From a Science Daily online release:
“People with heart failure cannot do everything that a healthy individual can, so the question becomes how much exercise can they handle and what type of impact will it have on their health,” Emter said. “We found that regardless of intensity level, some type of physical activity was good for heart health compared to no exercise at all.”
Now, research from the University of Missouri has found exercise can improve the health of blood vessels in the heart for people with heart failure. The finding is based on a study looking at swine, which have very similar blood vessels and heart muscles — both structurally and functionally — as humans.
