What do you call the player who has specialized training to play only in the back row?

The player who has specialized training to play only in the back row is known as the libero. The libero has a distinct role on the volleyball team, primarily focusing on defensive skills and serve-receive situations. This position is characterized by the utilization of a different uniform, which is typically a contrasting color to distinguish them from the other players on the court. The libero cannot attack the ball above the net's height and is not allowed to serve, block, or attempt to block, enhancing their defensive specialization. Their training equips them with skills such as digging, passing, and overall court awareness, making them invaluable to the team’s defensive strategy. This role is essential in maximizing team performance, particularly in coverage against opposing serves and attacks.
