田径基本技术原理教学探讨

Teaching of track and field basic techniques

跑、跳跃和投掷是田径运动中的基本技术。支撑反作用力是影响跑速的最重要因素,分析了跑的动力来源及增效途径,跑的阻力来源及其消减途径。跳跃技术中助跑最后4步技术直接影响起跳效果,分析了起跳的技术要素。最后用力技术是投掷技术中的基础,同时,最后用力前的姿势也不容忽视。

Running,jumping and throwing are the basic techniques in track and field. Supporting reaction is the most important factor influencing the speed of running. This paper analyzes source of power and ways of its promotion as well as source of resistance and ways of its reduction. The last four step techniques of approach run in jumping directly influence the results of jumping. Techniques of last exertion are the bases of the throwing techniques. Meanwhile,the posture before the last exertion cannot be ignored.
