摘要
使用索尼PD190型摄像机对5名不同水平男子背向滑步推铅球选手最后用力时躯干运动时空进行摄像,并进行图像解析后的生物力学分析。分析表明:5名运动员的躯干运动是在进行前振的同时伴随有序的一种复合运动;肩与髋轴转动角度与转动速度的变化随着他们所处在不同时相而存在明显区别。
Two Sony PD190 cameras were used to shoot the space-time of the trunk movements in the final exertion of 5 male backward sliding-step shot-putters at different levels,and biomechanical analyses were made after image analyses.The conclusion shows that the trunk movements in the final phase of the 5 shot-putters are composite motions with forward vibration and orderly rotation at the same time,and there are obvious differences in the changes of shoulder and hip axis rotation angle and rotation speed at different phases.
