摘　　要：采用问卷调查法对我国26名国家健将级男女铁饼运动员膝关节运动损伤进行调查,分别统计了运动员膝关节损伤的原因、损伤的性质及损伤发生的部位,了解铁饼运动员膝关节损伤的构成比。根据生物力学指标和运动员膝关节运动损伤情况,采用近景动态立体摄影的测量方法,用两台有电子快门的进口松下摄像机,对运动员现场比赛、训练进行定点拍摄,拍摄频率为50 Hz。采用爱捷运动录像快速反馈分析系统,进行图像采样和数据计算,用三维运动生物力学分析法,找出我国优铁饼运动员腾空和过渡阶段膝关节运动损伤原因。Investigated on the exercise trauma of keen joint for 26 discus throwers at master level in China with questionnaire, it recorded its reasons, characters and parts and realized the composing ratio of the trauma of knee joint. It shot the competition and training of throwers at locate by solid fixed shoot using two Panasonic vidicons with electronic shutter, with frequency of 50Hz, according to the parameters of biomchanics and the suiuation of trauma of knee joint. Sampled and calculated by sports kinescope speed feedback analysis system of Edias, it found out the reasons of exercise trauma of knee joint for elite discus throwers in flight and transit phaes by three dimension biomechanical analysis methods.
