掷铁饼属于非周期性动作,是由几个不同的单一动作结合起来,构成一个完整的动作.其中,“最后用力”是掷铁饼完整技术最重要的组成部分.“最后用力”动作完成得好坏,对掷铁饼的运动成绩有决定性的影响,那么,如何才能保证在掷铁饼的“最后用力”阶段有最大的功能效应呢?这就不但要懂得完成掷铁饼“最后用力”技术表现出来的动作形式上的特点,而且还要清楚决定动作形式的诸力相互作用的关系和特点,才有助于揭示完成掷铁饼“最后用力”技术动作变化的情况和引起变化的原因,以利提高在掷铁饼时“最后用力”阶段的最大功能效应的发挥.在力矩的作用下,人体带动的铁饼完
Discus discus is a kind of non-periodic action, which is composed of several different single actions to form a complete action, in which “Last Force ” is the most important part of the complete discus discus technique “Last Force ” How well is it possible to guarantee the greatest functional effect in discus ’s “Last Forces” stage? This will not only be enough to know how to finish discus throwing “ Last force ”technology, but also to clearly determine the relationship between the forms of action and the relationship between the characteristics of the interaction, it will help reveal the completion of throwing discus “ Last Forces ”technical movements change situation And the causes of change, in order to enhance the maximum functional effect during discus throwing “the last force ” stage.Under the action of moment, the human-driven discus finished
