Many athletes and trainers use plyometric jumping exercises to build power and speed, improve coordination and agility and effectively improve sports performance. It's also important to recognize that these are high risk exercises and if performed incorrectly or performed without a solid base of training, plyometrics can increase the risk of injury.
Plyometric training involves training the nerve cells to simulate a specific pattern of muscle contraction, so the muscle generates as strong a contraction as possible in the shortest amount of time. A plyometric contraction initially involves a rapid muscle lengthening movement (eccentric phase), followed by a short resting phase (amortisation phase), then an explosive muscle shortening movement (concentric phase), which enables muscles to work together in executing the particular motion. Traditional weight training exercises do not always allow the athlete to use the explosive speed or the movements needed to develop sport specific power.
However, whether you’re a competitive sportsperson or not, plyometrics can add a valuable dimension to your training program, not to mention it is also great for you. It is good for your heart and circulation, and also helps to develop flexibility and speed. Another positive is that you can do it anywhere you are most comfortable in your house or out on the lawn as you don’t need much equipment other than your workout gear and yourself.
