A influência da fadiga mental no comportamento tático, no perfil motor e na cognição de jogadores de futebol de elite da categoria sub 17

Abstract

This research aims to analyze the influence of mental fatigue on tactical behavior of soccer players, as well as to verify if physical and cognitive variables also change after such phenomenon. To this end, an exploratory study was conducted with athletes from a team of under-17 players from an elite team located in the city of Rio de Janeiro. The research results were presented in two scientific articles. The first article presents the main protocols used to evaluate the effects of mental fatigue on athletes' performance through a systematic literature review. As a result of the first article, the use of the Stroop method is more prevalent in studies aimed at identifying mental fatigue in athletes. The second article corresponds to an exploratory study in which tests of tactical behavior, physical and cognitive performance selected for data collection were applied: Tactical behavior - FUT-SAT; Physical Performance - YoYo Recovery 2; Cognitive Performance - Design Fluency Test. For ease of application and reproducibility we chose the Stroop Test. We used as mental fatigue protocol for 35 min (30 x 60s of stimulus with 10s interval between tests). We use parametric scales to help identify Mental Fatigue and a possible mood change in participants. On the days we applied the tests after the Mental Fatigue protocol, we used the VAS before the Mental Fatigue protocol and at the end we repeated the VAS. The results of the second article indicate that mental fatigue reduces the performance of soccer players. It is concluded that research on the effects of mental fatigue on athlete performance is still incipient and further research is needed to validate the results of this study, as well as contribute to the construction of protocols for reducing mental fatigue among athletes
