The objective of this study was to explore the short- and long-term effects of lower-limb endurance training on chronic obstructive pulmonary disease outpatients. The study found that the training group showed significant improvement in the chronic obstructive pulmonary disease assessment test scores and reduced acute exacerbations after completing the training and sustaining for a year. Lower-limb endurance training can improve perceived dyspnea in daily activity and health status, and alleviate the impact of the disease on acute exacerbations.
Objective To explore the short- and long-term effects of lower-limb endurance training on chronic obstructive pulmonary disease outpatients. Design Prospective quasi-experimental study. Setting 1383-bed teaching hospital in Taiwan. Participants Overall, 69 outpatients diagnosed with chronic obstructive pulmonary disease were enrolled. A total of 60 patients completed the study. Intervention Training group: Lower-limb endurance training; control group: Education only. Main measures The modified medical research council score, chronic obstructive pulmonary disease assessment test score, pulmonary function test, and number of acute exacerbation within a year. Results The training group showed significant improvement in the chronic obstructive pulmonary disease assessment test total score, modified medical research council score (both P < 0.001) at third month sustaining to 12th month (P < 0.001) and presented less events of acute exacerbation (P = 0.011) at 12th month. The chronic obstructive pulmonary disease assessment test decreased by 8 points sustaining to 12th month. The training group presented significant post-training functional capacity improvements in 6-min walking distance, lowest oxygen saturation during 6-min walking test, peak workload, maximum inspiratory/ expiratory pressures, and calf circumference. Conclusions The lower-limb endurance training improved perceived dyspnea in daily activity and health status after completion of training and sustaining for a year. The lower-limb endurance training alleviated disease impacted on reduced acute exacerbations.
