Muscle Matters: Bridging the Gap Between Terminology of Age-Related Muscle Loss and Exercise Interventions

Key Points

• Age-related loss of muscle is associated with adverse health outcomes leading to disability and higher risk of mortality.
• Various criteria used to define sarcopenia have involved not only muscle mass but also muscle function.
• Age-related muscle loss terminology should follow specification of its muscle variable measurements: mass, strength, or power, encouraging prescription of targeted exercise interventions for each specific age-related muscle variable loss.
