Distal Femoral Metaphysis μCT results. Representative regions of interest of trabecular bone for Adult (left) and Aged (right) femurs at baseline. Adult rats exhibited greater BV/TV, Tb.N, and reduced Tb.Sp than Aged rats. 14 days of hindlimb unloading resulted in significant loss of trabecular bone in Adult rats, but no significant decrease in Aged rats. By day 3 of reloading, Adult rats had recovered trabecular bone volume, while Aged rats exhibited continued loss of bone. Brackets indicate significant differences between groups (p < 0.05). Asterisks (*) indicate a main effect of age in a parameter between Adult and Aged animals (p < 0.05)
