Age-related differences across the adult lifespan: a comparison of six field assessments of physical function

This study evaluated and compared the ability of six field tests: handgrip strength (HGS), maximal gait speed (MGS) over a 10-m course, 5-repetition sit-to-stand power (STSP), timed up and go (TUG), countermovement jump (CMJ), and stair climbing power (SCP) to detect age-related changes in physical and muscle function across adulthood.
