Whole-body vibration training has exercises perform static and dynamic resistance training exercises on a ground-based platform. Exposure to WBV exposure has demonstrated benefits and no effect on lower body strength, power, and performance. The aim of this study was determine if WBV exposure (50 Hz, 2.51 mm) has any potentiating effects post-exercise by measuring the kinematic variables of a set of upper body elbow extensor exercise (70% one-repetition maximum [1RM]) to volitional exhaustion. Sixteen recreationally active students (12 males and 4 femaes) performed three different experimental conditions on separate days. Each condition has subject's perform on set of elbow-extension exercise to fatigue with one of three WBV treatments: WBV simultaneously during the set (AE); 60s after application of WBV for 30s (RE); and no WBV (CTRL). Kinematic parameters of each repition were monitored by linking a rotary encoder to the highest load plate. Mean velocity and acceleration throughout the set, as well as perceived exertion was analyzed. A significant increase (p<0.05) was observed in the mean velocity for the whole set in AE condition versus the CTRL condition. The mean acceleration was significantly higher (p < 0.05) in AE condition in comparison to RE (increased by 45.3%) and CTRL (increased by 50.4%) conditions. The positive effect indued by WBV on upper limb performance is only achieved when the stimulus is applied during the exercise. However, WBV aplpied 60s prior to the upper body exercise results in no benefit.
