About

Investigate the effects of exercise training on the cardiopulmonary function and exercise capacity in COPD patients.

Full description

The systemic effects of Chronic Obstructive Pulmonary Disease (COPD) can precipitate a series of complications, including cardiovascular disorders, muscle atrophy, and osteoporosis. These comorbid conditions often result in decreased physical activity and suboptimal physical fitness, compelling patients to lead a sedentary lifestyle to mitigate exercise-induced dyspnea. Addressing the limitations in exercise tolerance remains a critical therapeutic goal in the treatment of COPD. According to research, exercise intolerance is caused by both poor pulmonary function and associated skeletal muscle dysfunction. Blood flow restriction training, a new rehabilitation technique, has shown promise in improving muscular strength at lower exercise intensities and in shorter timeframes, presenting a fresh approach to COPD rehabilitation.

The research aims to investigate the impact of incorporating blood flow restriction training into a holistic aerobic exercise program on exercise capacity and quality of life among patients with COPD. The findings are intended to clarify the potential of this innovative training technique as a supplementary therapeutic strategy in the management of COPD.
