- A influência da condição física inicial dos jogadores de futsal na ocorrência de lesõesPublication . Rebelo, Miguel; Marques, Catarina; Crisóstomo, Rute; Batista, Marco; Paulo, Rui; Rocha, João; Serrano, João; Batista, Marco; Instituto Politécnico de Viana do CasteloApesar de existirem alguns estudos que relacionaram parâmetros de condição física e lesões desportivas, a literatura continua a ser controversa. O objetivo do estudo foi analisar prospectivamente a influência dos parâmetros da condição física inicial no desenvolvimento de lesão nos primeiros três meses da época desportiva em jogadores de futsal. Um total de 68 jogadores (24.26 ± 4.63 anos de idade) foram avaliados antes do início da época desportiva em relação a determinados parâmetros de condição física, como a composição corporal (bioimpedância), a potência dos membros inferiores (countermovement jump, CMJ) e a força muscular (dinamómetro isocinético). Os jogadores lesionados apresentaram um desempenho inicial significativamente pior no CMJ em comparação com os jogadores não lesionados (p < 0.001). Não se registaram diferenças significativas entre os grupos na composição corporal e na força muscular. Valores mais baixos de potência foram associados a um maior risco de lesão nos primeiros meses da época desportiva (OR = 0.92; IC 95% = 0.88 – 0.99). A potência muscular foi um preditor independente de lesões nos primeiros meses da época desportiva em jogadores de futsal, indicando que a melhoria da condição física em geral, nomeadamente, da potência muscular dos jogadores pode ajudar a reduzir o número de lesões.
- The Tempo Giusto: A call for recalibrating time in human movement researchPublication . Ramalho, André; Duarte-Mendes, Pedro; Paulo, Rui; Petrica, João; Routledge Taylor & Francis GroupHuman movement science now runs on accelerating metrics, short grant cycles, and compressed editorial timelines. Speed can deliver rapid outputs but often erodes validity, reproducibility, and conceptual innovation. We advance time-attuned science – tempo giusto – as a design-and-governance concept that calibrates the pace of inquiry to the intrinsic timescales of human movement. Rather than universal deceleration, it prescribes fast evidence when mechanisms and decision horizons warrant it, and sustained observation with planned replication when effects unfold slowly. Delivering this alignment requires systems that reward durability, openness, and societal relevance over volume or venue prestige. A commitment to temporal justice ensures that access to the time required for valid inquiry is widely shared. Where time, method, and purpose converge, findings become cumulative, credible, and enduring.
- Assessment of internal load and external load in senior football players: Differences between competitive levelsPublication . Tereso, Diogo; Gamonales, José M.; Hernández-Beltrán, Víctor; Paulo, RuiBackground: Football is an intermittent sport characterized by high physical and physiological demands, which may be influenced by the competitive level. Understanding differences in match load is fundamental for optimizing training planning, fatigue management, and athlete performance and injury prevention. This study aimed to evaluate and compare external and internal load in senior football players in Portugal across five distinct competitive levels. Methods: Wimu ProTM (Hudl, Lincoln, NE, USA) and Garmin Heart Rate bands (Garmin International Inc., Olathe, KS, USA) were used to quantify and evaluate the external and internal load of the players. A total of 96 athletes were assessed, with ages ranging from 19 to 36 years (mean: 24.28 ± 4.72), who were divided into five competition levels (1st Division (n = 19), 2nd Division (n = 21), 3rd Division (n = 14), 4th Division (n = 20), and Regional Division (n = 22). Results: Significant differences were observed between competitive levels across several external load variables (p > 0.001). The 3rd Division and 4th Division showed higher values in variables associated with reactive and high-intensity actions (p < 0.001; effect size: 0.287), whereas the 2nd Division exhibited a more controlled load profile. Regarding internal load, significant differences were only observed in average heart rate during the second half (p = 0.043; effect size: 0.085), indicating distinct capacities to maintain physiological intensity under fatigue. Conclusions: It can be concluded that competitive level influences load profiles in football, although the differences do not follow a linear pattern. External and internal loads demonstrate greater discriminatory capacity between competitive levels than internal load.
