Squash, a game of strategy and endurance, is played with a racket and
a round ball in a four-walled rectangular court. Players attempt
to hit a small synthetic rubber ball in such a manner that their opponent
cannot return it. Invented in England early in the 19th century,
squash came to North America in 1885. English-speaking countries
have tended to dominate championship play.
Historically, from the 1930s through the 1980s, squash racket frames were
made from glued wood, and had a fairly small round head, but modern
racket frames are made from graphite composites, and they have larger
heads with synthetic strings. These rackets offer greater hitting
power and a larger "sweet spot" than the older style rackets.
Hollow, rubber squash balls weigh 24 grams and measure between 40 to 45
millimeters in diameter. Blue dots designate "high-bounce" training
balls; yellow dots designate "low-bounce" competition balls. Squash
shoes have a light-colored sole to avoid scuffing the floor of the court;
some players wear protective goggles.
