ABSTRACT
We made a 3D camera resolution on the elite Chinese weightlifting athlete Zhong Huang, with the three-dimensional analysis we gained the kinematic parameters and found the problem of his technique, thus provide some scientific basis for the weight-lift training. The results show that in the barbell lifting stage, the distance of Zhong Huang's hand is 69.6cm, a narrow grip and the depth of pre squatting is small. In the force stage, the angle of knee joint is relatively large, full squatting distance prolonging the working distance. In the squat support stage Zhong Huang had a good flexion of the hip and knee, in line with the "straight, stable, shallow" pre squatting requirements. In the stand up stage, Zhong Huang lifted the barbell and stood fast, which explains he had a good effect of force. In the jerk stage, he had an over bent of knee.
