The reflex arc creates the contraction of the muscle, which is predominately isometric. Further deceleration of the body’s movement then loads the connective tissue, which eventually reaches a point at which the force required to lengthen it farther has been absorbed by the increasing stiffness of the elastic fiber. Once it reaches the point at whi

Most muscles will fire most efficiently and powerfully if they are preloaded into a moderate stretch before contracting. This allows the muscle to take advantage of elastic recoil and stretch reflexes.
