Teams aim to hit a ball over a net and land it within the opposition's court.
Teams have three passes, to form an attacking play, before the ball has to go over the net. Sitting Volleyball requires players to maintain contact between their pelvis and the floor at all times.
The sport features a smaller court (10 metres by six metres) and a lower net compared to its Olympic counterpart. The net height internationally is 1.15m (men) and 1.05m (women). As a result, Sitting Volleyball is faster than the Olympic indoor game. Another change from Olympic rules is that blocking of the serve is allowed.
Each team is allowed to feature six players on court, including a libero (defensive specialist), who will wear a different coloured shirt to the rest of the team, although five reserves are allowed. There are competitions for both men’s and women’s teams.
The first team to 25 points wins a set, but they must win by two clear points. The first team to win three sets is the winner. A maximum of five sets are played. If a match goes to a deciding fifth set, the first team to 15 points and with a two-point advantage wins.
All athletes with physical impairments are eligible. Most players are athletes who are amputees. In addition, two players on each team may have ‘minimal impairment’, which means their impairment may appear minimal but it prevents them from competing in the non-disabled version of the sport. These injuries include anterior cruciate ligament damage and missing fingers.
