Enhanced fitness and renal function in Type 2 diabetes

Area of Science:

• Nephrology
• Endocrinology
• Sports Medicine

Background:

• Diabetic kidney disease is a major complication of diabetes.
• Mild renal dysfunction is common in people with diabetes.
• The impact of exercise on renal function in this population requires further investigation.

Purpose of the Study:

• To examine the renal effects of a 12-week exercise program in individuals with diabetes and mild renal dysfunction.
• To assess changes in estimated glomerular filtration rate (eGFR) following a supervised exercise intervention.

Main Methods:

• A 12-week supervised exercise program was implemented.
• 128 participants with diabetes and mild renal dysfunction were enrolled.
• Estimated GFR was measured before and after the intervention.

Main Results:

• All cardiometabolic variables improved after 12 weeks of exercise.
• A 3.9% increase in eGFR was observed in the overall study group.
• Participants with baseline chronic kidney disease stages 2 and 3 showed significant improvements in eGFR (6% and 12%, respectively).
• 42% of participants with stage 3 chronic kidney disease improved to stage 2.

Conclusions:

• Short-term exercise enhances renal function, particularly in individuals with moderate baseline chronic kidney disease.
• Renal function is responsive to improvements in physical fitness.
• Enhanced physical fitness should be considered a non-pharmacological approach for managing diabetic kidney disease.
