Age-related muscle decay involves whole-tissue changes, not just fiber shrinkage
Sarcopenia (age-related muscle weakness) develops through multiple interconnected changes in the muscle tissue environment—including inflammation, cellular damage, and reduced repair capacity—that form a self-reinforcing cycle, rather than from muscle fiber shrinkage alone.
Why it matters: Understanding that sarcopenia involves tissue-wide environmental changes could redirect treatment toward earlier, potentially reversible stages rather than only end-stage muscle loss.
Keep in mind: This is a review article summarizing existing evidence, not a new experimental study testing specific treatments or measuring life extension in humans.
