Abstract(s)
Objetivo: Verificar o efeito do alongamento estático (AE) no senso de posição articular (SPA) do joelho de jogadores de futebol.
Metodologia: Neste estudo randomizado controlado participaram 17 jogadores de futebol do sexo masculino sujeitos a 3 condições: 2 condições experimentais, de AE do quadricípite e isquiotibiais de 30s e 90s, e uma condição de controlo (repouso). A avaliação do SPA do joelho foi realizada antes e imediatamente após cada condição, na posição de sentado e considerando um reposicionamento ativo para uma amplitude de 45º.
Resultados: Nas comparações intergrupos, a condição de AE de 90s apresentou um erro absoluto significativamente superior ao controlo (p=0.003). Nos erros relativos, o AE de 90s registou igualmente erros significativamente superiores ao controlo (p=0.006) e ao AE de 30s (p=0.004).
Conclusão: Os resultados sugerem que o AE do quadricípite e isquiotibiais realizado por 90s parece ter efeitos negativos no SPA do joelho de jogadores de futebol, enquanto que quando realizado por 30s, parece não produzir alterações significativas.
Aim: To verify the effect of static stretching (SS) on the knee joint positions sense (JPS) of soccer players. Methodology: In this randomized controlled trial, 17 male soccer players participated in 3 conditions: 2 experimental conditions, of SS of the quadriceps and hamstrings for 30s and 90s, and a control condition (rest). Knee JPS assessment was performed before and immediately after each condition, in a sitting position and considering an active repositioning to the range of 45°. Results: In the intergroup comparisons, the SS of 90s presented a significantly higher absolute error than the control (p=0.003). In terms of relative errors, the SS of 90s also recorded significantly higher errors than the control (p=0.006) and than the SS of 30s (p=0.004). Conclusion: the results suggest that the SS of the quadriceps and hamstrings performed for 90s seems to have negative effects on the knee JPS of soccer players, while when performed for 30s, it does not seem to produce significant changes.
