(b) The amortization phase is the transition from eccentric to concentric phases; it is quick and without movement. To do this, they tap into an involuntary "reflexive" contraction that occurs during the stretch-shortening cycle when athletes change direction.
Resistance exercises characterized by maximal or near maximal rates of force development or by high accelerations, usually referred to as "explosive exercises," are effective for enhancing . . The phases of the stretch-shortening cycle are similar to traditional contraction types but with amortization in place of isometric holds.
