This type of stretching does little to relax or lengthen connective tissue or muscle tissue.

Ballistic stretching is a quick and repetitive stretch that does not effectively lengthen muscles or connective tissue like fascia. It is often used be athletes immediately prior to competing as part of a warmup. This is because the energy (tension) stored in connective tissue is a component of high performance. Ballistic stretching is a form of dynamic stretching.
