BACKGROUND: The purposes of this study were to analyze the impact of 24 weeks of vibratory and multi-component training and to determine what type of training creates greater adaptations on body composition, and isokinetic strength of the knee and ankle joints in postmenopausal women.

METHODS: Thirty-eight women (60.0 ± 6.3 years) were randomly assigned to whole body vibration group (WBVG), multi-component training group (MTG), or a control group (CG).

RESULTS: A significant decrease was observed in total fat mass in experimental groups. WBVG and MTG showed significant increases in isokinetic strength for knee extensors at 60º·s-1 and at 270º·s-1. Regarding ankle joint, there were significant increments for plantar flexion at 60º·s-1 in WBVG and at 120º·s-1 in the two trainings groups. MTG showed a significant increase for dorsiflexion at 60º·s-1. With respect eversion and inversion, WBVG and MTG improved isokinetic strength at 60º·s-1. For eversion at 120º·s-1 increased in WBVG and for inversion at 120º·s-1 in WBVG and MTG.

CONCLUSIONS: 24 weeks of whole body vibration or multi-component trainings result in positive modifications in total fat mass. These trainings are efficient to improve knee-extension and stabilizer muscles of the ankle joint strength.
