How to Properly Warm Up Prior To Exercise: Static vs. Dynamic Stretching

I am teaming up with local P.T., Dr. Eric Broadworth, to work on a handful of new projects in the near future. These projects will involve cutting through the B.S. and dispelling myths when it comes to performance, health and longevity, and strength progression through your life. You can check out more of his credentials, areas of expertise, and performance-related topics on his website. This article is reposted from his website with his permission.

People all too often continue to warm up prior to exercise, or an athletic competition, with static stretching. Static stretching means that you hold a stretch for a prolonged period of time, such as 30 to 60 seconds. In past decades, it was believed that static stretching prior to exercise was necessary in order to help prevent injury and improve performance. However, research over the past 20 years has demonstrated that this prior belief was incorrect and that a dynamic warm-up, or dynamic stretching, is necessary in both preventing injury as well as improving performance.

 

A common warm-up utilizing static stretching includes a brief period of low-intensity aerobic activity (such as riding a bike) and static stretching. Low-intensity aerobic activity may elevate muscle and core temperature, decrease stiffness to muscle tissue and increase metabolism, blood circulation and nerve conduction. The purpose of static stretching is to improve flexibility, which has been indicated as an injury risk factor for athletes with decreased flexibility. While long-term flexibility training is important to maintain healthy muscle tissue length and reduce injury risk for specific individuals, there is no evidence that static stretching, immediately before activity, will significantly reduce muscle injury rates. Multiple studies, in fact, have no effect on performance and may actually cause performance deficits by decreasing strength, power; balance, reaction and movement time; vertical jump height; and sprint performance.

 

A dynamic warm-up utilizes dynamic stretching and jump training which involves specific movements that will be used throughout the exercise session. A combination of these techniques prepares the body for performance by improving core and muscle temperature, enhancing function of the nervous system, and using similar movements that occur during subsequent exercise. Research has concluded that dynamic warm-up can significantly improve power and agility, sprinting performance, vertical jump, and long jump.

 

It is important to incorporate up to date research in athletics and fitness if we want to get the best results and it is clearly stated, multiple times, that a dynamic warm-up has significance in decreasing the risk of injury with performance, while also improving overall performance. Instead of using static stretching to warm up, use it after exercise when cooling down or in any setting other than a warm-up for exercise. If you do not know how to properly incorporate a dynamic warm-up, you should seek instruction from a qualified professional such as a physical therapist, athletic trainer or certified personal trainer.
