How many skaters are on the track during a roller derby bout?

In a standard roller derby bout, there are 10 skaters on the track at any given time. This number consists of two teams with five skaters each. Each team typically has four blockers and one jammer on the track. The blockers work together to impede the opposing team's jammer, while the jammer is focused on scoring points by lapping the opponents. This configuration of 10 skaters allows for a balance of offensive and defensive strategies, making the game dynamic and competitive. Understanding this structure is essential for appreciating the game's flow and the roles of each position within the teams.
