What is plyometrics primarily known for in resistance training?

Plyometrics is primarily known for its ability to enhance explosive power and speed through rapid muscle stretching followed by immediate contraction. This method utilizes the stretch-shortening cycle of muscles, where a muscle is first stretched (eccentric action) and then rapidly contracted (concentric action). The quick transition between these phases helps improve the body's overall power, as it allows for a more forceful contraction due to the elastic energy stored in the muscles and tendons during the stretching phase.

The emphasis on muscle stretching prior to contraction is integral to this technique, as it prepares the muscles for rapid and powerful movements commonly found in various sports and physical activities. This characteristic distinguishes plyometric exercises from other forms of training, such as flexibility work, which aims to increase the range of motion, or pure strength training, which focuses on maximal force production without necessarily involving explosive movements.
