Background: Diabetes is the most common glandular disease in the world. The aim of this study was to compare the effect of three types of endurance, resistance and combination training on inflammation and insulin resistance in visceral adipose tissue of type 2 diabetic rats. 

Methods: For this purpose, among eight-week-old male Wistar rats, 48 ​​rats were selected and randomly divided into 6 groups (diabetic endurance training, diabetic resistance training, diabetic combination training, healthy combined training, healthy control and diabetic control). The rats became diabetic by injecting 95 mg of nicotinamide and after 15 minutes of STZ injection at the rate of 55 mg/kg body weight. 4 days after injection, rats with serum glucose above 300 mg/dL were considered diabetic. Then, the endurance training group trained for 6 weeks, 3 sessions per week with moderate intensity (50-60% of maximum oxygen consumption). The initial load to start resistance training was 50% of the rat's body weight. Each session added 15% of body weight to the weights. The combined exercise group also performed resistance and endurance exercises in a row. 48 hours after the last session, the rats were anesthetized and visceral adipose tissue was removed to examine the variables. 

Results: The results showed that there was a significant difference between the effect of six weeks of endurance, resistance and combined exercise on inflammation and insulin resistance in the visceral adipose tissue of male diabetic mice. 

Conclusion: The results confirm the effect of three training methods on the mechanisms involved in diabetes.
