Special Olympics feature:

We have volleyball in three forms/types.

• In modified volleyball, volleyball players play slower than usual and use a larger, lighter ball.
• Traditional volleyball involves athletes who play with a standard volleyball.
• In unified volleyball, a person with an intellectual disability and a person without an intellectual disability play in tandem.

The peculiarity of Special Olympics Volleyball is the rule that a person may make a maximum of three serves in a row. Basically, the rules of the game correspond to those of the Fédération Internationale de Volleyball (FIVB). There are slight adaptations in terms of court size, net height and weight, and size of the ball.
 

We have two competitions:

1. Unified Sports Team Competition - Men/Mixed
2. Unified Sports Team Competition - Women
