Effects of Whole Body Vibration Exercise on Lower Extremity Muscle Activity and Balance Ability in Football Player with Chronic Ankle Instability

ABSTRACT

PURPOSE: The purpose of this study was to determine the effects of whole body vibration exercise (WBVE) on lower extremity muscle activity and balance ability according to different methods of exercises in football player and use it as basic data for the rehabilitation training of chronic ankle instability. METHODS: Thirty subjects were randomly divided into two groups the two groups, which each group have 15 members, are WBVE group and neuromuscular training (NMT) group according to training method. The exercise program was conducted for six weeks. Subjects were measured on lower extremity muscle activity and balance ability. RESULTS: The muscle activity increasement of the WBVE group was significantly higher than that of the NMT group (p < 0.05) and the balance ability decreasement of the WBVE group was significantly higher than that of the NMT group (p < 0.05). CONCLUSION: These findings of this study suggest that WBVE may have a beneficial effect on improvement of lower extremity muscle activity and balance ability in football player with chronic ankle instability.
