Strength increase after whole-body vibration compared with resistance training
The aim of this study was to investigate and compare the effect of a 12-wk period of Whole Body Vibration training and resistance training on human knee-extensor strength. Sixty-seven untrained females participated in the study. The Whole Body Vibration group and the placebo group performed static and dynamic knee-extensor exercises on a vibration platform. Isometric and dynamic knee-extensor strength increased significantly in both the WBV group and the RES group, respectively, whereas the PL and CO group showed no significant increase. Counter-movement jump height enhanced significantly in the WBV group only. There was no effect of any of the interventions on maximal speed of movement, as measured by means of ballistic tests.Conclusion:
Whole Body Vibration, and the reflexive muscle contraction it provokes, has the potential to induce strength gain in knee extensors of previously untrained females to the same extent as resistance training at moderate intensity. It was clearly shown that strength increases after WBV training are not attributable to a placebo effect.
