If an elderly patient experiences a hip fracture following a fall, which mechanism most directly contributes to the prolonged recovery specifically due to sarcopenia?

💡 Explanation

Sarcopenia involves a decline in muscle mass and function. Because muscle regeneration relies on protein synthesis, sarcopenia impairs the muscle's ability to recover after an injury such as a hip fracture. Therefore, reduced protein synthesis delays the recovery process, rather than the other options which don't directly link to muscle recovery.
