- Abstract
The hormones testosterone and cortisol have an antagonistic action in the body, and the testosterone/cortisol ratio is used to assess the anabolic/catabolic state of football players. We sought to evaluate the variations in the concentrations of these hormones throughout a high-density competitive season. The study included 23 male athletes from a team of the first division of national football in the context of the World Cup, divided into holders and reserves. Seven blood samples were collected during the match schedule (M0 to M6). For the statistical analysis, two-way ANOVA for repeated measurements was used, followed by Tukey's post hoc. A correlation matrix between the variables was obtained using Pearson's coefficient. The significance level was p<0.05. The holders had higher concentrations of testosterone compared to the reserves in M0 and M4. Cortisol concentrations were lower in reserves compared to holders in M2, M3, M5 and M6. In holders and reserves, the T/C ratio showed a significant correlation with the density of games (r = -0.94 and r = -0.80, respectively), with the differences in the averages of the T/C ratio being significant between holders and reserves in M2, M3, M5 and M6. The study confirms the relationship between the magnitude of hormonal variation with the greater physiological demand of a season with high volume of games. It is concluded that the evaluation of the responses of the endocrine system can help in the planning of training sessions.
