Use a Standing Vertical Jump to Assess Power

Measure standing reach with both hands together overhead, then jump from a standstill and touch as high as possible with both hands; compare jump touch to standing reach. Use a two-handed touch to reduce confounding from shoulder mobility and asymmetry. General target is about 24 inches or higher; if over age 50, closer to 20 inches is acceptable; for females, reduce targets by about 15%.
