Exercise is an important component of diabetes management and plays a positive role in the prevention and treatment of diabetic kidney disease. Exercise reduces the albuminuria and improves renal outcomes in patients with diabetes，which is independent of blood glucose control. Previous studies have shown that exercise can improve renal function by improving glucose homeostasis and endothelial cell function，reducing oxidative stress and inflammation，regulating renin -angiotensin -aldosterone system and biological action of actin. Recommended types of exercise include aerobic exercise，resistance exercise，combination exercise and flexibility exercise. Appropriate exercise methods should be selected according to individual condition in clinical practice.
