Muscle aging involves loss of resilience from multiple cellular breakdowns
Aging muscle weakens through coordinated damage across multiple cell types—not just muscle fiber loss—involving inflammation, faulty protein repair, and mitochondrial problems. Exercise and nutrition are the established treatments, while newer approaches targeting these cellular issues are being studied.
Why it matters: Muscle weakness causes frailty and loss of independence in older adults, so understanding its causes could guide better treatments.
Keep in mind: This is a review of existing research, not a study showing what interventions actually work to slow muscle aging in humans.
