Goalball was officially included in the Paralympic Programme in the 1976 Toronto Games and is a sport exclusively for people with visual impairment.
The game consists of using the hands to roll a ball on the floor, in the direction of the adversary’s goal, while the opponent tries to block it with their body. The court has the same dimensions as a Volleyball court and the goal spans the entire width of the goal line.
Each team remains on their side of the field, with three players each and, at most, three substitutes on the bench. The players are oriented by a bell inside the ball, and therefore, complete silence of the spectators is necessary.
