Stretch shortening cycle

A stretch-shortening cycle (SSC) is a natural muscle function in which there is a rapid transitioning from an eccentric contraction (lengthening under load) to a concentric contraction (shortening) of the same muscle, storing elastic energy during the stretch and releasing it during the shortening. This process enhances force and power output, and make movements more explosive and efficient. This function is a primary principle in plyometrics, sprinting, jumping and throwing.
