Exercise could reduce diabetes-related kidney disease
Aerobic exercise may reduce the risk of diabetes-related kidney disease, according to researchers.
Renal disease is a common complication associated with type 2 diabetes, especially in people who are obese and do not exercise regularly.
The research team wanted to investigate the effect of exercise on kidney disease risk factors. The trial involved lean and obese rats. There were two groups of animals, where one group took part in 45 to 60 minutes of exercise on a daily basis for five days a week. The sedentary group was trained for 15 minutes twice a week to mimic a human sedentary lifestyle.
The most significant finding the researchers saw was an improvement in blood vessel health and overall kidney function. All of the obese rats, regardless of group, had hardening or scarring of the renal arteries, increased protein in the urine, and fat deposits within the filtering structures of the kidneys.
However, the obese rats in the exercise group showed a reduction in these factors when compared to the sedentary obese rats. The exercised obese rats also had changes in bone composition, higher levels of calcium and copper, but lower concentrations of iron, when compared to the lean rats. These changes were not enough, however, to affect the risk of developing osteoporosis.
The researcher said: “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.”
