WEDNESDAY, Oct. 5 (HealthDay News) -- Three hours of vigorous
exercise a week can reduce a man's heart attack risk by 22 percent,
a new study suggests.
The Harvard School of Public Health researchers also found that
about 38 percent of that decreased risk was due to the beneficial
effects of exercise on a man's levels of "good" high-density
lipoprotein (HDL) cholesterol.
The findings were published Oct. 4 the journal
Medicine & Science in Sports & Exercise.
The study included 1,239 men in the Health Professionals
Follow-Up Study who provided information on their weekly amount of
exercise. The researchers also analyzed the men's cholesterol
levels, as well as biomarkers of inflammation and insulin
Between 1994 and 2004, 454 of the men suffered a nonfatal heart
attack or died from coronary artery disease. Of these, 412 men were
compared to a control group of 827 men without heart problems.
"As expected, traditional cardiovascular disease risk factors were more common among cases than controls," study author Andrea Chomistek said in a journal news release. "Men who suffered a nonfatal heart attack or died from coronary heart disease had less 'good' cholesterol, more 'bad' [LDL] cholesterol and were more likely to have high blood pressure, high cholesterol and diabetes."
The U.S. National Heart, Lung, and Blood Institute has more
physical activity and your heart.
