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.."

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.

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.

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,
