原地推铅球是历年来体育高考项目之一,都知道技术动作是追求优异成绩的前提。但在强调技术时,不少教练员仅注重下肢和投掷臂的动作,而忽略了非投掷臂。笔者在长期的教学与训练实践中发现,正确地理解和运用非投掷臂(以左臂为例),能够很好地形成爆发式的投掷动作,对保持正确的出手角度与方向以及最后用力等均有重要的作用。 Putting a shot in place is one of the sports college entrance examination programs over the years and all know that technical actions are the prerequisite for pursuing outstanding achievements. However, in emphasizing technology, many coaches focus only on the movements of lower limbs and throwing arms while ignoring non-throwing arms. The author in the long-term teaching and training practice found that the correct understanding and use of non-throwing arm (to the left arm, for example), can well form a burst of throwing action to maintain the correct shot angle and direction and the last force Have an important role.
