Plyometric training can act as the bridge between strength, power, speed and skill.
Plyometric training utilizes the stretch reflex mechanism in the muscle to improve the reaction time of the nervous system in that muscle. It results in an increase the overall neural stimulation of the muscle and therefore increase in force output.
Plyometrics work by quickly stretching the muscle (eccentric) followed by a very quick muscle contraction (concentric).
The GOAL of plyometric training is to develop the power and speed that is specific to a sport.
