现代100m跑技术中躯干稳固性研究

The Study On Stability Of Trunk In Modern Technique Of 100-meter Race

通过对现代100m跑动作技术分析,研究跑动中躯干、骨骼、肌肉的用力情况,进一步对四肢的灵活性与躯干的稳固性进行研究,揭示出躯干才是人体跑动的动力核心,短跑应该以脊柱为中心来带动肩带和髋关节的运动,同时应注意四肢各关节的灵活性等观点,为短跑的训练和理论的完善提供参考。

This paper analysed the technique of 100 - meter race and described the force stituation of limbs, skeleton and muscle during running, further studied the flexibility of limbs and the stability of trunk＇s affection on dash technology, some viewpoints can be refered： trunk is the power core of body moving, the dash should be with the focus on spinal column, leading the movement of pectoral girdle and thud, while the attention should be paid on each joint of four lambs flexibility. In the end ,several suggestions were given to offer the practical basis and theoretical direction for the sprint training.
