Impaired Skeletal Muscle Endurance Related to Physical Inactivity and Altered Lung Function in COPD Patients

exercise test. Results: Theresults showedthatTlimandPA score were significantly decreased inCOPD patients (p<0.05). Significant positive correlations were found intheCOPDgroup between Tlim andthePAscore(r=0.60; p<0.05), FEVX(r=0.52; p<0.05), andPa02(r=0.63; p<0.05). Thesame results were found between thePAscoreandVo2si(r=0.57; p<0.05) andFEVX(r=0.63; p<0.05). Conclusion: Thesefindings indicate impaired skeletal muscle endurance inCOPD patients related toaltered lung function andassociated physical inactivity. (CHEST 1998; 113:900-05)
