RESUMO:

The monitoring of biochemical and perceptual components elucidating the psychophysiological behavior of young athletes exposed to a competitive load is of fundamental importance for adequacy of physiological overloads during sports development period. Objective: The objective of this study was to analyze the psychophysiological stress resulting from sports competitions in under 17 category of teenagers also investigate the association between competitive internal load (session RPE and salivary cortisol) with the period of time played. Methodology: The research was characterized as a descriptive, non-experimental, longitudinal study with a quantitative approach. A total of 20 (16.8 ± 0.5years; 172.9 ± 7.7cm; 65.0 ± 7.9kg; 8.3 ± 1.8% body fat; 53.1 ± 2,0ml.kg.min-1) soccer players under 17 category, held two successive matches (M1 e M2) in similar times, with an interval of 24 hours between them. To determine the competitive internal load used the salivary cortisol (pre and post matches), and the session RPE. The time of each athlete field was timed to determine the internal load the session RPE. 14 athletes completed at least 15 minutes of play and were included in the analysis. Paired t-test was used to compare the salivary cortisol levels before and after in both matches, besides session RPE, the time in the field and score the CR-10. To compare the variation of cortisol concentration was used the Wilcoxon test. As a follow-up, we divide the group according to the median of the players in the field of time (above n = 8; n = 6 below). To compare the concentration of pre and post matches cortisol was used the Wilcoxon test. To compare the groups of variables RPE score, session RPE and time in the field was the Mann Whitney test was used. Results: It was observed that salivary cortisol concentrations ranged from pre moment for the post when both sets (M1: t (13) = 3.193, p <0.01; M2: t (13) = 5.265, p <0.01). Cortisol value according to the division of the groups varied only in the group that had more time in the field in both games (M1: Z = -2,103, p <0.05; M2: Z = -2,521, p <0.05). No difference was found between the change in cortisol values between matches (Z = -1,601, p = 0.10). There was not difference between matches in the remaining variables (Session PSE: t (13) = 1.249, p = 0.23; PSE score: t (13) = 1.046, p = 0.31; field in time t (13) = 0.868, p = 0.40. Conclusion: In conclusion, sports competitions trigger an increase in salivary cortisol concentrations also appears that this variation may be due to time in the field in young soccer players.
