Objetivo: Investigar a influência do alongamento estático (AE) no senso de posição articular (SPA) do tornozelo de jogadores de futebol. Metodologia: Este estudo randomizado controlado incluiu 19 jogadores de futebol. Todos os participantes realizaram as 3 condições do estudo (crossover): 2 condições experimentais, de AE dos gastrocnémios e tibial anterior por 30s e 90s, e 1 condição de controlo (repouso). O SPA foi avaliado antes e imediatamente após as 3 condições para a amplitude de 20º de flexão plantar, e por reposicionamento ativo do membro dominante. Resultados: Não se verificaram diferenças significativas entre a avaliação antes e após em nenhuma das condições, nem foram registadas diferenças significativas entre condições nos erros absolutos ou relativos (p>0.05). Apenas os erros variáveis indicaram uma melhoria significativa na consistência entre reposicionamentos nas condições de controlo (p=0.024) e de AE de 30s (p=0.025), embora sem diferenças entre condições (p>0.05). Conclusão: Os resultados sugerem que o AE dos gastrocnémios e tibial anterior, realizado por 30s ou 90s, não parece influenciar o SPA do tornozelo de jogadores de futebol.
Aim: To investigate the influence of static stretching (SS) on the ankle joint position sense (JPS) of soccer players. Methodology: This randomized controlled trial included 19 soccer players. All participants performed the 3 study conditions (crossover): 2 experimental conditions, of SS of the gastrocnemius and tibialis anterior for 30s and 90s, and 1 control condition (rest). JPS was assessed before and immediately after the 3 conditions for the range of 20º of plantar flexion, and by active repositioning of the dominant limb. Results: There were no significant differences between the assessments before and after in any of the conditions, neither were there significant differences between conditions in absolute or relative errors (p>0.05). Only variable errors indicated a significant improvement in consistency between repositionings in the control (p=0.024) and SS of 30s (p=0.025) conditions, although without differences between conditions (p>0.05). Conclusion: The results suggest that the SS of the gastrocnemius and tibialis anterior, performed for 30s or 90s, does not seem to influence the ankle JPS of soccer players.
