The Effect of Approach on Spike Jump Height for Female Volleyball Players

Abstract

The purpose of the study was to compare vertical jump height using a four-step approach volleyball spike jump (VBSJ) and a standing counter-movement jump (CMJ) for competitive female volleyball players. Ten NCAA Division I female volleyball players were recruited. Each participant performed jumps using two techniques: a four-step approach VBSJ and a standing CMJ. Mean jump height for the VBSJ (0.38 ± 0.06 m) was significantly greater than the CMJ (0.33 ± 0.05 m). No correlation between jump height and horizontal center of mass (CoM) velocity during the VBSJ approach was found. The results indicate that a four-step approach benefits jump height for elite female volleyball players. However, approach velocity is not a determining factor that makes a four-step approach more beneficial. Other characteristics, such as improved force development and power production may better explain the benefit of the VBSJ approach for female volleyball players.
