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

Abstract

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. Forty-five miners 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. 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. It is suggested that miners suffering from COPD, consider HIIT as part of their treatment plan.
