sec
The series elastic component of a muscle is part of the mechanical model of plyometric exercise. The tendons attached to the muscle constitute the majority of the series elastic component. When the musculotendinous unit is stretched, as in eccentric muscle action, the SEC acts as a spring and is lengthened; as it lengthens, elastic energy is stored. IF the muscle begins a concentric action immediately after the eccentric actiopm, the stored energy is released, allowing the SEC to contribute to total force production by naturally returning the muscle and tendons to their unstretched configuration.
liquid-filled columns or tubes (similar to household barometers) and elastic pressure elements, which operate on spring-action, diaphragm, or bellows principles
Glutes and quads contract when you stand, lengthen when you squat. So it's eccentric for those muscles. There are a bunch of muscles involved in a squat, some may be concentric.

A concentric movement would be flexing the elbow and curling a dumbbell towards the shoulder, an eccentric contraction would be the opposite movement ie bringing the dumbbell back down towards the thigh.
When the elastic is drawn back by the action of work done by the boy, potential energy is at a maximum, stored in the elastic. When it is released most of the energy is converted into kinetic energy of the stone.

Elastic Clause: To make all laws which shall be necessary and proper for carrying into execution the foregoing powers. The Elastic Clause allows future generations to expand the meaning of the Comstitution. Congress can take action on issues not to spelled out in the Constitution.
Elasticity is a physical propery of materials which permit the return to the initial state after the cessation of a deforming action.
