Abstract

The purpose of this study was to evaluate the effect of different rest intervals following whole-body vibration on counter-movement vertical jump performance. Sixteen females, eight recreationally trained and eight varsity athletes volunteered to participate in four testing visits separated by 24 h. Visit one acted as a familiarization visit where subjects were introduced to the counter-movement vertical jump and whole-body vibration protocols. Visits 2–4 contained 2 randomized conditions. Whole-body vibration was administered in four bouts of 30 s with 30 s rest between bouts. During whole-body vibration subjects performed a quarter squat every 5 s, simulating a counter-movement vertical jump. Whole-body vibration was followed by three counter-movement vertical jumps with five different rest intervals between the vibration exposure and jumping. For a control condition, subjects performed squats with no whole-body vibration. There was a significant (p < 0.05) main effect for time for vertical jump height, peak power output, and relative ground reaction forces, where a majority of individuals max jump from all whole-body vibration conditions was greater than the control condition. There were significant (p < 0.05) group differences, showing that varsity athletes had a greater vertical jump height and peak power output compared to recreationally trained females. There were no significant (p > 0.05) group differences for relative ground reaction forces. Practitioners and/or strength and conditioning coaches may utilize whole-body vibration to enhance acute counter-movement vertical jump performance after identifying individuals optimal rest time in order to maximize the potentiating effects.

Highlights

Identifying key variables in an athlete’s performance is essential to improving athletic performance.It is common to use traditional training techniques, such as strength training, plyometrics, and weightlifting and it may be beneficial to incorporate non-traditional techniques to further enhance performance [1,2,3]
There was no significant interaction for training status and time for Vertical jump height (VJH) (p = 0.18), peak power output (PPO) (p = 0.18), and relative ground reaction force (rGRF) (p = 0.97)
There was a significant main effect for time for VJH (p < 0.001), PPO (p < 0.001), and rGRF (p = 0.01), where each individuals max jump from all whole-body vibration (WBV) conditions was greater than the control condition (Figure 1), no significant (p > 0.05)

Summary

Introduction

It is common to use traditional training techniques, such as strength training, plyometrics, and weightlifting and it may be beneficial to incorporate non-traditional techniques to further enhance performance [1,2,3]. It has become increasingly popular to incorporate non-traditional training modalities such as, whole-body vibration (WBV) [4,5,6,7,8] to achieve performance enhancement. Previous research indicates WBV exposure at a moderate intensity is safe and effective in stimulating the neuromuscular system [4] and has been shown to induce non-voluntary muscle contractions [17]. Power output is a key variable for sports performance and previous research have shown an increase in power production by facilitation of an explosive strength effort [9,18,19]
