Fig. 1. Mean time-histories of selected variables from a single animal normalized to the total stance time for a variety of locomotor conditions. (A) MG muscle-tendon length, (B) SOL muscle-tendon length, (C) MG velocity, (D) SOL velocity (shortening is positive, stretching is negative), (E) MG muscle force, (F) SOL muscle force, (G) resultant ankle joint moment (extensor moments are positive, flexor moments are negative), (H) resultant knee joint moment (extensor moments are positive, flexor moments are negative).
