Purpose: This study was aimed to examine the acute effect of whole body vibration training (WBVT) on the reaction time, movement time and explosive power of four kicks for taekwondo (TKD) athletes. Methods: So far, four female TKD athletes were recruited. Kicking performances including roundhouse kick (RK), axe kick (AK), back kick (BK), back spinning kick (BSK) ,were conducted before and immediately after whole body vibration (WBV). For imitating duration of the contest, three rounds of two minutes with one minute of rest between rounds on a seat. Vibration frequency was set 30Hz, and amplitude was seven mm. The reaction time between beginning of target moving and onset of kicking, movement time defined time difference between onset of kicking and hitting the target, as well as explosive kicking power were detected by accelerometers attached on kicking leg and target. Nonparametric test was used to examine the difference between pre and post whole body vibration training. Results: There was no significant difference on reaction time between pre and post WBVT. However, movement time of RK, AX, and BK was shorter and the kick power of RK and BK was greater after WBV. Conclusion: There was an immediately tread of progress in kick movement time and power performance after the WBV. Hopefully, WBV will be applied on TKD training in the further.
