This brings me to the last point. In English, this means the shorter time you spend on the ground or in the 'load' position, the more powerful the movement. Athletes who can jump the highest, run the fastest, etc. spend a small amount of time on the ground. So, the aim is to be quick off the ground with quick contractions to maintain maximum energy and maximum power. Well, the whole idea of plyometric training is to train your muscles to contract with more strength and quickness making for a more powerful movement.
Plyometric training increases muscle strength and allows for greater power and performance.
The consensus of all the researchers and big wigs in speed and agility training around the world agree that flexibility, aerobic fitness, and strength training are all important and essential components to plyometric training and over all performance. Which means in plain English, plyometric training is not the end all to great athletic performance. It is simply a small portion of the over all picture. In fact, the emphasis here is athletes must have a base of these three components before plyometric training can even be utilized. If the athlete has an inadequate base of flexibility, aerobic fitness, and over all strength, then poor results and injury are inevitable.
