对1992年巴塞罗那奥运会上335名男子和女子游泳运动员在50米、100米和200米自由泳比赛中的表现进行录像和分析，以确定泳长（SL）、泳率（SR）、出发时间（ST）、转弯时间（M =转入，to =转出）、结束时间（ET）和平均速度（AV）；然后确定这些变量与身高、体重、年龄和死亡时间（FT）之间的关系。随后对项目内部和项目之间的差异进行了评估，并对男性和女性的表现进行了比较。ST， TI， TO， ET和SL被确定为在每个距离成功游泳的主要组成部分。结果显示，所有事件的因素之间存在统计学上显著的相关性。这些人年纪大了，个子高了，笔划也长了；他起跳，转身，游得比女人还快。随着比赛距离从50米增加到200米，男性和女性的ST、TI、to、SL和ET均增加，而年龄、SR和AV则减少。
The performances of 335 male and female swimmers competing in 50-, 100-, and 200-m freestyle events at the 1992 Barcelona Olympic Games were videotaped and analyzed to determine stroke length (SL), stroke rate (SR), starting time (ST), turning times M = turn in, TO = turn out), finishing (end) time (ET), and average velocity (AV); relationships were then determined among these variables in addition to height, weight, age, and final time (FT). Differences were subsequently assessed within and among the events, and comparisons were made between male and female performances. ST, TI, TO, ET, and SL were identified as principal components of successful swimming performance at each distance. Results revealed statistically significant correlations between factors for all events. The men were older and taller, possessed longer stroke lengths; and started, turned, and swam faster than the women. As the race distance increased from 50 to 200 m, ST, TI, TO, SL, and ET increased for both men and women, while age, SR, and AV decreased.
