文章运用文献资料法、实验法的研究方法,依据运动生物力学的基本原理、运动技能形成及迁移规律、教学与训练的循序渐进原则,通过使用逐渐增加重量的铅球代替单一重量的铅球进行铅球教学实验,得出通过铅球重量的变化调节推铅球的难度,提高学生对背向滑步推铅球技术的掌握程度这一方法具有可行性及有效性,丰富现有的推铅球教学训练理论与方法。
Based on the basic principles of sports biomechanics, the formation and migration of sports skills and the gradual and orderly principle of teaching and training, this paper uses the method of literature review and experiment to carry out the shot-put teaching experiment by using the incremental weight of shot put instead of a single shot , It is feasible and effective to adjust the difficulty of shooting the shot put by the change of shot weight and improve the students’ mastery of the back-skating shot-putting technique, and to enrich the existing theory and method of shot put teaching.
