The purpose of this study was to evaluate thigh muscle activities during WBV exercise with different squat position.
Ten healthy women performed four squat posture on a vibration platform such as LS, HS, HU&HS and OS. Surface electromyography signals thigh muscles were taken and analyzed. A vibration stimulus is 25Hz and intensity is 4mm. Muscle activities during WBV were compare d with no WBV.
In the result, EMG signals caused by WBV were significantly increase(P<0.05) compared with no WBV in all thigh muscles and various squat positions.
In conclusion, WBV would have an effect on increasing activation of the thigh muscles.
