Resumo
Finalidade: O alongamento muscular é aplicado com a finalidade de aumentar a amplitude de movimento. Para tanto, diversas técnicas são utilizadas, dentre elas: facilitação neuromuscular proprioceptiva (FNP) e alongamento dinâmico, mas ainda não se sabe qual delas é mais eficaz. O objetivo desta investigação foi estimar a eficácia da técnica segurar-relaxar em comparação com o alongamento dinâmico na flexibilidade dos isquiotibiais em adultos jovens saudáveis.
Metodologia: Ensaio clínico randomizado, cego, controlado por dois braços. Um total de 32 voluntários adultos jovens com idades entre 18 e 30 anos participaram do estudo e foram randomizados para dois grupos de intervenção FNP (n = 16), dinâmico (n = 16). A flexibilidade da articulação do joelho foi avaliada por meio do ângulo poplíteo por goniometria.
Resultados: os resultados das médias de idade, peso, altura e índice de massa corporal são equivalentes, o que indica grupos comparáveis entre si. Não foram encontradas diferenças entre os grupos de alongamento nas médias ajustadas - 2,09 (IC 95 % -7,05 a 2,87).
Conclusões: tanto a técnica dinâmica quanto o PNF aumentaram a amplitude de movimento do joelho, ambas as técnicas de alongamento apresentaram diferenças com a linha de base. Não foram encontradas diferenças entre os grupos de alongamento.
