- Abstract
The purpose of this study was to evaluate the effects of modified arm swing exercise (MASE) training on oxidative stress, dynamic lung volumes, and heart rate variability (HRV) in patients with chronic obstructive pulmonary disease (COPD). Fifty-six stable COPD patients were each randomly allocated to either the Training Group (TG) (n = 28) or the Control Group (CG) (n = 28). Participants in the TG performed MASE for 30 min·d-1, 6 d·wk-1 for 12 wks; whereas, the subjects in the CG had no exercise intervention. Outcome variables of oxidative stress, dynamic lung volumes, and HRV were assessed before and after the study period. None of the parameters differed significantly between the two groups at baseline and there wasno statistical change in the CG. After undergoing training, the TG showed significant improvement in superoxide dismutase, malondialdehyde, square root of the mean squared differences of successive normal-to-normal intervals, and high frequency (HF) (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 HF. However, forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), and FEV1/FVC ratio did not change significantly after the intervention nor did they differ significantly between the two groups. These results demonstrate that the MASE training improves oxidative stress and HRV in patients with COPD.
