What is meant by a "double hit" in volleyball?

A "double hit" in volleyball specifically refers to a situation where a single player hits the ball twice in succession. This often happens when the ball contacts a player's body on two separate occasions during a single attempt to play the ball, such as when it comes to rest briefly on their hands or arms before being struck again. According to the rules of volleyball, this is typically considered a fault, as players are only allowed to make one contact with the ball unless it is during a block or the first touch of a rally, where more leeway is often given.

Other choices involve scenarios that do not align with the technical definition of a "double hit." For instance, simultaneous contact by two players is a different situation and is not categorized as a double hit. Likewise, hitting the ball twice in one motion might refer to a controlled action that could be permissible in some contexts under specific rules but it does not define a double hit itself. Lastly, hitting the ball more than three times falls under the concept of how many total hits a team can have before the ball must go over the net, which again is separate from what constitutes a double hit.
