Linkage between acute whole body vibration and improvement of exercise performance

[[abstract]]Whole body vibration (WBV) is a widely used training tool to improve muscular performance. WBV has been reported to facilitate blood flow and muscle temperature, and making it to be a viable protocol of warm-up for subsequently physical activity. The aim of present study was to investigate acute bout WBV administration on quadriceps force performance. Eight participants completed three main warm-up modality in a randomized counterbalanced fashion, control, WBV (frequency: 30 Hz, amplitude: 2 mm) and bicycle ergometer (150 W, 100 rpm) for 1 min × 5 sets with 1-min rest interval, respectively. Assessments for the muscular force development were completed immediately after each warm-up session and the quadriceps strength, including peak torque, total work volume and fatigue index, was analyzed. There were no significant differences in peak torque, ratings of perceived exertion and total work volume among the three major groups. However, lower fatigue index was observed after administration of bicycle ergometer as a warm-up model when compared with the WBV and the control groups. Data of the present study illustrate that acute bout WBV (30 Hz, 2 mm) has no potentiation effects on muscular force development and anti-fatigue of quadriceps
