Perturbation Analysis - Examining Muscle Function During Late Stance of Running

This video shows the potential of three muscle groups (gastrocnemius, soleus, and rectus femoris) to accelerate the body's center of mass during late stance in running. The first segment shows that the gastrocnemius muscle group tends to drive the mass center forward and upward. The second segment shows that the soleus muscle tends to drive the mass center upward and forward. The gastroc and soleus, located in the calf, are the main contributors to propulsion and support during late stance. The final segment shows that the rectus femoris muscle group tends to drive the mass center backwards and upwards.
