对推铅球技术中左腿摆动动作的探讨

Study the Swing of Left Leg in the Shot Technology

滑步推铅球技术是田径项目中技术性很强的项目之一,本文采用文献综述法,根据生物学理论、力学原理和运动技术感受对滑步推铅球中一个局部环节(左腿的摆动)的细小差异进行分析。得出左腿的动作起着决定滑步方向、速度、重心的移动路线以及充分发挥力的效应等作用。对完善技术,提高运动成绩有着很重要的影响。

Sliding track and field shot put technique is one of the items in the highly technical, this article uses literature review method, according to biological theory, mechanics and sports technology, feelings of right slip shot put in a local part （left leg of the swing） and small differences in analysis. Come play a decisive moves his left leg sliding direction, speed, center of gravity of the mobile routes, and give full play to the role of technology. On improving technology to improve athletic performance has a significant impact.
