" ball. There is also an "orange dot" ball.
Players wear comfortable sports clothing. In competition, men usually wear shorts and a T-shirt, tank top or a polo shirt. Women normally wear a skirt or skort and a T-shirt or a tank top, or a sports dress. The National Institutes of Health recommends wearing goggles with polycar bonate lenses.
Many squash venues mandate the use of eye protection and some association rules require that all juniors and doubles players must wear eye protection.
The squash court is a playing surface surrounded by four walls. The court surface contains a front line separating the front and back of the court and a half court line, separating the left and right hand sides of the back portion of the court, creating three 'boxes': the front half, the back left quarter and the back right quarter. Both the back two boxes contain smaller service boxes. The floor-markings on a squash court are only relevant during serves.
There are four walls to a squash court. The front wall, on which three parallel lines are marked, has the largest playing surface, whilst the back wall, which typically contains the entrance to the court, has the smallest. The out line runs along the top of the front wall, descending along the side walls to the back wall. There are no other markings on the side or back walls. Shots struck above or touching the out line, on any wall, are out. The bottom line of the front wall marks the top of the 'tin', a half metre-high metal area which if struck means that the ball is out. In this way the tin can be seen as analogous to the net in other racket sports such as tennis. The middle line of the front wall is the service line and is only relevant during serves.
The players spin a racket to decide who serves first. This player starts the first rally by electing to serve from either the left or right service box. For a legal serve, one of the server's feet must be touching the service box, not touching any part of the service box lines, as the player strikes the ball. After being struck by the racket, the ball must strike the front wall above the service line and below the out line and land in the opposite back quarter court. The receiving player can choose to volley a serve after it has hit the front wall. If the server wins the point, the two players switch sides for the following point.
