Purposes: Analysis of the Chinese women's shot player Xiangrong LIU 2016 national track and field throwing group race (Xipu station) champion throwing action, revealing the law of shot put. Procedures: Application data engineering method - with two JVC GC-PX10AC cameras were placed in the direction of throwing and positive right, two cameras, the main axis of the angle of about 90°, shooting frequency of 50Hz. Using Signal TEC 3D software to analyze the kinematic parameters. Methods: Three - dimensional video analysis method. Result: The study of kinematic parameters refinement, the whole throw is divided into five times, four stages. Conclusions: Pre-swing acceleration, sliding step, buffer the three stages of the center of gravity speed, shot speed are improved. The last stage of force, the center of gravity velocity decreased, the shot speed increased. T4 moment shoulder hip angle of 109.5°, "beyond the device" is better; T5 time shot speed 12.5 m/s to be improved, shot height 1.97m reasonable, shot angle 35.89 ° smaller.
