| 摘 要： | 应用阻力与速度的平方成正比定律1]2],审视在竞赛速度条件下游泳体位与打腿配合技术。认为身体水中姿态与打腿技术的合理性与否在于通过技术动作所产生的推进阻力纯值的大小来给予评价。以此为依据,提出在竞赛条件下,游泳体位姿态与打腿配合技术相关的两种新技术观点:对水中人体姿态流线型的新诠释;快频率、小幅度打腿技术在竞赛速度条件下对水中游泳体位的影响。

Discuss the trend of alteration on the swimming kick technique and body position in the condition of the race speed |
| |
| Abstract: | Based on the law of physicles about that the drag goes up by square as the increase speed of an object moving through water, examining tetails the trend of alteration on the swimming kick and body positioning in the race speed condition, the paper finds out that the result should bevalued by the net forward force of propulsive drag that produced by the athletes when the swim under the race speed. In accordance with the views above which is benefited to the athletes race speed, two kind of viewpoints concerning with body position and kick technique were raised in the paper, Frist, a new interpretation on the streamline body position during race speed. Second,the effect about the smaller and quick kick technique which has a positive benefit to the athletes when they swim during the race speed. |
