Measures of muscle performance relevant to older adults

Muscle performance measure	Description
Strength	• Maximum capacity to generate force or tension • Can be assessed using isometric handgrip dynamometry or a more dynamic measure of the 1-repetition maximum
Power	• Rate of physical work performance • Has a component of velocity that may be have clinical relevance for older adults • Peak power is more closely associated with declines in physical function than muscle strength in older adults
Endurance	• Ability to maintain a specific force output • Related to functional capacity in older adults.
