摘　　要：以我国女子铁饼运动员马雪君为研究对象,主要运用专家访谈法、生物力学测试法和数理统计法对她的运动技术特征进行分析,结果发现双支撑起转时间短于前3名优秀运动员,铁饼速度变化大,右脚离地时刻拉引角和肩髋角都大于前3名优秀运动员;单支撑旋转阶段时间长于前3名优秀运动员,旋转速度和速度提高小于前3名优秀运动员,拉引角和肩髋角大;腾空阶段时间长于前3名优秀运动员,平均速度和右脚着地速度小,铁饼行程大;转换时间短于世界优秀运动员,速度损失大;最后用力阶段时间短,两脚距离和铁饼行程短,旋转半径不足;躯干右侧速度都大于前3名运动员,左侧运动速度小于前3名运动员,左侧相对由侧运动不足。研究结论为,马雪君双支撑起转阶段时间短,用力早,上肢伸展幅度大,运动速度快,旋转半径小,躯干扭紧状态好,起转速度低;单支撑旋转阶段时间长,旋转速度慢,动作幅度大,左臂打开早;腾空阶段时间长,向前速度慢,做功距离大,速度损失大,着地身体重心姿势低,保持身体姿势的能力强;转换时间短、转换快,速度损失大,运动速度慢,上肢伸展幅度大,躯干扭紧不足;最后用力阶段时间短,动作速度快,工作距离短,出手角度小,出手高度低。In this paper, the methods of expert interviews, bio - mechanical testing and mathematical statistics was applied to study on Xue -Jun Ma discus throwing technique The Result is as the following： time is longer than pre -3rd athlete ,rotation and enhance velocity is lower than pre -3rd athlete double supporting; discus velocity change large, and the angle of shoulderhop and strength is bigger than pre -3rd athletes during single supporting; time is smaller than pre- 3rd athlete, rotation and enhance velocity is lower than pre -3rd athlete during double supporting; discus velocity; the angle of shoulder - hop and strength is bigger than pre - 3rd athletes during fling stage; time is longer than pre - 3rd athlete , discus of average velocity and right foot leave velocity is lower than pre -3rd athlete, discus work distance is longer during fling stage and time is smaller world athletes, the damage of discus velocity is big during transition stage, distance of double foot supporting and discus is small, rotation radium is short and movement velocity of the torso left is lower than pre - 3rd athlete and right is lower than pre -3rd athlete during final stage. The main conclusion as follows ：time is short, strengthen too early and arm swing large. Movement velocity is fast, rotational radius is small, torso twist is strange during double supporting; Start rotation time is short, rotational velocity is lower, movement rang is large, working distance is longer velocity is lower; left army stretch early and ability to keep body figure is poor during single supporting; forwarding velocity is lower and working distance is longer, time long and velocity lose ratios higher and BG landing lower during fling stage and transition stage; time is small, transition fast and velocity lose lager, working routine short and velocity lower flying angle is small and height is lower; suggested shorten rotation swing, fasten movement and strength torso muscle.
