Time histories from touch down to toe-off of joint angles (A and F), ankle moment vs. ankle angle change from touch down to midstance (B and G), and muscle force vs. muscle-tendon complex (MTC) length change for m. soleus (SO; C and H), m. gastrocnemius (GA; D and I), and m. tibialis anterior (TA; E and J). Arrows indicate the progression in time.
