The gastrocnemius operates in a second-class lever system. In this type of system, the resistance is located between the effort and the fulcrum. In the case of the gastrocnemius, the resistance is the weight of the body (or an external load), the fulcrum is the ankle joint, and the effort is applied by the muscle to lift the body or load up on to the toes.
