dc.description.abstractThe aim of this study was to investigate the effect of combined high intensity interval training (HIIT) and inspiratory muscle training (IMT) on pulmonary function and exercise capacity in patients COPD. This randomized, controlled trial study involved 100 COPD patients (GOLD stages II and III) aged between 40 and 70 years. Subjects were randomly assigned to one of two groups. The study group (n=50) underwent 8 weeks combined HIIT and IMT. The HIIT protocol involved four intervals, each lasting 4 minutes, beginning at 70% of maximum power and building to a target intensity of at least 85% HRmax. The IMT sessions included 2-3 sets of 30 breaths (totaling 60-90 breaths per session), with a two-minute rest between sets, three days per week starting with 30% of PImax and reaching 60% of PImax. The control group (n=50) performed an 8-week program of therapeutic education and 30-min self-based cycling or walking. Pulmonary function tests, incremental cycle ergometer tests, 6 min walk tests and inspiratory muscle strength were performed, and dyspnea and Halth-Related Quality of Life (HRQoL) were assessed before and after the intervention period. Results indicated that combined HIIT and IMT significantly improved exercise capacity, respiratory muscle strength, dyspnea, and quality of life in patients with COPD (p<0.05). There were no significant changes in pulmonary functions (p>0.05). This study suggests that integrating HIIT with IMT can effectively enhance the overall prognosis of patients with COPD.
