Resumo: Background: Sprint running is a key factor of performance for team sports as football and futsal. Force-power-velocity relationships and mechanical effectiveness have been recently used to analyse force-velocity (F-V) profiles. The aim of this study was two-fold: (1) to quantify the sprint mechanical F-V profiles in Portuguese football and futsal players; (2) to analyse differences among sexes, competitive levels and sports on sprint mechanical variables in Portuguese football and futsal players. Methods: Four football players (2 mens) and four futsal players (2 mens), aged 26 ± 4.24 years, performed a 3 maximal sprints of 30 m from a standing position with 4 min of rest between successive sprints. Video data was collected with a Go Pro Hero (Full HD 1080p, 30 fps). Force-velocity profile was obtained with time motion data: F0 (N/kg), V0 (m/s), Pmax (W/kg), Sfv, RFmax (%), DRF (%), Vopt (m/s) and max speed (m/s). Results: Men’s players showed a higher V0 (t = -7.12;p<0.001,d=5.04),Vopt (t=-2.90;p≤ 0.05,d=2.05)andmaxspeed(t=-5.09;p≤ 0.05, d = 3.60) than women players. No differences with statistical significance were observed among competitive levels and sports. Conclusion: These results showed that the sprint mechanical F-V profiles is able to distinguish between men and women football and futsal players. No differences among competitive levels could be due to the low competitive level of the sample. Future research should include different competitive level such as elite, sub-elite and recreational.

As relações força-potência-velocidade e eficácia mecânica têm sido recentemente utilizadas para analisar perfis de força-velocidade (F-V). O objetivo deste estudo era duplo: (1) quantificar os perfis biomecânicos F-V do sprint em jogadores de futebol e futsal portugueses; (2) analisar diferenças entre sexos, níveis competitivos e desportos nas variáveis em estudo. Métodos – 4 jogadores de futebol (2 homens) e 4 jogadores de futsal (2 homens), com 26 ± 4,24 anos, realizaram 3 sprints máximos de 30 m a partir de uma posição de pé com 4 min de descanso entre sprints sucessivos. Foram recolhidos dados de vídeo com um Go Pro Hero (Full HD 1080p, 30 fps). O perfil de força- velocidade foi obtido com: F0 (N/kg), V0 (m/s), Pmax (W/kg), Sfv, RFmax (%), DRF (%), Vopt (m/s) e velocidade máxima (m/s). Results – Os jogadores masculinos mostraram umV0 (t=-7,12;p<0,001,d=5,04),Vopt (t=- 2,90; p ≤ 0,05, d = 2,05) e velocidade máxima (t =-5,09;p≤0,05,d=3,60)maisaltadoque nas jogadoras femininas. Não foram observadas diferenças com significado estatístico entre os níveis competitivos e o desporto. Conclusão – Estes resultados mostraram que os perfis mecânicos de sprint (F-V) são capazes de diferenciar entre jogadores masculinos e femininos de futebol e jogadores de futsal. Nenhuma diferença entre os níveis competitivos pode dever-se ao baixo nível competitivo da amostra. A investigação futura deve incluir diferentes níveis competitivos, tais como elite, subelite e recreativo.ISCE DouroBiblioteca Digital do IPBTeixeira, José EduardoTouças, PauloBraga, Tiago JoséMonteiro, A.M.Forte, PedroBarbosa, Tiago M.2023-05-24T10:18:55Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10198/28359engTeixeira, José Eduardo; Touças, Paulo; Braga, Tiago; Monteiro, A.M.; Forte, Pedro; Barbosa, Tiago M.
