Abstract

The objective of this study was to assess the acute effect of different intensities of whole body vibration (WBV) on muscle performance. 8 recreationally trained males were randomly subjected to one of 3 experimental conditions: (A) WBV 2 mm [45 Hz and 2 mm], (B) WBV 4 mm [45 Hz and 4 mm], and (C) no WBV. To assess PAP, the peak concentric torque of knee flexors and extensors was measured during a set of 3 unilateral knee flexor-extensions at 60°/s−1 in an isokinetic dynamometer. The power output and height during vertical jumps were also evaluated. These measurements were performed both before and after the experimental conditions and then compared. Comparing the knee flexion data from the conditions with and without WBV indicate that WBV potentiated the peak torque during unilateral knee flexion in the isokinetic test (p<0.05). In addition, the power output (p=0.01) and vertical height of jump (p=0.03) were also potentiated by WBV. However, increasing the vibratory stimulus did not further potentiate the results. Thus, it is suggested that WBV be used before explosive events competition because WBV promotes post-activation potentiation.
