The Effects of Acute Whole Body Vibration Exercise For Warm-up

The purpose of this study was attempted to quantify the acute effect of intermittent whole body vibration exercise for the effects of warm-up. The subjects of this study were 20 university students were participated. Subjects performed 6 set of vibration exercise that have 1 min vibration exercise(40Hz, ±5mm) and 2min rest, maintaining an half-squat position on vibratory platform. vertical jump and whole body reaction time test were administered before and after each vibration exercises. One-way analysys of variance(ANOVA) were performed to see the differences of jump height and reaction time between pre and post exercise sets. The result showed an increase(not significant) in vertical jump height when exercise time was further, and maximum height was found at after 5set. After 3 or 4set vibration exercise Significantly higher than pre(p.001), and over 5 or 6set were none. The results indicated that whole body vibration may be a potential warm-up procedure for increasing vertical jump height and whole body reaction time, but optimum exercise time were important factor. Future research is warranted addressing the influence of various protocols of duration and frequency on whole-body vibration exercise.
