Blocking is often done to protect a teammate who’s in the lead (cycling) block in volleyball a defensive formation of the net players for defending spikes hit by the opponent. The block is usually played by two players (double block), sometimes also with three players (triple block) or one player (single block). The timing of the initiation of the block is crucial. The players performing the block must jump up shortly after the attacker. The block is set-up within reach of the net with a strong push-off, straight arms and fingers spread out either as an active block with the aim of scoring a point or gaining the right to serve or as a passive block which reduces the effect of the attack and makes a controlled attack formation of the own team possible. An additional field player is positioned for block safety, i.E. He defends the zone that has become free due to the block player moving up and attempting to reach balls lobbed over the top of the block or deflected off the block. (H.Haag &g.
