If you’re over 30, how are you doing with that regular exercise? According to a new study, people who are fit in their 30s through 50s are more likely to avoid chronic illness later in life

Last week CBS News reported on research done at the University of Texas Southwestern Medical Center in Dallas,

It found that people who were physically fit in mid life may have a lower risk of getting lung cancer, colon cancer, heart problems, obstructive pulmonary conditions, stroke, kidney disease, diabetes and Alzheimer's.

According to the Centers for Disease Control and Prevention, adults between 18 and 65 should get at least two and a half hours of moderate-intensity aerobic activity every week, or one hour and 15 minutes of vigorous -intensity aerobic activity per week.  Also, adults should partake in muscle-strengthening activities at least twice a week.

In the new study, which was published in Archives of Internal Medicine, researchers found that people who increased their fitness levels by 20 percent in their midlife years decreased their chance of developing chronic illness by 20 percent in their later years.  

Fitter people were also more likely to live their final years with fewer chronic diseases. The results were similar in both men and women.

The researchers were careful to point out that genetics play a significant role in health and longevity, so increased exercise may not lead to better fitness in all cases. 

Even so, those of us who are over 30 would be wise to follow the guidelines for aerobic activity and strength training.
