From the current research results on exercise and diabetes, aerobic exercise and resistance training are good choices for diabetic patients. It is suggested that the best exercise program for patients with type 2 diabetes should be a combination of aerobic exercise and resistance training. The mixed exercise of aerobic exercise and resistance training has a good effect on blood sugar control of patients with type 2 diabetes, especially those with poor blood sugar control. It is best to do muscle exercises such as resistance training twice a week, and the resistance is light or moderate during training. Combining resistance training with aerobic exercise can improve metabolism to a greater extent. Although aerobic exercise can improve other aspects of metabolism, it has no significant effect on long-term control of glucose tolerance and blood sugar. Compared with conventional aerobic exercise, a perfect resistance training program can mobilize more muscle groups to participate in exercise.
