- Abstract
The purpose of this study was to compare quadriceps muscle strength (maximal voluntary contraction, MVC), endurance (TLIM), and dynamic work capacity (WLIM) in 89 patients (57 men and 32 women) with chronic obstructive pulmonary disease (COPD) to 31 healthy controls (20 men and 11 women). Compared with the healthy subjects, COPD patients demonstrated statistically significant (P < 0.05) lower values for MVC, TLIM and WLIM. The MVC was 2030% lower, whereas TLIM and WLIM were 7080% lower in the patients. Stepwise multiple regression analysis revealed that pulmonary function variables contributed only partially to the explanation of variance in MVC, TLIM, and WLIM. Our results indicate that in patients with COPD, quadriceps muscle endurance and dynamic work capacity are impaired to a greater extent than is quadriceps muscle strength. For rehabilitation purposes, the findings may lead to more specific exercise programs, further enhancing rehabilitation outcomes in terms of functional abilities and social participation.
