Too Much Exercise May Speed Heart Failure
September 08, 2007
It‘s fairly common knowledge that exercise can be a key part of managing high blood pressure and heart disease, but a new animal study suggests excessive exercise can have the opposite effect.
The study, involving rats with high blood pressure, found that excessive exercise in fact worsened the rats’ blood pressure and progression to heart failure. The reasons for these findings are still unclear, however, and the implications for humans are also uncertain.
According to the researchers, their findings should raise awareness of the potential harm intense exercise might do to people with untreated high blood pressure.
