Abstract

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. Eighteen female athletes from a national soccer team (age 23.06 ± 4.33 years) participated in the study. Four official matches were analysed and the on-field time of each player as well as the index of individual effectiveness were calculated. Players were classified in two clusters according to their individual performance (cluster 1 – poor individual performance; cluster 2 – good individual performance) using K-means and their hormonal variables were compared. The players of cluster 2 generally revealed higher values (p˂.05) in both the 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 in C (p˂.05) and a significant decrease in T and T:C before the games lost (M2 and M5). However, there was no linear relation between the variation of both hormones during the matches and the individual performance of players. 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酮的浓度

本研究旨在评估唾液皮质醇（C）、睾酮（T）浓度、比值T:C与顶级女子社会运动员在正式比赛中的个人表现之间的关系。来自国家足球队的18名女运动员（年龄23.06±4.33岁）参与了这项研究。对四场正式比赛进行了分析，计算了每位球员的上场时间以及个人效能指数。根据球员的个人表现，使用K-means将他们分为两组（第1组-较差的个人表现；第2组-良好的个人表现），并比较他们的激素变量。与集群1的参与者相比，集群2的参与者在积极行动和个人有效性方面通常表现出更高的值（p。05）。在四场评估赛中，两组选手的C、T和T:C值相同。第2组运动员在比赛失利前（M2和M5）C显著增加（p＜0.05），T和T:C显著降低。然而，比赛期间两种激素的变化与球员的个人表现之间没有线性关系。比赛中的表现显示了球员之间的显著差异，尽管与比赛前后C和T的激素水平没有明显关系。

期刊介绍： Kinesiology – International Journal of Fundamental and Applied Kinesiology (print ISSN 1331- 1441, online ISSN 1848-638X) publishes twice a year scientific papers and other written material from kinesiology (a scientific discipline which investigates art and science of human movement; in the meaning and scope close to the idiom “sport sciences”) and other adjacent human sciences focused on sport and exercise, primarily from anthropology (biological and cultural alike), medicine, sociology, psychology, natural sciences and mathematics applied to sport in its broadest sense, history, and others. Contributions of high scientific interest, including also results of theoretical analyses and their practical application in physical education, sport, physical recreation and kinesitherapy, are accepted for publication. The following sections define the scope of the journal: Sport and sports activities, Physical education, Recreation/leisure, Kinesiological anthropology, Training methods, Biology of sport and exercise, Sports medicine and physiology of sport, Biomechanics, History of sport and Book reviews with news.
