Increasing Pace Of Exercise Better Off For The Heart
October 23, 2002

A new study says a little exercise is good but more is better for preventing heart attacks.

The study compared men who did high-intensity aerobic exercise with those who did low-intensity exercise. The high-intensity group was 17 percent less likely to develop heart disease. The high-intensity group also was 42 percent better off than those who did no running.

The study also says those who weight trained 30 minutes or more a week had a 23 percent lower risk than those who did no weight training.

Weight training's improvements came whether or not the trainer also did high-intensity aerobic activity. So the researchers say it would be best to do both.

The Harvard study is in the Journal of the American Medical Association. The lead researcher is now at Loma Linda University in California.
