By now, most people have heard of a few-year-old study on the benefits of exercise. We’ve all come across studies that claim that exercise helps the heart in a number of ways, and now, in a new Journal of Obesity study, a team of researchers at Harvard’s School of Public Health has confirmed the efficacy of exercise in cardiac health. The study, published today in the Journal of the American College of Cardiology, is the first to assess the impact of physical activity on cardiovascular health among adults between 65 and 80 years old.
The researchers looked at three groups of a national sample of older adults: the physically active (PA) and inactive (IA) groups, who were divided into two groups based on the amount of exercise they engaged in weekly and the amount of time they devoted to exercising each month. The researchers looked at the effects of different levels of exercise, as recommended by the US Department of Health and Human Services (DHHS). The researchers looked for differences in the risk factors of heart disease such as high cholesterol and diabetes as well as health-related quality of life. This type of research is particularly important in cardiovascular health, since exercise is widely recognized as an important factor that contributes to good health, and it has also been shown to be associated with the prevention of many ailments.
The researchers followed up with people in the IA group, looking at how they and their age cohorts fared over an eight-year period. The researchers found that while the PA group had a decrease in heart disease risk as well as a decrease in the risk of diabetes and high blood pressure, the IA group still suffered from many of the risks associated with being overweight or obese.
“These findings are important for assessing the benefits of physical activity for cardiovascular health, since not only was the IAP group not able to maintain a healthy lifestyle, but they also had a higher risk of cardiovascular disease than people who participated in the PA group,” says senior author Dr. Timothy J. Brown, a professor of medicine and public health at Harvard’s School of Public Health and professor of population health and policy at Harvard Medical School, lead author on the JACCH study. “With the current knowledge, we can increase efforts aimed
