All that exercise could kill you . . .

[D.]

As in most everything, too much exercise--normally a very good
thing-- can actually be bad for you.

Even though a key part of managing high blood pressure and
heart disease, new animal research suggests there CAN be too
much of this good thing. The August edition of the journal
"Hypertension" reports that researchers from the University of
South Dakota found in experiments with rats that excessive
exercise worsened high blood pressure and led to progression
to heart failure in rats with high blood pressure.

Because of all the previous findings about the benefits of
exercise, these new findings in rats are unexpected. An
editorial published with the study says that the implications
for humans are not yet certain.
Dr. Paul Christian Schulze, of Boston University Medical
Center, and Satyam Sarma of Brown University warn that the
findings "should raise our awareness" of the potential
harm intense exercise might do to people with untreated
high blood pressure.

Researchers found that rats which lived with a running wheel
tended to exercise excessively. The results, over time, were
structural abnormalities in the heart and a reduced pumping
ability -- all of which were worse in the active animals than
in the sedentary ones. It's likely that the rats "simply
exercised too much."

It's obvious that scientists and clinicians now need to focus
on defining the fine line between beneficial and detrimental
effects of exercise.

Good news! Well, actually very sad news. The average American
isn't anywhere near the lower end of the scale for the
recommended amount of daily exercise, so this report can get
filed in the trash.

I'd say that I generally agree with you, except for the throw
the study in the trash part. I think you need to find the
healthy balance for exercise. This report really shocked a lot
of scientists, because they found that the hypertensive may
actually push their heart into cardiac damage if they pass
that line in the sand. It's really hard to perform that kind
of study on humans, though!

It's probably good that science is exploring this, because
those with high blood pressure who jump into an exercise
regimen thinking "the more, the better" may find themselves
looking super healthy on the outside, but actually candidates
for a stroke or heart problems down the road. I think they
need to do more research on this, not less,

Dave,

I was actually half-joking about throwing this report in the
trash. While this info may be helpful for some elite athletes,
I say the money for this study would be MUCH better spent
trying to education the masses on proper nutrition, so we
don't meet the recent projection that 75% of Americans will be
obese/overweight by 2015. Another reason is to not to feed
Americans with ANY thoughts that exercise could be bad for
you. Because for many people all they need to hear is some
twisted comment from this study and they'll quickly pledge to
never park more than 5 parking spaces away from the front
doors of Walmart ever again -- "Oh my god, walking will make
me perspire and perspiration is the onset of death.."

well, O.K., but maybe if the rats had a good book to read and
were able to take in a movie now and then the results might be
different. Very few of us are confined to a cage with no
diversion other than a piece of exercise equipment. Maybe the
rats on the wheel think that by running long distances they
will escape and so get frustrated thus raising their blood
pressures. Dolores
P.S. Ornish reports the death of one man on his program who
over exercised. I think he attributed it to the man not
being in touch with his emotions or something like that.
It is also possible to drop dead exercising like Jim
Fixx who ate a high fat diet, denying that anyone could
die from heart disease who could run a marathon.
