Abbreviations: WBV = whole body vibration training group, C = control group, CMJ = countermovement jump, NJ = number of jumps performed in the 30 s continuous vertical jumping test, AH = mean height of jumps performed in the 30 s continuous vertical jumping test, AP = mean power of jumps performed in the 30 s continuous vertical jumping test.

* Significantly different from Pre test (p < 0.05) as determined by repeated measures analysis of variance and post-hoc Tukey tests.
