Joint research effort determines the impact of light exercise on heart conditions
by Mike Adams, the Health Ranger, NaturalNews Editor
In an animal study, researchers at the University of Colorado at Boulder and Ohio State University found that heart failure can be delayed by low-intensity exercise.
A study in treadmill-running rats suggests that low-intensity exercise can delay heart failure in humans and extend the lives of people with congestive heart failure.
Rats with an animal model of congestive heart failure (CHF) were exercised on treadmills at speeds equal to brisk walking in humans.
"We found that low-intensity exercise training markedly delayed the onset of overt CHF without a reduction in antecedent hypertension," concluded researchers at the University of Colorado at Boulder and Ohio State University, in Columbus.
"Additionally, we found that some, but not all, of the classic cellular and systemic physiological alterations normally associated with the development of overt CHF were attenuated with exercise training," the study authors added.
"The key findings in this study are that (1) exercise can delay the onset of decompensated heart failure and improve survivability and (2) this effect is strongly dependent on the level of intensity of the exercise.
You can push the level over the edge quickly," laboratory director Russell L. Moore said in a prepared statement.
"Not that long ago, clinicians were afraid to even suggest a little exercise in patients with CHF.
However, our study, along with several human studies, shows a definite trend indicating that moderate intensity exercise has a potential role in stemming the downward spiral in heart failure," Moore said.
