FOOT PRESSURE STUDY DURING PULLING PHASE OF SNATCH LIFTING
Keywords: foot pressure, snatch lifting
AbstractThe feet act as a supporting base during the snatch lifting. Four weightlifters participated in the study in order to understand the mechanism of the applying force. The PEAK 5 video analysis system and the EMED Pedar insole system were used. Results revealed no significant differences (P<. 05) between the force-peaks of the foot. In phase 1, COP moved backward to the center of the foot to assist lifters maintain equilibrium. In Phase 2, the “double knee bend” technique helps barbell to obtain sufficient velocity. The Forefoot Area bear the maximal force in Phase 3 and significant correlation (P<. 01) was found between the FA force-time integral and the barbel l impulse in Phase 3. Also, the ankle plantar flexed causing the COP to move forward to increase barbell velocity in phase 3.
