Which of the following is NOT a type of stretching?

Plyometric stretching is primarily associated with explosive movements and is not classified as a distinct stretching technique. It involves rapid and powerful body movements that aim to increase muscle power and improve athletic performance by utilizing the stretch-shortening cycle of muscles. While plyometric exercises can involve stretching components, the goal is not to stretch the muscles in the same way static, dynamic, or ballistic stretching aim to improve flexibility or range of motion.

Static stretching involves holding a stretch position for a prolonged period to enhance flexibility, dynamic stretching incorporates controlled movements that improve range of motion and warm up muscles, and ballistic stretching uses the momentum of a moving body to force a stretch. Each of these types plays a specific role in fitness routines, highlighting how plyometric stretching diverges from the traditional definitions of stretching techniques.
