What is the main responsibility of the Libero during the match?

The main responsibility of the Libero during a volleyball match is to specialize in defensive plays and receiving serves. The Libero is a back-row player who is allowed to replace any back-row player without prior notice to the officials. This specialized role is critical because the Libero is typically one of the best defenders on the team, focusing on digging and passing during rallies. They wear a different color jersey to distinguish themselves from other players, highlighting their unique position within the team.

By focusing on defense, the Libero contributes to maintaining a strong reception against serves and attacks from the opposing team, which are vital for creating successful offensive plays. Additionally, this player's involvement enhances the team's overall defensive strategy, allowing other players to concentrate on offensive roles without the same emphasis on receiving and digging.
