Department HPERD, University of Idaho, College of Education, Human Performance Laboratory, Moscow, ID  83844, USA. ddolny@uidaho.edu  In recent years, it has been suggested that exercise using whole body vibration (WBV) platforms may  increase muscle activity and subsequently enhance muscle performance in both acute and chronic  conditions. WBV platforms produce frequencies ranging from 15-60 Hz and vertical displacements from  ~1-11 mm, resulting in accelerations of ~2.2-5.1 g. Acute exposure to WBV has produced mixed results  in terms of improving jump, sprint, and measures of muscle performance. With WBV training, younger fit  subjects may not experience gains unless some type of external load is added to WBV exercise.   However, sedentary and elderly individuals have demonstrated significant gains in most measures of  muscle performance, similar with comparable traditional resistance exercise training programs. WBV  training also has demonstrated gains in flexibility in younger athletic populations and gains or  maintenance in bone mineral density in postmenopausal women. These promising results await further  research to establish preferred WBV training parameters.
