MethodsA cross-sectional and observational study of thirty patients referred to a pulmonary rehabilita tion programme at a university hospital. Lung function was evaluated by spirometry, arterial blood gas analysis and nocturnal oximetry. Muscle function was evaluated by quadriceps strength and functional capacity by the 6MWT. ResultsBivariate regression analysis showed that quadriceps strength, was the only variable to correlate significantly with the distance walked in the 6MWT (p=0.002), accounting for 38% of the 6MWT variance. The statistical relationship established for these variables was 1kg of quadriceps strength equalled 5.9 metres walked in the 6MWT. ConclusionsOur results showed the importance of lower limb muscle strength in submaximal exercise testing. We conclude that femoral quadriceps muscle strength is the only one of the variables studied which can predict the distance COPD patients walk in the 6MWT." ] "pt" => array:2 [ "titulo" => "Resumo" "resumen" => "ObjectivoDeterminar que variável entre o volume expirado forçado no primeiro segundo (VEF1), a pressão parcial do oxigénio no sangue arterial (PaO2), a hipoxemia nocturna e a força muscular do quadricípite femoral pode predizer a distância percorrida no teste de caminhada de seis minutos (TC6) em doentes com DPOC. Doentes e métodosUm estudo observacional do tipo transversal, envolvendo trinta doentes encaminhados a um programa de reabilitação pulmonar de um hospital universitário. A função pulmonar foi avaliada por espirometria, gasometria arterial e oximetria nocturna. A função muscular pela força muscular do quadricípite femoral e a avaliação da capacidade funcional pelo TC6. ResultadosA análise de regressão bivariada mostrou que a força do quadricípite femoral foi a única variável que se mostrou estatisticamente significativa (p = 0,002) em predizer a distância, sendo responsável por 38% da variância do TC6. Para essas variáveis a relação estabelecida estatisticamente foi que para cada quilo de força do quadricípite femoral, os doentes caminharam 5,9 metros no TC6. ConclusãoOs resultados indicam a importância da força muscular do MI em testes de esforço submáximo.
