A player who blocks the ball may be the first to contact the ball after the block. A player may place her hands and arms beyond the net in an attempt to block if she does not interfere with her opponents' play. An example of interference is when an offensive player is setting a pass and a defensive player touches the ball with her hands or arms over the net. It is not interference if the defensive player touches the ball beyond the net when the offensive team is attaching.
Consecutive contacts with the ball are permitted in blocking if the contacts are quick and continuous and made during one action. A serve cannot be blocked.
How does one block? Stand next to the net about one foot away, your arms should be near your head with your hands in read position, jump up penetrate your hands and arms over the net bending your body in a crescent shape to stay out of the net. Your body must be firm when blocking a ball. If your arms are not firm and the ball hits them then the ball will come straight down the net in front of you. Cues for blocking: (1) Vision sequence (passer, setter, hitter)- when the hitter is contacting the ball you better be up and ready. (2) One move (seal the net, slide over)- cover your portion of the net move with your hitter be ready. (3) Head down, eyes up- when blocking keep your eyes on the ball at all times. (4) Surround the ball- if you are keeping your eyes on the ball then you will be able to surround the ball with your hands when it comes to you. (5) Recover (expect deflections and digs in your blocking area)- if you don't block the ball onto your opponents side you need to be ready pick up a ball you deflected or be ready to get out of someone’s way who is going to dig the ball.
Now look at the pictures below. Try to point out what the blockers are doing right and wrong. What do you think a blocker could do to better there blocking form? Please be specific.
