Abstract:
BACKGROUND: The biomechanical studies of ankle joint focus on methodology, and the biomechanical characteristics of the ankle joint under combined modes are little reported. OBJECTIVE: To analyze the kinematics and dynamics characteristics of the ankle joints in the movement of stop-jump of volleyball players. METHODS: Twenty male and 20 female volleyball players at Tianjin University of Sport were selected. The three-dimensional motion capture system (Vicon) and the three-dimensional force plate (Kistler) were mainly used to synchronously collect the kinematics and dynamics parameters of the ankle joint when the subjects were taking off and landing. Statistical methods were used to conduct comparative analysis of the data. The study was in accordance with the ethical requirements of Tianjin University of Sport, and the subjects signed the informed consents. RESULTS AND CONCLUSION: (1) Under this mode, the plantar flexion angle of the ankle joint in males was less than that in females. During the take-off phase, the ankle joint was in an inversion and internal rotation state, during the landing buffer phase, the ankle joint was in an inversion and external rotation state, and the angle in males was slightly larger than in the females, which was likely to cause ankle injury. (2) The three-dimensional peak torque and force value when stop-jump in males were higher than those in females. The appearing time of peak torque and force value in different directions in males was later than that in females, and imbalances between two legs and landing at different time occurred.
