The present study aims to analyze the effects of consecutive futsal games on neuromuscular performance and rating of perceived exertion in athletes. Fourteen male futsal players (16.5 ± 0.51 years, 67.5 ± 11.1 kg; 1.73 ± 0.08 cm; 22.5 ± 2.3kg/m²) from a youth futsal team took part at the study. Our research monitored the team throughout the 4-day qualifying phase of the Campeonato Paranaense de Futsal (the Youth Futsal Championship of the State of Paraná, Brazil). The athletes underwent the following tests immediately after each futsal match: vertical jump test (Squat Jump (SJ)), Countermovement Jump test (CMJ), and a rating of perceived exertion (s-RPE) session. Magnitude based inference analysis reported CMJ values likely lower after the 2nd match when compared with the results obtained after the 1st and 4th matches: (ES= -0.46 low) and (ES= -0.53 moderate), respectively. Furthermore, SJ values reported after the 2nd match are likely lower if compared with the outcomes obtained after the 1st match (ES= -0.56 moderate) and possibly lower when compared with the 3rd matches (ES= -0.45 low). PSE results were significantly different comparing the 1st and 2nd matches (p=0.04); the 1st and 3rd matches (p=0.01); and the 3rd and 4th matches (p=0.01). Moreover, the outcomes research obtained after the 1st match are very likely to be lower when compared with the results from the 2nd (ES= -0.97 high) and 3rd matches (ES= high); and almost certain lower when compared with the 2nd and 3rd matches (ES= -0.45 low). Test results research obtained after the 4th match are very likely to be lower than the ones from the 2nd (EF=-0.83 high) and 3rd matches (ES= 1.01 high). Thus, by investigating the youth futsal tournament, the study could observe under-17 athletes delivered a decreased performance in vertical jump tests throughout the 4-consecutive-day championship, which can be associated with an increased rating of perceived exertion.Keywords: team sports, physical performance, fatigue, muscle damage.
