But isnt soleus activated mainly when the knee is bend,( even slightly) while gastroc is mostly in extension?
unit recruitment in these muscles depends more on task i would say, than knee flexion angle (but also on knee flexion angle). soleus is a postural muscle regardless of knee position because of its high ST fiber composition and fatigue resistance. gastroc is much faster, fatigues easily but produces large twitch amplitudes and has slightly higher firing rates compared to soleus.
