Effects of High and moderate-Intensity Interval Training on pulmonary and performance parameters in miners suffering from Chronic Obstructive Pulmonary Diseases

چکیده مقاله

Objective: To characterize the effect of 12 weeks of high and moderate-intensity interval training on pulmonary and functional parameters in miners with chronic obstructive pulmonary disease working in the polluted environment. Methods: 45 miner with COPD (average degree: 60 > FEV1 < 70), were randomly divided into HIIT, (With 100–125% ISWT); MIIT, (with 60–85% ISWT), and control. The study period was 12 weeks (3 sessions per week). At the beginning and end of the study, pulmonary and functional indices was evaluated. Results: Based on results, HIIT and MIIT significantly increased FVC, FEV1, and mean traveled distance in ISWT compared with control. Comparison of training intensities showed that HIIT led to a significant change in FVC, FEV1 and ISWT record compared to MIIT. Conclusion: It is suggested that miners suffering from COPD, consider HIIT as part of their treatment plan.
