Aerobic exercise was found to decrease the risk of diabetes-related kidney disease in some people, revealed study published in the American Journal of Physiology--Renal Physiology and was chosen as an APS selectarticle for December.
Early markers of diabetes-related kidney disease include high levels of protein in the urine and a reduced ability of the kidneys to filter out waste from the bloodstream. Chronic kidney disease can also lead to an imbalance of minerals in the body, particularly in the bones. Altered bone mineral content may contribute to disorders, such as the bone-weakening disease osteoporosis.
Researchers studied two groups of rats--both composed of a combination of lean and obese animals--to explore the effect of exercise on kidney disease risk factors. The "exercise" group was exercised on a treadmill for 45-60 minutes each day, five days a week. The "sedentary" group was trained for 15 minutes twice a week to mimic a human sedentary lifestyle.
"We conclude that the introduction of an exercise program based in [aerobic interval training] is a good strategy to present alterations in kidney structure and urinary parameters caused by obesity and the development of diabetic [kidney disease] in obese Zucker rats," the researchers wrote.
