What is the purpose of a libero in volleyball?

The role of a libero in volleyball is specifically designed to enhance the defensive capabilities of the team. A libero is a specialized player who is typically shorter and more agile, focused primarily on receiving serves, digging attacks, and playing defense in the back row. The libero wears a different color jersey to distinguish them from the other players and cannot serve, attack the ball above the net, or block.

The primary purpose is to increase the team's overall defensive performance by ensuring strong passing and ball control, allowing skilled defenders to be on the court for longer durations without the challenges of rotation and substitution rules that apply to other players. This player's unique skills contribute significantly to maintaining the team's rhythm and stability during play.
