Antifrail: Why Muscle (Power) Matters in Aging

Apply It! • Reductions in muscle power begin earlier in the life course and occur at a greater rate when compared to declines in muscle strength. • Power training in older adults may lead to a greater improvement in physical function than traditional resistance training alone. • Muscle power is a product of force and velocity — if either force or velocity are underdosed, improvements in muscle power are less likely to be realized. •Higher-functioning older adults may show functional performance plateaus; however, having a reserve of muscle power may still be important.
