摘要
文章运用牛顿定律、运动的独立性等力学原理,对影响推铅球远度的因素进行了全面的理论分析.采用建立数学模型的方法,通过对各因素在推铅球中的作用进行理论计算、对比分析和验证,使运动员和教练员可以全面、准确了解各因素对推铅球成绩的影响以及它们之间的相互关系,从而对运动训练起到指导作用.
Using Newton＇s law and sport independence equal- mechanics theorem, this article analyzed and studied on the influencing factors of shot putting. Though establishing mathematical model, the effects of every factors on the performance of shot putting were analyzed and authenticated. The paper is helpful for athletes and coaches to properly understanding the effects of every factors on the performance of shot putting. , thereby directing the exercise training.
