The purpose of this study was to evaluate the effects of modified arm swing exercise (MASE) training on pulmonary function, exercise capacity, and quality of life (QOL) in patients with chronic obstructive pulmonary disease (COPD). Fifty-six stable COPD patients were randomly assigned to either the Training Group (TG) (n = 28) or the Control Group (CG) (n = 28). Subjects in the TG (MASE training for 30 min·d-1, 6 d·wk-1) and the CG (no exercise intervention) were followed for 12 weeks. Outcome variables of lung function, exercise capacity, and QOL were assessed before and after the study period. After 12 weeks, 50 participants completed the study and were analyzed. The TG showed significant improvement in maximal inspiratory pressure, maximal expiratory pressure, peak expiratory flow (PEF), six-minute walk distance (6MWD), and QOL (P<0.05). In addition, all variables that had changed in the TG also differed significantly from those in the CG (P<0.05), except for PEF. However, other variables of pulmonary function did not change significantly after the intervention nor did they differ significantly between the two groups. These results show that the MASE training increase respiratory muscle strength, exercise capacity, and QOL in patients with COPD. [ABSTRACT FROM AUTHOR] |
