How Much Running is Too Much?

Excessive RunningResearch from The Cooper Institute has shown that the value of exercise is overwhelmingly good; however, studies also show that more is not always better. 

How much running is too much? This a very controversial question, but Kenneth H. Cooper, MD, MPH, has long said that if you are running more than 15 miles a week, you are doing it for a reason other than health. When you run beyond 15 miles a week, there is a fairly sharp increase of muscular skeletal problems in areas such as your knees and hips.

If you are training for a vigorous physical activity like endurance running, it’s important to make sure that you are not damaging your body tissues.  When you are an endurance athlete, your body can be compromised from oxidative stress as you lose essential nutrients through sweat and increased oxygen consumption. When this occurs, your body can begin to produce dangerous free radicals, which are a by-product from the metabolism of oxygen. An increase in these free radicals throughout your body can result in soreness, DNA damage, cancer, muscle tissue damage and other degenerative diseases.

Running 30+ miles per week may be linked to scarring of the heart due to a lack of oxygen and free radical damage. If you’re running this much, Dr. Cooper says it is imperative that you supplement your body with the proper nutrients to suppress any DNA damage from free radicals. Elite athletes can benefit by taking the proper dosages of vitamins E, C and beta carotene. Dr. Cooper recommends taking 400 international units (IU) of vitamin E twice a day to decrease risks associated with excess running. The Cooper Complete Elite Athlete formula provides the nutrients needed to suppress free radical damage.

Over the years, there have been reports of sudden deaths while endurance athletes were running. Dr. Cooper stresses that this is a rarity, because the majority of athletes who suddenly die while running often have an underlying congenital heart defect. This defect can typically be detected from an EKG.

Our bodies were designed to be fit and active. When you put this topic into perspective, you can clearly see that the proven benefits of exercise outweigh the risks associated it. If you are an endurance athlete, consult your physician to ensure that you are receiving the proper supplementation to stay healthy while you train.
