An MTSU professor’s contribution to the growing body of research into fitness among the overweight is the topic on the next edition of the “MTSU On the Record” radio program.

Dr. Vaughn Barry

Host Gina Logue’s interview with Dr. Vaughn Barry, assistant professor of exercise science, will air from 8 to 8:30 a.m. Sunday, Dec. 22, on WMOT-FM (89.5 and www.wmot.org ).

Barry and his colleagues examined 10 prior studies, dividing participants into three weight categories — normal, overweight and obese. Then the researchers compared the participants’ performance on an endurance test, which in most cases was running on a treadmill.

They found that overweight and obese people who were fit had similar mortality risks as fit people of normal weight.

In other words, a person’s fitness level, not his or her weight, is the key factor in determining one’s risk of dying early.

“We’ve all heard of the ‘obesity epidemic,’” said Barry, “but this could be our ‘low fitness epidemic,’ where we as a society need to engineer physical activity back into our lives.”

Barry said the amount of activity necessary to maintain fitness is not as much as we might think. The federal government recommends only 150 minutes per week, in segments as small as 10 minutes each, for good health.

The entire study, which was published in the journal Progress in Cardiovascular Diseases and at www.sciencedirect.com, is available at http://tinyurl.com/ld7tzyr.
