Dynamic Stretching - Why Dynamic Stretching?

Why Dynamic Stretching?

Dynamic stretching is a technique gaining in popularity due to recent studies which show that traditional static stretching techniques do little to increase flexibility or reduce injury when performed before a workout. In fact, many studies show that static stretches actually have a detrimental effect on explosive movements and strength output. There are two types of flexibility receptors, a static receptor, which measures magnitude and a dynamic receptor, which measure speed and magnitude. As one would expect, dynamic activities that require movement, such as running, jumping, or kicking use the dynamic receptor to limit flexibility. Therefore, a dynamic stretch that stresses the dynamic receptor is more beneficial when preparing for a warm-up when performing a dynamic activity. Dynamic stretching also includes constant motion throughout the warm-up, which maintains the core body temperature, whereas static stretching can see a drop in temperature of several degrees. Another benefit of dynamic stretching is that it prepares the muscles and joints in a more specific manner since the body is going through motions it will likely repeat in the workout. It also helps the nervous system and motor ability since dynamic motions do more to develop those areas than static stretches. It is important to note that although many studies show the lack of benefit of static stretching before a workout, there is still much data to support the benefits of static stretching after a workout.
