Athletes' times in 200-m indoor races are greater than in outdoor races. The purpose of this study was to determine which 50-m sections were slower indoors than outdoors in 200-m sprint events and by how much. Using 2-dimensional photogrammetric techniques, a 50-m split-time analysis was made of the performance of 17 men and 16 women, all well-trained athletes, at 4 national competitions held over 5 years. The time taken to run the 0- to 50-m section was longer indoors than outdoors in women (6.89 ± 0.12 vs. 6.75 ± 0.04 seconds; p < 0.05) and in men (6.18 ± 0.10 vs. 6.08 ± 0.09 seconds; p < 0.05). Similarly, both women and men took more time to run the 100- to 150-m section indoors (6.03 ± 0.15 vs. 5.84 ± 0.06 seconds; p < 0.01, respectively) than outdoors (5.26 ± 0.15 vs. 5.06 ± 0.07 seconds; p < 0.01, respectively). Both sections indoors were run mostly on the curve. However, significant differences were not found in the split times for 50-100 and 150-200 m in either sex. In both categories, the relative average velocity (RAV), percentage of average velocity relative to the maximum velocity reached in the fastest section (50-100 m), was about 3% lower indoors than outdoors in 100- to 150-m section. The athletes' lower capacity to develop speed indoors could be caused specifically, by the curved 0- to 50-m and 100- to 150-m sections of the indoor track. Coaches could use these data as reference values there being few published data from high-level competitions. The RAV could be used by coaches to compare results among athletes of different levels and sexes.
运动员在 200 米室内比赛中的用时大于室外比赛。本研究的目的是确定在 200 米短跑比赛中，哪 50 米分段在室内比室外慢，以及慢了多少。使用二维摄影测量技术，对 17 名男性和 16 名女性运动员在 5 年内 4 次全国比赛中的表现进行了 50 米分段时间分析。这些运动员都是训练有素的优秀运动员。结果发现，女性运动员在 0 到 50 米分段的用时，室内比室外长（6.89 ± 0.12 秒比 6.75 ± 0.04 秒；p < 0.05），男性运动员在 0 到 50 米分段的用时，室内比室外长（6.18 ± 0.10 秒比 6.08 ± 0.09 秒；p < 0.05）。同样，女性和男性运动员在 100 到 150 米分段的室内用时都比室外长（6.03 ± 0.15 秒比 5.84 ± 0.06 秒；分别为 p < 0.01），5.26 ± 0.15 秒比 5.06 ± 0.07 秒；分别为 p < 0.01）。两个分段在室内都主要在弯道上进行。然而，在男女运动员的 50-100 和 150-200 米分段时间上，并没有发现显著差异。在这两个类别中，相对平均速度（RAV），即 100-150 米分段的平均速度相对于最快分段（50-100 米）达到的最大速度的百分比，在室内比室外低约 3%。运动员在室内的速度发展能力较低，可能是由于室内跑道的 0 到 50 米和 100 到 150 米的弯道造成的。教练可以将这些数据作为参考值，因为在高水平比赛中很少有公布的数据。RAV 可以被教练用来比较不同水平和性别的运动员的成绩。
