Plyometrics, also called plyometric exercises, plyos and jump training, is an exercise technique that targets muscles to increase speed, strength and power. This technique is useful in improving the performance of athletes who perform a lot of running and jumping.
Plyometrics uses rapid, repetitive movements that are typically performed from a contracted muscle or crouched position into an extended one and back to the starting position.
Some examples of plyometric exercises include depth jumps, which involves jumping onto a bench, and medicine ball chest passes.
The American Council on Exercise states that plyometric training has been shown to improve athletic performance. However, since there is a risk of injury when doing plyometric exercises, if the muscles lack sufficient strength, consult a physician before attempting this type of training.
