This narrative review discusses the mechanisms of cancer cachexia, its impact on respiratory muscle function, and highlights exercise as a relatively underexplored potential intervention.
It identifies a research gap, noting that most studies focus on limb muscles, not the respiratory musculature, which atrophy and dysfunction contribute to respiratory failure and mortality. The review outlines the mechanistic basis of cachexia, emphasizing inflammatory mediators, and explores the potential of exercise as an intervention. It suggests exercise may support muscle via antioxidant, anti-inflammatory, and metabolic effects. The authors propose that pre-clinical mouse models provide a platform for developing multi-modal therapeutic strategies combining pharmacology, nutrition, and exercise to protect respiratory muscles. Limitations include the pre-clinical focus and the need for further human-relevant research.
