Plyometric

Plyometric: exercises done with the intent of increasing power that include a rapidly loaded eccentric, followed by a short "amortization phase" (isometric contraction) and rapid concentric contraction (1). Plyometric exercise is presumed to increase power by increasing or coordinating the contribution of myotatic reflex (stretch reflex), elastic recoil of eccentrically loaded connective tissues, and optimization of motor unit recruitment.

• History: Verkhoshanski, a track and field coach in Russia developed a system of "shock training" or "jump training" (2,3). Fred Wilt, a former Purdue University women's track coach first coined the term plyometrics in 1975 to describe Verkhoshanki's training method, and aided in popularizing the term and training in the United States (4). The word plyometrics is derived from the Greek, plythein or plyo - to increase, and metric to measure.
