Study Notes
- Ankle muscle groups are crucial for walking and running.
- Calf muscle group is active during the propulsive phase of stance.
- Posterior calf muscle group works eccentrically to provide ankle stability.
- Posterior muscles contract to provide power during propulsion phase.
- Anterior muscles work concentrically to stabilize the foot during running.
- Tibialis anterior remains active throughout the running cycle.
- Subtalar joint moves from inversion to eversion when the foot hits the ground.
- Eversion movement is controlled by eccentric contraction of the tibialis posterior.
- Gastrocnemius-soleus produces forces equivalent to 250% of body weight during propulsive phase.
- Posterior muscles move the body horizontally during walking and vertically during running.
