Rehabilitation Sciences Research Centre, University of Melbourne, Parkville, Victoria, Australia.  Erratum in: Med Sci Sports Exerc. 2009 Feb;41(2):482. INTRODUCTION: Whole-body vibration (WBV) has become a popular training method in recent  years. This study investigated the effect of WBV on the length-tension relationship of the ankle  dorsi- and plantarflexors as measured by a Biodex dynamometer (Biodex Medical Systems Inc,  Shirley, NY). METHODS: Twenty healthy young adult males participated in this study and were  exposed to two treatments. The first treatment (nonvibration) involved passive stretching of the  plantarflexors at end range of motion (ROM) for five 1-min bouts. The second treatment involved  the same passive stretch with superimposed WBV (frequency = 26 Hz) for five 1-min bouts on a  rotary vibration plate (Galileo 900; Novotec, Pforzheim, Germany). Voluntary ROM, peak torque, and  corresponding joint angle of the plantar- and dorsiflexors were recorded pre- and posttreatment.  Within-treatment (before and after) and between-treatment (WBV and nonvibration) outcomes were  assessed by repeated-measures MANOVA. RESULTS: No significant changes in the measures of  ankle dorsiflexion were found within or between treatments. No significant changes in the measures  of ankle plantarflexion were found after the nonvibration treatment. After WBV, however, there was  a significant 7.1 degree shift in the angle (P = 0.001) of peak plantarflexor torque production  corresponding to a longer muscle length.   CONCLUSION: This study shows that stretched human ankle plantarflexors respond to WBV by  generating peak voluntary torque at longer muscle lengths. This has possible benefits for the  rehabilitation of patients with neuromuscular disorders (e.g., stroke) who experience  short ankle flexor resting lengths.
