| 摘要: |
| 采用文献资料法、数理统计法和测试法，观察10名一级以上短距离自由游泳运动员在接受高频速划训练后的比赛表现，并追踪其100米与200米自由泳成绩。结果显示，其成绩分别提高了9%和71%。成绩有所提高的高频速划训练组，在游泳时能量消耗量减少了20%，这与划水频率—速度关系改变有关。研究认为，采用基于划水频率—速度关系的高频快速划训练计划，可以提高自由游泳运动员的能量代谢水平，最终能在不经过陆上训练、超长距离训练或赛前减量的情况下提高游泳成绩 |

| Abstract: |
| Using literature review, mathematical statistics and test method, this study observes the competition performance after training of high frequency and fast stroke of ten shortdistance swimming athletes above first grade sportsman, and keeps track of their competition performances in 100meter and 200meters freestyle swimming. The results shows that their performances have increased by 9% and 71% respectively. In the group of high frequency and fast stroke which has got a better performance, energy consumption has reduced by 20%, and this is linked with the changes in the relationship of stroke frequency and speed. This study suggests that the training plan of high frequency and fast stroke based on stroke frequencyspeed relationship can improve the energy metabolic level of free swimming athletes, eventually improve the swimming performance without training on land, long distance training and training reduction before competition. |
