The maximum number of players permitted on a volleyball team during official matches is 12. However, only 6 players can be on the court at any given time during a match. Substitutions are allowed, enabling strategic changes and player rotations to occur throughout the game, typically allowing for a maximum of 6 substitutions per set. This structure helps teams manage player stamina and tactical adjustments, particularly in high-intensity situations. Each player's role varies, and the team's success relies on effective collaboration among all members, reinforcing the importance of teamwork in volleyball.
