With many of us contemplating marathons or other prolonged endurance
events in 2016, we, our spouses and other family members most likely have
wondered whether such strenuous training could be harmful to our hearts.
Could any of us, in making ambitious resolutions, exercise too much?
.
A newly published scientific review offers both reassurance and some
caution. It found that while most athletes hearts can withstand most
exercise, there are exceptions. For some people in seemingly good health,
heavy loads of exercise might be problematic. Thats why all of us who work
out should be as informed as possible about our familys cardiac history
and our own potential genetic risks.
.
Exercise, of course, is in general extremely beneficial for heart health.
Dozens of large-scale epidemiological studies have found that people who
exercise in any amount, whether five minutes a day or two hours a day or
more, are much less likely to develop or die from heart disease than
people who are sedentary.
.
But these studies, while encouraging, contain a disquieting subtext. Their
plotted data typically shows some type of bell curve to the heart benefits
from exercise, meaning that the more people work out, the less they are at
risk of cardiac problems up to a point, and then the benefits plateau or
decline.
.
To some scientists, that finding made little intuitive sense. If a little
exercise is good for the heart, why shouldnt more be continually better?

.
Perhaps most surprising, older marathon runners can be just as susceptible
as their sedentary counterparts to atherosclerosis, or the buildup of
dangerous plaques in the arteries, the studies show. Strenuous exercise
does not prevent these plaques in people who are predisposed by heredity
or lifestyle to the condition.
.
The act of exercising, however, may increase the risk that the plaques
will rupture, precipitating a heart attack. Someone with atherosclerosis
is more likely, studies show, to have a heart attack while running than
while sitting quietly.
.
But many older athletes with atherosclerosis have no idea they suffer from
the condition, which often causes few symptoms.
