NEW research on "excessive exercise" in untreated hi-blood pressure & heart failure!
Though exercise can be a key part of managing high blood pressure
and heart disease, new animal research suggests there can be too
much of a good thing.
researchers found that excessive
exercise worsened high blood pressure and progression to heart
failure in rats with high blood pressure. the findings "should raise our
awareness" of the potential harm intense exercise might do to people
with untreated high blood pressure. The reasons for the findings are unclear, according to the study
authors, but it's likely that the rats "simply exercised too much."
"uncontrolled and excessive
exercise" may negatively affect the heart in people with high blood
pressure, potentially speeding the onset of heart failure, according
to Sarma and Schulze. "Defining the fine line between beneficial and detrimental
effects of exercise requires further study," the editorialists
conclude.
