本研究的目的是通过比较2004年雅典奥运会半决赛选手（n=64）和2004年法国全国锦标赛半决赛选手（n = 64），评估优秀女子游泳运动员（200米项目，所有四种技术）的划水率变异性。由于游泳速度（V）是划水速度（SR）和划水长度（SL）的乘积，因此确定了这三个变量以及第一和第二百米的划水速度变异系数（CVSR（V1，V2; SR 1，SR 2; SL 1，SL 2; CV（SR）1，CV（SR）2）并计算两部分事件之间的差异（Delta V; Delta SR; Delta SL; Delta CVSR）。当对四个200米项目的结果进行分析时，SR 1、SR 2、SL 1和SL 2较高（α =0.05，P
The aim of this study was to assess stroke rate variability in elite female swimmers (200-m events, all four techniques) by comparing the semi-finalists at the Athens 2004 Olympic Games (n=64) and semi-finalists at the French National 2004 Championship (n=64). Since swimming speed (V) is the product of stroke rate (SR) and stroke length (SL), these three variables and the coefficient of variation of stroke rate (CVSR) of the first and second 100m were determined (V1, V2; SR1, SR2; SL1, SL2; CV(SR)1, CV(SR)2) and differences between the two parts of the events were calculated (Delta V; Delta SR; Delta SL; Delta CVSR). When the results for the four 200-m events were analysed together, SR1, SR2, SL1, and SL2 were higher (alpha=0.05, P
