I never aspired to be one of those super athletes. Marathons and triathlons were just never my calling, and it turns out I might be better off for it.
According to an article in the New York Times health section, a recent European study of male runners in their 50s-70s who had run marathons showed that more than one-third had a plaque build-up on their arteries.
After the initial study was released, a different independent study in Canada had contradicting results:
“We showed that that there was none of the damage you’d expect to see” based on the troponin and other cardiac-damage markers in the runners’ blood, he [Davinder S. Jassal, MD, an assistant professor of cardiology, radiology, and physiology at the University of Manitoba medical school in Winnipeg] says. “We strongly believe” that the blood markers “did not indicate true heart damage and any injury was purely temporary.”
This led me to thinking - how much is too much exercise? Really, I think it depends on the body type and amount of training. Someone who has trained their heart for this kind of exertion might have a better long-term reaction to a race of this type. The article agrees, the Canadian study results showed that those who had successfully run previous marathons did now show the damaging results.
According to marathonrookie.com, "it takes a lot more than good old determination and willpower to get you through training and the big day."
Well, I guess I'll just stick to my spin class and elliptical machine and leave the marathons to the pros.
