大学生背向滑步推铅球出手技术的定量分析

Quantitative analysis of the college students' techniques of letting Go of the shot in putting the shot with the Steps slided Backwards

决定铅球成绩的因素有出手高度、出手速度、出手角度等方面。大学生的身体素质、运动能力与专业运动员相比有很大的差距 ,因此 ,对大学生背向滑步推球技术的评价不能采用专业运动员的标准。本文通过对 2 0名体育系学生背向滑步推铅球出手技术各项参数的统计分析 。

The factors determining the performance of the shot-put include the height,the speed and the angle of letting go of the shot in putting the shot. Since their physical qualities and athletic abilities have a long way to go to catch up with the professional sportmen,college sudents' techniques of putting the shot with the steps slided backwards should not be assessed according to the standards for the proffessional sportmen. Through the analysis of the statistics of all the parameters concerning the techniques of 20 students from the Physical Cuture Department putting the shot with the steps slided backwards, the paper dwells on the problems arising in the teaching of college students putting the shot with the steps slided backwards and their countermeasures and solutions.
