RESUMO:

Introduction: Pre-competitive anxiety and the physiological responses presented by athletes during competitive matches has become a focus of research in the field of sports psychology. Although futsal is a very popular sport, few studies have looked at the anxiety state of athletes before a competition, especially in the youth team. Objective: To analyze the somatic and cognitive anxiety of school athletes belonging to the U-18 futsal category and their autonomic and hormonal responses. METHODS: Ten athletes (16.9 ± 0.7 years, 71.0 ± 5.1 kg, 174.9 ± 4.3 cm) were monitored during one week of training (WT) (2 weekly sessions lasting 90 minutes) and during 3 matches of a state level competition (2 qualifying matches and 1 eliminatory match, all lasting 40 minutes). Approximately 60 minutes before each match, the CSAI-21 questionnaire was completed to verify the pre-competitive anxiety state. Saliva sample were colleted to analyze cortisol levels and evaluating heart rate variability (HRV) in the time domain (LnRMSSD). Internal match load (IML) was determined using the session-RPE. The one-way test of repeated measures for the analysis of the domains of pre-competitive anxiety was used, the Friedman test was used for the analysis of the variables cortisol and HRV, and for the session-RPE analysis the equations generalized estimates (GHG), followed by Bonferroni post-hoc. Results: The session-RPE presented differences between the matches and training week (W₍₃₎ = 16,392, p = 0.001), showing reduction during the first match in relation to WT (5.2 ± 0.4 vs. 3.4 ± 0.7) and an increase in comparison between the first and third matches (3.4 ± 0.7 vs. 7.0 ± 1.3). The levels of cognitive anxiety were not statistically significant between the matches [F (1.644; 14.799) = 4.6, p = 0.73, partial eta ŋ² = 0.28], as well as, no significant levels of anxiety were found (F (2.09; 18.85) = 26.07 p = 0.057 partial eta ŋ² = 0.27] and in self-confidence [F (2.07; 18.85) = 15.875 p = 0.152 partial eta ŋ² = 0.18]. The values of LnRMSSD did not present changes between the matches [χ² (3) = 3,360, p = 0,339], as well as the values of cortisol χ² (3) = 4,320 p = 0,229. Conclusion: this competition model did not cause changes in the anxiety state of the participants, not altering the values of the salivary cortisol and the autonomic activity.
