Maximum grip strength of all limbs (A and B) or forelimbs only (C and D) with absolute (A and C) and change data (B and D) of male C57BL/6 mice exposed to physical inactivity (PIA) as hindlimb unloading (HU) or as early life ambulatory controls (CON) in the early postnatal period (days P28–42) examined in early adulthood (∼5 mo/P150) as ambulatory controls (AMB) or mice exposed to HU or HU + 7 days of reloading (RL7). Data are means ± SE. Different letters within each experimental group (CON, PIA) indicate differences (P < 0.05) across adult experimental conditions (AMB, HU, RL7). #P < 0.05 vs. CON in that condition. For % change data *P < 0.05 is a significant change.
