Resumo(s)
Com o avançar da idade observa-se a redução natural da capacidade funcional. Dentro das capacidades funcionais, a força/velocidade muscular dos membros inferiores (MMII) Ă© fundamental para realizar satisfatoriamente as atividades da vida diĂĄria (AVDs). Fatores como a idade e os nĂveis de flexibilidade podem afetar o desempenho de MMII em idosos. Objetivo: Analisar a influĂȘncia da idade cronolĂłgica e da flexibilidade de MMII na velocidade de membros inferiores de idosos fisicamente ativos. MĂ©todos: Este foi um estudo observacional, transversal e prospetivo, com 41 idosos (34 idosas e 7 idosos), mĂ©dia de de 69 ± 12,7 anos, que foram submetidos aos testes de seat and reach: flexibilidade de MMII, e sit to stand five time (STS 5x): para avaliar a velocidade dos MMII. Os dados foram apresentados em mĂ©dia ± desvio padrĂŁo e valores percentuais. Foi realizada uma anĂĄlise de regressĂŁo mĂșlplica hierĂĄquica entre a idade cronolĂłgica e a flexibilidade de MMII para a variĂĄvel de resposta velocidade de MMII. O tamanho do efeito foi calculado por meio do coeficiente de determinação (R2). Foi adotado um nĂvel de significĂąncia de p < 0,05. Resultados: NĂŁo foi encontrada influĂȘncia da idade cronolĂłgica e do nĂvel de flexibilidade de MMII com a velocidade de MMII dos idosos fisicamente ativos, F = 1,186, gl = 39, p = 0,31, R2 = 0,008. ConclusĂŁo: Conclui-se que a idade cronolĂłgica e a flexibilidade de MMII nĂŁo determinaram a velocidade de MMII de idosos fisicamente ativos.
With the advancing of age, there is a natural reduction in functional capacity. Among functional capabilities, lower limb muscle strength/velocity (LL) is essential to satisfactorily perform activities of daily living (ADLs). Factors such as age and flexibility levels can affect the lower limb performance of older people. Objective: To analyze the influence of chronological age and lower limb flexibility on the LL velocity in physically active older people. Methods: This was an observational, transversal, and prospective study, with 41 older people (34 women and 7 men), a mean age of 69 ± 12.7 years, who underwent seat and reach tests: LL flexibility, and sit-to-stand five-time (STS 5x): to assess the LL velocity. Data were presented as mean ± standard deviation and percentage values. A hierarchical multiple regression analysis was performed between chronological age and LL flexibility for the response variable LL velocity. The effect size (ES) was calculated through the coefficient of determination (R2). A significance level of p < 0.05 was adopted. Results: There was no influence of the chronological age and the LL flexibility level with the LL velocity of the physically active older people, F = 1.186, df = 39, p = 0.31, R2 = 0.008. Conclusion: It is concluded that chronological age and LL flexibility did not determine the LL velocity of physically active older people.
