Football 5-a-side, also known as blind football, is an adaptation of football for athletes with a vision impairment. It was included at the Paralympic Games at Athens 2004, and has been contested at every Games since. World Championships take place every four years in between the Paralympics.
Football 5-a-side teams are made up of four outfield players and one goalkeeper.
The duration of the match is 50 minutes, divided into two 25-minute halves. Each team can request a one-minute time-out in each half. During the last two minutes of both halves, and in case of an extra time, the timekeeper must stop the clock for a free kick, kick-in, goal kick and corner kick.
