- How weekly monitoring variables influence players’ and teams’ match performance in elite futsal playersPublication . Ribeiro, João Nuno; Monteiro, Diogo; Sampaio, Jaime; Couceiro, Micael; Travassos, BrunoThis study aimed to investigate how weekly training load constrains the performance of players and teams in official futsal competitions. Data from a professional male team were collected during two seasons (46 weeks). The applied monitoring system analysed the training load (as measured by session perceived exertion, sRPE), the total recovery status (TQR), the well-being score (WBs) and the variability of neuromuscular performance during each week (CMJ-cv). In addition, the performance was assessed for all the matches. A path analysis model was performed to test the associations across variables. Results from the path analysis model revealed that it explains 31% of the teams’ performance. In general, the results show that previous team performance has no significant effects on the training week. A significant negative relationship was found between CMJ-cv and match performance (β = -.34; CI95% -.359 to -.070), as well as a significant negative relationship between players’ match performance and the team’s match performance (β = -.55; CI95% -.292 to .740). Regarding indirect effects, only a negative association between CMJ-cv and team match performance via players’ match performance (β = -.19; CI95% -.342 to -.049) was identified. The small variation of the weekly CMJ (CMJ-cv) seems to be a key variable to monitor and explain both player and team performance. Based on this model, and only looking at the physical variables, it was possible to explain 31% of the team’s performance. Longitudinal and multi-team studies should be conducted to integrate other technical, tactical and psychological variables that allow the level of understanding of players’ and teams’ performance to be improved.
- Relating external load variables with individual tactical actions with reference to playing position: an integrated analysis for elite futsalPublication . Ribeiro, João Nuno; Yousefian, Farzad; Monteiro, Diogo; Illa, Jordi; Couceiro, Micael; Sampaio, Jaime; Travassos, BrunoThe purpose of this study was to contextualise players’ high-intensity activities (HIA) with individual tactical actions during match play with reference to playing positions. Tracking data was obtained using local positioning system devices from 19 male elite futsal players (28.8 ± 2.4 years). The HIA measures included high-intensity acceleration (ACC; ≥3 m · s−2), deceleration (DEC; ≤−3 m · s−2), and high-speed running (HSR; ≥18 km · h−1). Tracking data and match footage were synchronised using the SPRO™ to code players’ physical performance and technical-tactical actions. A small statistically significant association was observed between HIA and players’ actions with or without the ball (χ2 = 183.27 (2, N = 4234), p<.001; Cramer’s V = 0.21). When players have the ball, the number of DEC efforts tends to increase with a corresponding decrease in ACC and HSR. When the players do not have the ball, ACC and HSR running tend to increase with a corresponding decrease in DEC. A comparison between HIA revealed that futsal performance requires greater mechanical efforts (ACC + DEC) than kinematic efforts (HSR). This underscores the importance of mechanical efforts within short space for futsal performance. Moreover, the diverse tactical actions associated with different player positions contribute to distinct activity profiles and physical requirements.
- Short-interval consecutive goals and performance outcomes in elite women’s futsalPublication . Carvalho, Rute; Monteiro, Diogo; Costa, Júlio A.; Sampaio, Jaime; Travassos, BrunoThe goal of this study was to examine the impact of short-interval consecutive goals (SICGs), defined as ≥ 2 goals scored within three minutes, on team performance in elite women’s futsal. Goal timings from 132 matches of the 2024–2025 Portuguese Women’s Senior Futsal League were extracted from official reports. Goals inside and outside SICGs, match result, and league ranking were recorded. Path analysis using Structural Equation Modelling (SEM) tested model fit and direct and indirect paths among all variables. SICGs occurred in most matches and accounted for over half of all goals, clustering in the opening and closing periods of each half. Scoring SICGs was positively associated with points (β = .30, p = .003), whereas conceding SICGs was negatively associated (β = −.24, p = .003). Combined, these effects explained 50% of the variance in points earned and 40% in final league ranking. SICGs appear to be critical tactical and psychological junctures in elite women’s futsal, with implications for match outcomes and season-long classification. Coaches may benefit from anticipating these high-leverage periods to enhance match management and prepare players for moments of advantage or disadvantage. Future research should clarify the role of SICGs in psychological momentum.
- Variation in Physical Performance of Futsal Players During Congested FixturesPublication . Ribeiro, João Nuno; Monteiro, Diogo; Gonçalves, Bruno; Brito, João; Sampaio, Jaime; Travassos, BrunoPurpose: To investigate the match-to-match variation of physical performance during official congested fixtures in elite futsal players. Methods: Physical performance was measured by external and internal load metrics in 12 elite male futsal players. Two periods with 3 matches within 4 days were analyzed. The variation in physical performance of the players during matches was analyzed using the latent growth curve modeling that estimated interindividual and intraindividual growth paths. Results: Playing time had a significant effect on physical performance growth with significant paths of interindividual and intraindividual variability. Players who competed for more time revealed lower initial levels (ie, first match) of total distance covered (β = −0.62), high-speed running (β = −0.18), accelerations (β = −0.31), decelerations (β = −0.44), and session rate of perceived exertion (β = 0.81) than players who competed for less time (P < .05). In addition, players who competed for more time revealed higher increases in total distance covered (β = 0.47), high-speed running (β = 0.16), and session rate of perceived exertion (β = 0.66) and lower increases in accelerations (β = −0.21) and decelerations (β = −0.58) than players who competed for less time from the first to the third match (P < .05). Conclusions: Congested fixtures did not affect physical performance in elite futsal players. Playing time showed to be a key performance factor. There was a considerable heterogeneity in the responsiveness to physical performance over congested fixtures, suggesting an analysis of individual variability to evaluate real changes in match performance, training intensity, and workload.
