“4×10米往返跑”属于短跑类教材,又不同于短跑,短跑的速度取决于步长和步频两个因素,而往返跑单单有速度是无法取得好成绩的,有速度还得有往返跑的技术动作。往返跑的技术动作中又以转身动作为重点,往返跑的最终成绩也取决于3个转身动作,转身动作做不好,速度再快也徒然。本文采用实验对比法,就转身动作对提高“4×10米往返跑”成绩进行探析。结果显示,加强转身动作的训练,可使“4×10米往返跑”成绩在1～2个月内大幅度提高。
“4x10 m round-trip run ” belong to the sprint teaching materials, but also different from the sprint, the speed of the sprint depends on the step and the pace of two factors, and the speed of the return trip alone can not get good grades, Have to run back and forth from the technical action. Return to the technical action and turn to focus on the action, the final result of the round-trip run also depends on the three turn action, turn around and do a good job, fast again in vain. In this paper, the experimental contrast method, to turn action to improve “4 × 10 m round-trip run” results for exploration. The results show that strengthening the turn movement training, can make “4 × 10 m round-trip run” results in 1 to 2 months significantly improved.
