Objective: This study aims to evaluate the relation between salivary concentrations of Cortisol (C), Testosterone (T), the ratio T:C and the individual performance of top-level female soccer athletes, during official matches. Method: Eighteen female athletes from a national soccer team (23.06 ± 4.33 years old) participated in the study. Four official matches were analyzed and the match time of each player, and the index of the individual effectiveness were calculated. Players were classified in two clusters according to the individual performance (cluster 1 – the weakest individual performance; cluster 2 – the highest individual performance) using K-means and a comparison on the hormonal variables were performed. Results: The players of cluster 2 generally revealed higher values (p˂0.05) in both positive actions and individual effectiveness, when compared with the players of cluster 1. The players of both clusters presented identical values of C, T and T:C at the four evaluated matches. The athletes of cluster 2 showed a significant increase of C (p˂0.05) and a significant decrease of T and T:C before the lost games (M2 and M5). However, there was no linear relation between the variation of both hormones during the match and the individual performance of players. Conclusion: Performance in competition revealed significant differences between players, though with no apparent relation to the hormonal kinetics of C and T before and after the matches.

优秀女子足球运动员唾液皮质醇和睾丸激素的含量。

目的：本研究旨在评估官方比赛中唾液中皮质醇（C），睾丸激素（T），T：C之比与顶级女足球运动员个人成绩之间的关系。方法：来自国家足球队的18名女运动员（23.06±4.33岁）参加了研究。分析了四场正式比赛，计算了每位球员的比赛时间和个人效能指数。使用K均值将运动员根据个人表现分为两个组（组1 –最弱的个人表现；组2 –最高个人表现），并对荷尔蒙变量进行比较。结果：第2类参与者通常在积极行动和个人效能上都显示出较高的值（p˂0.05），与组1的玩家进行比较时，两个组的玩家在四个已评估的比赛中都给出了相同的C，T和T：C值。第2组运动员在输掉比赛（M2和M5）之前，C值显着增加（p˂0.05），T和T：C显着下降。但是，比赛中两种激素的变化与运动员个人表现之间没有线性关系。结论：比赛中的表现显示出球员之间的显着差异，尽管与比赛前后C和T的激素动力学没有明显关系。05），在输掉比赛（M2和M5）之前，T和T：C显着下降。但是，比赛中两种激素的变化与运动员个人表现之间没有线性关系。结论：比赛中的表现显示出球员之间的显着差异，尽管与比赛前后C和T的激素动力学没有明显关系。05），在输掉比赛（M2和M5）之前，T和T：C显着下降。但是，比赛中两种激素的变化与运动员个人表现之间没有线性关系。结论：比赛中的表现显示出球员之间的显着差异，尽管与比赛前后C和T的激素动力学没有明显关系。
