Skeletal muscle dysfunction is a prominent manifestation of extrapulmonary effect of chronic obstructive pulmonary disease (COPD). Due to the low physical activity level, systemic inflammation, hypoxia and other reasons, changes in structural and metabolic characteristics that occur in the early stage of the disease, including skeletal muscle mass reduction, cross-sectional muscle area decrease, reduction of total muscle fiber amount, muscle fiber-type shifting, capillary density decrease, mitochondrial dysfunction, etc., may cause weakening of skeletal muscle strength and endurance of patients, affect their exercise performance, increase hospitalization rate and mortality rate, and seriously affect their quality of life. As a unique form of exercise in China, traditional Chinese medical exercise (Gongfa) belongs to the low and moderate intensity aerobic exercise and is an effective exercise rehabilitation method as it can effectively slow down and improve the structural changes of skeletal muscle, improve its muscle strength and enhance its muscle endurance by reducing the level of inflammatory factors and improving blood oxygen level in COPD patients.
