Dynamic stretching has become increasingly popular stretching technique for athletes of all ages. Dynamic stretching is a controlled movement that involves an active range of motion for each joint in the body. It involves stretching while the athletes are actively moving. Dynamic stretching is used to improve flexibility in motion and does so by resembling movements you would normally make in your sport. In comparison, static dynamic stretching involves an athlete stretching their muscles in a stationary position. Track athletes normally have extensive warm up and stretch routines before their meets, and believe that these stretches lead to enhanced performance and a decrease in injury. By performing dynamic stretches instead of

There are mixed reviews of whether dynamic stretching is actually beneficial for athletes. In the study by Behm and Chaouachi (2011) they tested the duration of stretching and if that affects the effectiveness of dynamic stretches and static stretches. They found that static stretching provides benefits in some cases such as slower velocity contractions and those over a longer duration. Dynamic stretching according to this study had little to no effect on performance for the athletes, especially over long distances. They found the key to stretching is to incorporate a high intensity aerobic activity followed by dynamic stretching and then finished with a sport specific dynamic activity (Behm and Chaouachi, 2011).
In the Chaouachi et al. (2010) study they investigated the effects of dynamic stretching and static stretching alone and in combination on an athletes agility, sprinting, and jump performance. This study found that static stretching did not affect performance and dynamic stretching didn’t enhance or harm performance. They too found that either type of stretching is beneficial if followed by an aerobic activity and a sport specific high intensity dynamic activity.
The study by Turki et al. (2012) looked at the effects of different intensities of dynamic stretching on two sprint distances for track athletes.
