We believe that authors have meritoriously focused their attention on a highly relevant topic, which is the skeletal muscle decline in patients with COPD. Sarcopenia represents a condition exposing older persons to the risk of disability and negative health-related outcomes. Since respiratory conditions, including COPD, may directly (eg, through poor peripheral oxygenation, inflammation, hypercatabolic state) and indirectly (eg, inducing sedentary behaviours) affect the skeletal muscle, more attention should be given to sarcopenia. This implicitly suggests the need …
