Purpose: This study aims to compare the effects of the classical pulmonary rehabilitation (PR) program and blood flow restriction (BFR) applied during low-intensity aerobic exercise within PR on systemic inflammation, hypoxemia, exercise capacity, pulmonary function, respiratory muscle strength, and quality-of-life parameters in individuals with COPD. Methods: This randomized controlled study will include 34 individuals with COPD, allocated into a BFR aerobic group and a control group. Both groups will receive core PR components, including diaphragmatic breathing, pursed-lip breathing, respiratory muscle training, and peripheral muscle strengthening. The BFR group will perform low-intensity aerobic exercise with blood flow restriction, while the control group will perform moderate-intensity aerobic exercise without BFR in accordance with standard PR protocols. All sessions will be supervised by a physiotherapist, twice per week, for eight weeks. Systemic inflammation markers, arterial blood gases, pulmonary function, exercise capacity, quality of life, and symptom scores will be assessed before PR, after the 8th session, and at the end of the program. Data will be analyzed using SPSS 26.0. Expected Contribution: This study aims to provide evidence-based insights into the physiological and clinical effects of low-intensity BFR aerobic exercise within PR and to determine its potential advantages compared with classical PR. Additionally, it seeks to clarify whether low-intensity BFR aerobic exercise may serve as a better-tolerated alternative for COPD patients who experience exercise intolerance during moderate-intensity aerobic training.
