What is the action of plantarflexion?

Plantarflexion refers to the action of pointing the toes downward away from the body. This movement primarily involves the muscles of the calf, particularly the gastrocnemius and soleus, which contract to allow the foot to push down. During activities such as walking or standing on tiptoe, plantarflexion is essential for locomotion and stability.

This movement contrasts with dorsiflexion, where the toes are lifted upwards towards the shin. The description of plantarflexion aligns perfectly with the action of extending the foot at the ankle joint so that the toes move further away from the front of the leg. Therefore, it is critical to understanding how movements in the lower extremities contribute to various exercises and functional activities.
