About

Chronic Obstructive Pulmonary Disease (COPD) is a progressive condition marked by airflow limitation and chronic inflammation, leading to reduced exercise capacity, peripheral muscle dysfunction, and dyspnea. High-Intensity Interval Training (HIIT) may offer a promising alternative for patients with low exercise tolerance; however, evidence on its effectiveness remains limited.

This study aims to compare the effects of HIIT and Moderate-Intensity Continuous Training (MICT) on muscle oxygenation, pulmonary function, exercise capacity, and peripheral muscle strength in individuals with COPD. Participants will undergo an 8-week exercise program, twice weekly. HIIT will consist of 1-minute intervals at 90% and 30-40% of peak workload, while MICT will involve continuous cycling at 65% of peak workload. Outcomes will be assessed at baseline, week 4, and week 8. Data will be analyzed using SPSS. This study seeks to determine the more effective training modality to optimize COPD rehabilitation.
