| 摘 要： | 研究目的：通过对黄东祎技术动作最后用力环节的运动学分析，得出其动作的优化途径，为今后训练突破提供理论依据和数据支持。研究方法：使用三维红外运动捕捉系统，对采集成功（无犯规）的3次技术动作进行解析，并使用Visual3D软件计算出受试者的运动学相关参数。研究结果：黄东祎与国内外男子优秀铁饼运动员相比，其投掷铁饼最后用力阶段铁饼的运动距离均显示较短；在单支撑阶段及双支撑阶段，黄东祎投掷动作的铁饼运行距离都小于国内外优秀运动员。研究结论：黄东祎投掷铁饼第二圈旋转动作中，下肢用力顺序基本符合训练要求，手臂与躯干的扭紧程度尚可；存在整体动作幅度较小，躯干扭紧程度不够，右髋关节活动度较左髋关节小。建议在今后的训练中应加强黄东祎在第二圈旋转动作中髋横轴旋转能力；同时注重加强右髋关节用力的积极性，从而优化双支撑阶段的身体扭转，增加动作的幅度。

| Abstract: | Objective: This study attempts to make a kinematic analysis of Huang Dongyi''s final force-exertion movement so as to find ways for optimizing his movement and provide theoretical base and data for the future breakthrough in training. Method: The three technical movements captured successfully (without fouls) will be analyzed by the 3D motion capture system and Visual 3D will be used to calculate the related kinematic parameters of the subject. Result: Compared to other domestic and foreign male discus throwers, the moving distance of the discus thrown by Huang Dongyi in the last exertion phase is shorter. Similar phenomena can be seen in the single support and double support phases. Conclusion: In the 2nd round turning movement, the sequence of his lower leg exertion basically conforms to the training requirements. The strain of his arms and body is relatively OK. The deficiencies of his movements lie in the small range of the whole motion, the lower strain degree of the body and the smaller movement range of the right hip joint compared to that of the left hip joint. The paper suggests that the turning ability of Huang Dongyi''s hip transverse in the second round of the turning movement should be improved in future training. The positiveness of the exertion of the right hip joint should be strengthened. As a result, the turning of the body in the double support phase can be optimized and the motion range can be enlarged. |
