Men and women compete separately in sitting volleyball at major Games. The teams are composed mainly of leg amputees while two players on each team may have and impairment that appears minimal but prevents them from competing in the non-disabled version of the sport. Apart from the players being seated, the other major differences are a smaller court, lower net and players must always keep contact with floor at all times except when making a defensive play in the back or front zones.
Each match is a best-of-five sets. The first four sets go to 25 points while a fifth and deciding set goes to 15. In all sets, the margin of victory must be at least two points. There are 12 players to a team max.
The court is divided into two sides of five metres deep by six metres wide. The net height, lower than that of able-bodied or standing volleyball, is set at a height of 1.15 metres for men, and 1.05 metres for women.
The World Organization Volleyball for Disabled is the International Sport Federation, with Volleyball Canada governing at the national level.
