本研究旨在比较国家级与地区级游泳选手出发与转身阶段的比赛特征。在这项研究中，100和200米的事件进行了分析，在公开赛科穆尼达德马德里（西班牙）锦标赛的决赛阶段。采用“个体化距离”法和二维直接线性变换算法进行种族分析。国家级游泳运动员在所有比赛段和划水比较中获得了更快的速度，尽管在分析的事件中只有一半（16个中的8个）获得了开始速度的显着水平间差异。高水平的游泳运动员也有较长的出发和转身距离，但仅限于速度增益高的比赛段。这在转身段、仰泳和蝶泳以及200米蛙泳项目中观察到，但在任何自由泳项目中都没有观察到。由于水下分段的适当延长而导致的时间改善似乎对最终比赛的结果至关重要，应该通过“个性化距离”方法进行仔细评估。
The aim of this study was to compare the race characteristics of the start and turn segments of national and regional level swimmers. In the study, 100 and 200-m events were analysed during the finals session of the Open Comunidad de Madrid (Spain) tournament. The "individualized-distance" method with two-dimensional direct linear transformation algorithm was used to perform race analyses. National level swimmers obtained faster velocities in all race segments and stroke comparisons, although significant inter-level differences in start velocity were only obtained in half (8 out of 16) of the analysed events. Higher level swimmers also travelled for longer start and turn distances but only in the race segments where the gain of speed was high. This was observed in the turn segments, in the backstroke and butterfly strokes and during the 200-m breaststroke event, but not in any of the freestyle events. Time improvements due to the appropriate extension of the underwater subsections appeared to be critical for the end race result and should be carefully evaluated by the "individualized-distance" method.
