Plyometrics is a type of exercise that involves explosive movements to increase strength and power. These exercises typically include jumping, bounding, and hopping, which help improve muscle elasticity and coordination. Athletes often use plyometrics to enhance their performance in sports that require quick bursts of speed and agility. The key principle behind plyometrics is the stretch-shortening cycle, where muscles are rapidly stretched and then contracted. This process helps develop fast-twitch muscle fibers, which are essential for activities like sprinting and jumping. Incorporating plyometric training can lead to improved athletic performance and overall fitness.
