摘要

目的:本研究的目的是阐明60米短跑中单独跑(单独条件:AC)和并排跑(竞争条件:CC)两种不同条件下短跑成绩的差异。方法:以26名男大学生短跑运动员为研究对象。他们被要求完成两个60米冲刺,AC和CC,从蹲起,以最大的努力。运行时空变量由两台数字高速摄像机拍摄的视频图像获得。结果:在最大速度段(30 ~ 60m), CC组的跑速(AC: 9.34±0.45 μ m -1 vs CC: 9.40±0.43 μ m -1, p = 0.011)和步长(AC: 2.04±0.12 m vs CC: 2.06±0.10 m, p = 0.021)显著增加,但步频(AC: 4.58±0.26 Hz vs CC: 4.57±0.27 Hz, p = 0.595)差异无统计学意义。加速度段(0-30m)各变量无显著差异。结论:与竞争对手一起跑步在最大速度段随着步长的增加而提高跑步速度,但在加速段不影响成绩。我们的结论是,在最大速度部分,比赛可以提高短跑成绩。

Competing against another athlete side-by-side improves 60 m sprint running performance
Purpose: Purpose of this study was to elucidate the differences in sprint performance between two different conditions in the 60 m dash: subjects ran alone (Alone Condition: AC) or two runners competed side-by-side (Competitive Condition: CC). Methods: Subjects were twenty-six male university sprinters. They were asked to perform two 60 m dash, the AC and CC, with maximal effort from crouching start. Running spatiotemporal variables were obtained from video images taken with two digital high-speed cameras. Results: Running speed (AC: 9.34 ± 0.45 mžs-1 vs CC: 9.40 ± 0.43 mžs-1, p = .011) and step length (AC: 2.04 ± 0.12 m vs CC: 2.06 ± 0.10 m, p = .021) in the maximal speed section (30-60m) were significantly increased in the CC. However, there was no significant difference in step frequency (AC: 4.58 ± 0.26 Hz vs CC: 4.57 ± 0.27 Hz, p = .595). There was no significant difference in any variables in the acceleration section (0-30m). Conclusion: These results indicate that running with a competitor improves running speed with increasing step length in the maximal speed section but does not affect performance in the acceleration section. We concluded that competition improves sprint performances in the maximal speed section.
