Health Concerns for Endurance Athletes

Posted by & filed under Fitness Programs.

The incidence of scar tissue appears to be related to athletes who do long distance running or repeated excessive exercise over a period of time.  The accumulation of the scar tissue on the heart can lead to a hardening of the heart muscle muscles, a higher risk of atrial fibrillation and arrhythmias, and early aging of the heart.

In the Mayo Clinic study, over 10% of the marathon runners tested had developed myocardial fibrosis.  This heart damage suffered by elite athletes puts a new light on how much exercise is necessary without doing damage to your health.  In the past, it was thought that the more exercise someone does, the better it would be for their conditioning and health.

There have been some deaths of marathon and ultra marathon runners who were discovered to have suffered from enlarged hearts and arrthymia, after  an autopsy was done.  Micah True, who was an ultra marathon runner and had a training regimen that included running 50 to 100 miles, died of an episode of arrhythmia.  After an autopsy was done, the results showed that True had scar tissue and an enlarged heart.

While there are no set parameters for how much exercise is too much, the doctors doing the survey suggested to reduce your endurance activities.  If you are a marathon runner, the doctors recommended doing less that five marathons a year and reduce the training distances that you train every week.

If you participate in endurance fitness activities, you don’t have to abandon your regimen, but try and cut back on your weekly amount of training.  Make sure you have time to recuperate from your conditioning.

If you are just starting out on an exercise plan, your goal should  be to get a good workout that will boost your metabolism and won’t put undue stress on your body.  Spending twenty minutes on a workout is all you need as long as you increase your heartrate and the workout is mildly strenuous.  A walking program is a great way to start.

While most endurance athletes are in far better shape than a couch potato, the key to a healthy exercise program seems to be moderation.  You don’t need to go to excesses to keep your body in peak condition.  Sometimes less is better.

    I ran a couple marathons and my body didn’t like it. Now I guess I know why. I do know several people who are addicted to the high they get from running marathons. Sounds like the risks should make you reconsider how much you run.

    I never did like endurance sports and prefer short workout programs. Now it seems I made the right choice and can avoid overstressing my body. Thirty minutes a day is all I need.

    I can’t believe that no research had been done earlier to see if running in marathons could damage your heart. I wonder how many marathoners are now dealing with heart problems . Better late than never I guess.
