支撑腿技术对提高铅球成绩的教学实验研究

An Experiment Research on Support Leg Skill in Improving Shot put Performance

推铅球技术的关键是最后用力 ,而支撑腿技术又是整个环节中最重要的部分 ,支撑腿技术的好坏直接影响最后用力的效果。教学中我们发现大部分学生在推铅球最后用力时 ,支撑腿技术不够完善 ,影响推铅球的成绩。因此 ,在教学中应针对此问题 ,进行教学实验研究 ,做到有的放矢 ,使推铅球成绩得到明显提高。

The key of shot put is the strength put forth at last,and support leg skill is the most important part of the whole link. Support leg skill directly affects the effect of the strength put forth at last. We found it in our teaching that because support leg skill most students owned isnt perfect enough when they put forth their strength at last in their shot put,the results of shot put is not so good. Therefore,we should take aim at this problem in teaching and conduct teaching experiment research,which can make us have a definite object in view and the result of shot put can be obviously improved.
