为保证推铅球动作的高难度,大多数学术研究认为应放松、自然、连贯、流畅,衔接紧密而用力结构简单、实用,能充分发挥技术的总体效应,但对最后用力阶段的划分却存在分歧,有的学术派认为最后用力始于左脚着地瞬间,有的学术派认为最后用力始于滑步结束后右脚着地积极蹬伸产生的向前的支撑反作用力,本人比较赞同后一种观点,并对此进行了分析、论证。
In order to ensure the difficulty of shooting the shot put, most academic researches think it should be relaxed, natural, coherent, smooth and closely connected. The force structure is simple and practical, which can give full play to the overall effect of technology. However, there are differences in the division of the last effort period Some academics think the last force began to move left foot to the moment, and some academic that the final force began after the slide after the right foot to actively push forward stretch support forward force, I quite agree with the latter point of view , And analyzed and argued this.
