在田径运动中,推铅球是单手投掷的非周期性运动项目。推铅球时的技术方法与场地器械有其独特的特点,因而形成了独特的技术结构。推铅球同掷铁饼一样,都是在圆圈中投掷,左腿都有一个制动,支撑用力的动作,但是左腿用力是一个复杂的过程,而不仅仅是一个简单的动作形式,推铅球时,左腿在最后用力过程中,能否形成合球的支撑技术,对最后用力的效果影响极大。因此,本文就推铅球时如何优化运动技术结构,使之达到比较完善的效果,作一个初步探讨。 In track and field, putting shots is a one-handed throw of non-cyclical sports. The technical method of shooting a shot and the site equipment have their own unique features, thus forming a unique technical structure. Throw shots, like throw discus, are thrown in circles, with a brake on the left leg that supports hard action, but hard left leg exertion is a complex process, not just a simple form of action , The left leg in the last force in the process, the formation of co-support technology, the effect of the final force greatly affected. Therefore, in this paper, how to optimize the structure of sports technique when putting a shot put it to achieve a more perfect effect, make a preliminary discussion.
