Aftermath of a Marathon: Your Blood Panels Look Like You Just Had A Mild Heart Attack???

Okay, I'm not going to pretend to secretly hope to be one of those individuals who loses a ton of weight and then runs a marathon--an improved brisk walking pace on a 5k is more my goal (and the ability to do some more advanced yoga).

According to several recent studies:

Last year studies were conducted in Australia, Canada, and Germany measuring the effect running a marathon had on the hearts of elite to novice runners. Tests were given on the participants immediately before and after running a marathon. The end findings were similar across the board — the participants showed marked blood indicators of cardiac damage.

“We measure those same blood markers when someone comes in to the emergency room and we suspect a heart attack,” says Davinder S. Jassal, MD, an assistant professor of cardiology, radiology, and physiology at the University of Manitoba as told to the New York Times. Blood profiles like those displayed by the runners are similar to those in a very mild heart attack.”

The coverage of the study didn't say whether post-race day blood work was used to determine the long-term damage of marathon running. The myth behind the marathon includes the tidbit that the man who ran the 26 mile distance, Tippets, dropped dead after delivering his message in Athens of the Greek victory over the Persians--okay, to be fair, he had allegedly also run 140 miles in 36 hours to beg the Spartans for aid and then back again, then fought in the battle, and then run the last 26 miles after victory--so, the marathon distance alone was not the legendary culprit behind his death).

Regardless, with triathlons, ultra-triathlons (extreme long-distance events covering 320 mile distances) and other extreme sports out there today, its important to remember the human body has limits. Many runners might take offense at this studies results because it calls into question how "healthy" extreme demonstrations of "fitness" can be. I say, evidenced based scientific research is important and should be used to give individuals a good understanding of the risk and rewards of endurance training and race-day impacts on the body.

Challenge: do something for fitness this weekend that you haven't done in a while. I'll do the same.

  1. I hate to be the voice of reason. Before any weight loss or exercise regieme you should consult a doctor.

    I know that I started walking for weight loss. After 8 months. My feet were going numb as I sat. Spoke with my doctor. I explained my exercise regieme and was told this problem could be solved with more adequate strecthing at the start and end of each day, plus additional strecthes during workout.

    So it it my reminder has you move into healthy exercise. Move slow and steady. Don't do the couch to 5K in 8 weeks unless you started off height/weight chart thin and consulted a doctor.
