Definition:
Plyometric training is an intense, advanced form of exercise in which the muscles are first stretched, then contracted (the pre-stretching makes the muscle contract with greater force). Plyometric movements are powerful and high-impact, although the impact should be controlled as much as possible. Plyometric training requires both strength and endurance. Common plyometric training exercises include various jumps and hops, sometimes using obstacles such as steps or cones.
The American College of Sports Medicine says that plyometric training is both safe and worthwhile for kids and teens "if age-appropriate guidelines are followed, qualified instruction is available, and individual concerns are addressed."
