Which is an eccentric function of the gastrocnemius?

Question

Quizplus · Accepted Answer

The gastrocnemius is a biarticular muscle that crosses two joints, the ankle and the knee. It is responsible for plantarflexion of the foot at the ankle joint and knee flexion at the knee joint. During knee extension, the gastrocnemius contracts eccentrically to slow down the movement and prevent hyperextension. Therefore, the eccentric function of the gastrocnemius is to restrain/slows extension of the leg at the knee joint, making B the correct answer. The other options do not relate to the function of the gastrocnemius.
