一、完整概念和动力定型的培养 推铅球是属于非周期性动作的结合,由一系列不同的单一动作组成。由于每个动作是依次完成的,在动作结构上形成相对独立、复杂、连贯和稳定性。在练习过程中,神经支配要比周期性动作复杂得多。因此,在教学和训练过程中,首先应建立完整概念和直观感觉,通过讲解、示范、看图片、看录像等方式,使学生对铅球投掷有一个正确概念和形象思维。其次就是反复做徒手练习,通过做单一、小组合和完整动作,解决学生用力顺序、
First, the complete concept and the development of dynamic stereotypes Shot put is a combination of non-periodic action, by a series of different single action. Because each action is completed in turn, the formation of a relatively independent movement, complex, coherent and stability. During the exercise, the innervation is much more complicated than the periodic action. Therefore, in the teaching and training process, we should first establish a complete concept and intuition, by explaining, demonstrating, watching pictures, watching video, etc., so that students throw a correct concept and the image of thinking. The second is to do freehand practice repeatedly, by doing a single, a small group and a complete action to solve the student hard order,
