THE JUMP TOPSPIN Learn from Dr. Gylton Da Matta, a member of the International Volleyball Federation technical development committee. The jump Top Spin is a type of serve in which the player tosses the ball high, with one or two hands, jumps, and executes a spike action to put the ball in play at the opposing court. Also called Spike serve, the jump serve increases the speed and power of the serve creating major difficulties for serve-receivers to pass the ball properly.
