Events such as jumping, marathon, pentathlon, throwing, and track are continually being modified to include as many athletes as possible. Goalball is a sport played by visually impaired athletes. The team consists of three players who are on the court at one time. The object of this game is to throw the ball into the opponent's goal. Inside the ball is a bell whose purpose is to indicate from what direction the ball is coming.
Matches last a total of fourteen minutes and are divided into two seven minute halves.
To avoid advantages granted to the competitors with better eyesight, masks are worn over the eyes of all athletes. Boccia, a sport that tests the athletes' accuracy and muscle control, made its premiere during the 1992 Barcelona Games. Athletes who have cerebral palsy play boccia. In the 1996 Paralympic Games in Atlanta, Georgia, it became possible for athletes to use assistance from devices to shoot the leather balls for them. The game of boccia is played indoors on an even surface.
