Dr. Gregg Fonarow, a spokesman for the American Heart Association and professor of cardiology at the University of California, Los Angeles, said engaging in regular physical activity is well-established to maintain cardiovascular health and reduce the risk of cardiovascular events, stroke, and premature death.
The American Heart Association and other organizations highly recommend regular physical activity for the primary and secondary prevention of heart disease and stroke, he added.
"These findings suggest similar benefit for similar energy expenditures with exercise regardless of intensity," Fonarow said. "However, for those who are capable of engaging in more vigorous exercise, this may be the more time-efficient strategy."
Other research using data from the walkers' and runners' studies found that for weight loss, running beats walking. That study appears in the April issue of Medicine & Science in Sports & Exercise.
