PLYOMETRICS:
The Antithesis of Passive Stretches
According to Mel C. Siff PhD:
“Plyometrics are some of the most misunderstood methods of training. Even in the world of sports training among top coaches, this Russian ‘secret’ of training is frequently poorly defined and wrongly applied.”
The term "Plyometric" has come to include any exercise where the muscle is contracted eccentrically then immediately (like split-second lighting-fast), contracted concentrically.


The most well known example of a plyometric exercise is the depth jump...

Stretch Reflex (a.k.a. Myotatic Reflex, or Deep Tendon Reflex)
Clinical Testing of the stretch reflex:
Impact to a tendon produces a very quick, small stretch of the muscle. Many of the spindles in the muscle are excited simultaneously, producing a discharge of sensory neurons that act convergently upon the motor neurons. This results in a brief rapid twitch.
Translation: Ya Know when your doctor smacks your knee with that goofy little triangular rubber mallet and your foot flies up in the air...well that is an illustration of the stretch reflex at work.
However, it is not the purpose of this page to teach you about plyometric training. The purpose of this page is to let you know that
