Análise do curso temporal da recuperação da potência muscular em jovens futebolistas durante um microciclo

Abstract

Due to the significant importance of neuromuscular capabilities in football, this study aims to analyze the influence of high-intensity actions on muscle power recovery. The hypothesis is that sprints exceeding 20 km/h, along with acceleration and deceleration actions, can impact muscle power recovery. A total of 15 football players participated in the research, with a mean age of 19.27 (±0.88) years, height of 1.81 (±0.07) m, and mass of 74.93 (±7.03) kg. Daily psychological recovery data were collected using a Recovery State Questionnaire (PSR). Participants performed three vertical jump tests (SVCM) to assess maximum jump height. Displacement variables were collected via GPS during and after training sessions, alongside psychological load assessments using the Rating of Perceived Exertion (RPE) questionnaire. The results indicate that muscle power did not show significant variation through inferential statistics; however, analysis using the Minimum Viable Product (MMVP) revealed differences at 120 hours compared to the best performance day. In terms of displacement variables during friendly matches, greater distances were recorded in the microcycle, with significant differences across all training sessions, particularly in the speed ranges of 15.1 to 20 km/h and 20.1 to 25 km/h. Additionally, it was observed that muscle power did not improve in the 96-hour test, despite session 4 recording the least distance covered in the microcycle. Notably, in session 4, the "beginners" group covered ten times more distance above 25 km/h than the "substitutes" group. Therefore, it is concluded that high-intensity actions influence muscle power recovery, and MMVP statistics can be utilized within these groups to assess potential changes in muscle power parameters.
