本研究的主要目的是：（1）检查在开始和转弯段的水下行进距离与游泳比赛成绩之间的关系，在精英水平和（2）以确定是否个性化的距离开始和转弯参数影响整体的比赛成绩。采用创新的图像处理系统InThePool（（R））2.0对2013年世界田径锦标赛100米和200米项目的比赛参数进行了测量。总的来说，100米比赛时间在很大程度上与男子蛙泳和自由泳比赛中更快的起步速度有关。相反，总体而言，200米比赛时间在很大程度上与女子蝶泳比赛中较长的出发距离，男子和女子仰泳和女子蝶泳比赛中较长的转身距离以及女子自由泳比赛中较短的转身距离有关。在大多数100米项目中，出发或转身速度的变化可以代表适度的时间改进，而出发或转身距离的修改（特别是在最后一个转身）可以为优秀游泳运动员提供200米项目中具有实际重要性的时间改进。应向优秀游泳运动员提供通过个性化距离参数对比赛的评估，以便为每个项目决定最合适的比赛分段配置。
The main objectives of the present research were (1) to examine the relationships between the distances travelled underwater during the start and turn segments with swimming race performance at the elite level and (2) to determine if the individualised-distance start and turn parameters affect the overall race performance. The race parameters of the 100 and 200m events during 2013 World Championships were measured by an innovative image-processing system (InThePool((R)) 2.0). Overall, 100m race times were largely related to faster start velocities in men's breaststroke and freestyle events. Conversely, overall, 200m race times were largely related to longer starting distances in the women's butterfly events, to longer turn distances in men's and women's backstroke and women's butterfly events and to shorter turn distances in women's freestyle events. Changes on the start or turn velocities could represent moderate time improvements in most of the 100m events, whereas modifications on the start or turn distances (especially in the last turn) could provide elite swimmers with time improvements of practical importance on the 200m events. The evaluation of races by individualised-distance parameters should be provided to elite swimmers in order to decide the most appropriate race segment configuration for each event.
