DEPTH JUMP TRAINING AND THE VOLLEYBALL SPIKE

Abstract

The dynamics of movement often combine high strength demands with speed requirements. We speak of the rise time of a force. or the power (work done per unit of time) exhibited in the perfo-rmance of a task. Success in numerous sports is dependent upon the ahility to meet the strength-speed demands; and this practical need leads us to questions about how one improves dynamic capahilities. It has been suggested that plyometric training is a means to this end (Verhoshanski, 1968).
