An analysis of the biomechanics of the specific skills that are performed by volleyball athletes permits optimal sport performance while minimizing the risk of injury. Jumping ability is a key component of competitive success in indoor and beach volleyball. There is a deterministic relationship between the velocity of the center of mass (CoM) at take-off (vTO) and the height attained during a jump. The peak forces and loading rate during landing generally exceed those generated during take-off. During the overhead spike technique, the momentum (mass-velocity) of the hand is transferred to the ball. Coordinated muscle activity increases the momentum and the elastic properties of the hand. The volleyball trajectory is greatly affected by velocity and rotation. Depending on technique, ball trajectories are slightly different. During a set, the trajectory will be approximately parabolic because the ball has low velocity and no rotation.
