What is the action of the gastrocnemius muscle?

Actions of the gastrocnemius muscle include pulling the heel up and extending the foot downward. It also provides the force necessary for running and jumping.

The gastrocnemius muscle is also known as the leg tricep. It lies between the back of the thigh or femur to the patella or kneecap before joining the soleus muscle. The gastrocnemius muscle is attached to the Achilles tendon at the heel. The gastrocnemius muscle assists in actions that involve fast movements. This is due to the presence of white muscle fibers in the muscle. The gastrocnemius muscle plays a smaller role in walking and standing.
