Plyometrics
Plyometrics
Plyometrics (pronounced: ply-oh-MET-riks), also known as jump training or plyos, are exercises in which muscles exert maximum force in short intervals of time, with the goal of increasing power (speed-strength). This training focuses on learning to move from a muscle extension to a contraction in a rapid or "explosive" manner, such as in specialized repeated jumping.
Etymology
The term "plyometrics" was coined in 1975 by Fred Wilt, a former American track and field coach. The word originates from the Greek words "pleythyein" (to increase) and "metric" (to measure), which together mean "measurable increase".
