Previous issue date: 2017-06-01 / Objetivo: Comparar as respostas neuromusculares e bioqu?micas do dano e fadiga muscular do quadr?ceps femoral entre indiv?duos com DPOC e saud?veis. M?todos: Tratou-se de um estudo observacional, transversal e comparativo. A amostra foi composta por 18 indiv?duos alocados em dois grupos distintos: Grupo DPOC (GD) e Grupo Saud?veis (GS) que foram avaliados atrav?s da fun??o pulmonar; do desempenho neuromuscular do quadr?ceps; os marcadores bioqu?micos do dano e fadiga muscular; fatigabilidade e dor muscular. Os dados foram analisados com o software Statistical Package for the Social Sciences (SPSS) vers?o 20.0 com n?vel de signific?ncia de 5%. Resultados: Observou-se diferen?a estatisticamente significante na pot?ncia entre o GD e GS (99,0 vs 145,1; p=0,02) e uma tend?ncia ? diferen?a no trabalho total, respectivamente (1.035,5 vs 1.671,5; p=0,06) entre os grupos. Na an?lise do marcador bioqu?mico, o LDH, para fadiga muscular foi observado diferen?a significativa entre os grupos imediatamente ap?s o teste isocin?tico no quadr?ceps (402,3 vs 289,4; p=0,03). Conclus?es: As respostas neuromusculares e bioqu?micas do dano e fadiga muscular do quadr?ceps femoral no DPOC apresentam-se diminu?da na popula??o estudada. / Objective: To compare neuromuscular and biochemical responses of femoral quadriceps muscle damage and fatigue among COPD and healthy individuals. Methods: This was an observational, cross-sectional and comparative study. The sample consisted of 18 individuals allocated to two distinct groups: COPD Group (GD) and Healthy Group (GS) who were evaluated through lung function; of the neuromuscular performance of the quadriceps; The biochemical markers of muscle damage and fatigue; fatigue and muscle pain. Data were analyzed using Statistical Package for Social Sciences (SPSS) version 20.0 with a significance level of 5%. Results: There was a statistically significant difference in the power between GD and GS (99.0 vs 145.1; p = 0.02) and a tendency to the difference in total work, respectively (1,035.5 vs 1,671.5; p = 0.06) between groups. In the analysis of the biochemical marker, LDH, for muscle fatigue was observed a significant difference between the groups immediately after the isokinetic test in the quadriceps (402.3 vs 289.4; p = 0.03). Conclusions: The neuromuscular and biochemical responses of femoral quadriceps muscle damage and fatigue in COPD are diminished in the study population.
