Figure 3

Simulated gastrocnemius (GAS) and soleus (SOL) mechanics over a gait cycle as a function of altered peak tendon strain at maximal isometric force (3.3 % – 11.6 %). Fiber and tendon powers were normalized to body mass and compared to the power developed in the whole muscle-tendon unit (MTU); fiber length was normalized to its optimal length (Lo). Vertical dashed lines indicate, respectively, the contralateral toe-off and heel strike and the ipsilateral toe-off, and shaded areas the stretching and shortening periods of each muscle during the stance phase.
