Effects Of Low-Load Blood Flow Restriction Training Of The Upper Extremity In Patients With Chronic Obstructive Pulmonary Disease

Recruiting now · Not applicable · Has a placebo group

Conditions studied: Chronic Obstructive Pulmonary Disease (COPD), Blood Flow Restriction Training (BFRT)

In brief

Chronic Obstructive Pulmonary Disease (COPD) is characterized by persistent airflow limitation, progressive dyspnea, and peripheral muscle dysfunction, significantly impairing functional capacity and quality of life. Although the combined implementation of aerobic and resistance exercises is recommended in pulmonary rehabilitation programs, early-onset ventilatory limitation in individuals with COPD often hinders tolerance to high exercise intensities. This limitation increases the need for alternative exercise approaches targeting peripheral muscle adaptations. Low-load blood flow restriction training (LL-BFRT), which enables improvements in muscle strength with low mechanical loads, has emerged as a potential option for this patient population. However, evidence regarding the effects of LL-BFRT in individuals with COPD-particularly on upper extremity muscles-remains limited. The aim of this study is to comparatively investigate the effects of LL-BFRT and sham-BFRT, both administered in addition to an aerobic exercise program in individuals diagnosed with stage II and III COPD, on upper extremity muscle strength, upper extremity functional capacity, activities of daily living performance, quality of life, functional exercise capacity, muscle oxygenation, and respiratory parameters. The study is designed as a randomized controlled, single-blind, quasi-experimental interventional trial. The expected outcomes are that LL-BFRT may enhance upper extremity muscle strength and functional capacity, improve activities of daily living and quality of life, and increase exercise tolerance due to its applicability at low mechanical loads. Furthermore, findings related to muscle oxygenation and respiratory parameters are anticipated to provide clinical evidence regarding the physiological effects of LL-BFRT on peripheral muscle adaptations. These results are expected to guide the integration of LL-BFRT as an alternative and safe approach in upper extremity exercise prescription within pulmonary rehabilitation programs, support clinical decision-making processes, and establish a scientific foundation for future research.
