Two recent studies cast doubt on the merits of whole body vibration training, as either a replacement or an adjunct to conventional training, for improving jump performance.
Researchers from Springfield College in Massachusetts found that WBV training and conventional strength training had similar effects on jump performance in nine collegiate softball players. Each player completed a nine-week protocol that included three weeks of WBV training and three weeks of conventional strength training; the order of training was randomized.
No significant between-group differences were seen for standing long jump, vertical countermovement jump, or back squat performance. The findings were published in the September issue of the Journal of Strength and Conditioning Research.
In the second study, investigators from the University of Granada in Spain found that adding WBV to eight weeks of conventional resistance training had no significant effect on knee extensor strength in 29 young adults. Interestingly, however, body fat percentage significantly decreased in the WBV group only. Those findings were e-published in August by the European Journal of Applied Physiology.
