EXAMINATION OF ACUTE WHOLE-BODY VIBRATION ON MAXIMAL VERTICAL JUMP HEIGHT IN COLLEGIATE VOLLEYBALL ATHLETES

Abstract

The purpose of this study was to compare the acute effects on maximal countermovement vertical jump after completing three sets of 30 second body weight squats with and without whole body vibration among Division I volleyball players. Participants (n=7) underwent three days of testing: one baseline, one with WBV at 45 Hertz and one without WBV. The latter two testing days involved a warm-up with three sets of 30-second body weight squats on a vibration platform. Each participant then completed a countermovement vertical jump, measured by a Vertec, after passively resting for one minute and five minutes, respectively. Results indicated a significant difference between baseline and vibration vertical jump means (p=.039). No other significant differences were detected.
