Effects of High and Moderate-Intensity Interval Training on Pulmonary and Performance Parameters in Miners Suffering From Chronic Obstructive Pulmonary Diseases

Abstract

Objective: To characterize the effect of 12 weeks of high and moderateintensity interval training on pulmonary and functional parameters in miners with chronic obstructive pulmonary disease working in the polluted environment. Methods: Forty-five miners with COPD (average degree: 60 > FEV 1 < 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, FEV 1 , and mean traveled distance in ISWT compared with control. Comparison of training intensities showed that HIIT led to a significant change in FVC, FEV 1 , and ISWT record compared to MIIT. Conclusion: It is suggested that miners suffering from COPD, consider HIIT as part of their treatment plan.
