Squash is a ball sport played by two (singles) or four players (doubles squash) in a four-walled court with a small, hollow rubber ball. The players must alternate in striking the ball with their racquet 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 “squashable” soft ball used in the game (compared with the harder ball used in its sister game rackets).
The governing body of Squash, the World Squash Federation (WSF) is recognised by the International Olympic Committee (IOC), but the sport is not part of the Olympic Games, despite a number of applications. Supporters continue to lobby for its incorporation in a future Olympic program.
