We all know that exercise is good for you ? it keeps the heart healthy, works? out the muscles and prepares you to take the stairs at work without fainting? from exhaustion. But does all that activity actually prevent you from getting? sick?
According to a study published online by the Archives of Internal? Medicine, the answer is yes. Researchers say that people who are more fit when they are middle-aged have a lower rate of chronic? diseases, including heart problems, diabetes, stroke, kidney disease, obstructive pulmonary? conditions, lung cancer, colon cancer and Alzheimer?s disease.
Previous studies have shown that people who are more physically fit? have a lower risk of dying early than those who aren?t as in shape, but the? current analysis, led by Dr. Jarrett Berry of the University of Texas? Southwestern Medical Center, is the first to expose a connection with chronic? diseases. Berry and his colleagues compared data on fitness levels of 18,670? healthy men and women in their 40s and 50s to Medicare claims for chronic? disease treatments a couple of decades later, when the participants became? eligible for coverage after age 65. Each of the volunteers performed a treadmill? test, during which the researchers measured the length of time they exercised to? exhaustion as an indicator of their fitness. For every one-unit improvement in? fitness, measured as metabolic equivalents, the volunteers enjoyed a 20% drop in? the incidence of the eight conditions the scientists tracked.
