Marathon Running Can Tax the Heart

Less-Fit Runners Could Develop Temporary Damage to the Heart During a Marathon, Study Finds

Proper Training Is Essential for Marathon Runners continued...

This is important. "If you say I am training to run the New York City marathon in seven hours, they will look at you differently and may do different tests to assess your cardiac fitness to do the event," he says.

The International Marathon Medical Directors Association recommends taking a baby aspirin on the day of the race to lower heart risks (assuming aspirin is advisable) and limiting caffeine to less than 200 milligrams before or during the race.

That said, marathon running is not for everyone. "If you are not appropriately trained and screened, you should not run," Maharam says.

This study was presented at a medical conference. The findings should be considered preliminary as they have not yet undergone the "peer review" process, in which outside experts scrutinize the data prior to publication in a medical journal.
