If someone serves, and then goes through every spot and is going back to serve, then they can be subbed. If someone is serving and served once and made it over got a point, and gets to serve again without changing positions then no you can't sub in.
yes, they are one of the six players at a time
Yes, as someone on the bench could be a better server than the person about to serve. with what ever you are doing
As soon as the ball is out of possesion of a server.
The server serves the volleyball, behind the last line (at least 30 feet).
The number for the server's position is 1.
Anywhere behind the back line of the court.
In volleyball when does the team rotate
at the back of the court
a volleyball server is the player who will be serving the ball...A server in vollyball is someone who over hands serve or underhand they get to serve as many times as they want as long as the team they are on is winning. - hoped it helped :)
