Differences in the active (A) and passive (B) torque-angle relationships between young (n = 10 pre- and post-cast; n = 5 at 4 wk recovery) and older adult rats (n = 11 pre- and post-cast; n = 6 at 4 wk recovery) and across time. *Difference from pre-cast (P < 0.05). †Difference from post-cast (P < 0.05). #Difference between young and old (P < 0.05). Same letters denote no significant difference within a time point and age group (P > 0.05)
