Background: The objective of this experimental study was to determine the effect of 6 weeks of high intensity interval training (HIIT) on G6Pase expression in liver tissue, serum insulin and glucose and insulin resistance in obese rats with type 2 diabetic and compared with non-diabetic obese group.
Methods: 28 male Wistar rats aged 10 weeks (220 ± 10 g) were obesed by 6 weeks of high-fat diet (HFD). Then type 2 diabetes induced in 14 rats by intraperitoneal injection of STZ (30 mg/kg). Finally, the studied rats were divided into 4 same groups: 1) control obese, 2) interval obese, 3) control diabetic, 4) interval diabetic. Interval groups participated in an interval exercise program of 5 sessions per week for 6 weeks consists of 10 repetitions of a 40-second run on the treadmill with 2-minute rest (active rest) between repetitions. 48 hours after the lasting session, fasting levels of glucose, serum insulin and G6Pase expression in liver tissue in all 4 groups were measured and compared with 2 way ANOVA.
Results: Compared with diabetic control groups, HIIT in diabetic group resulted in significant decrease fasting glucose (p= 0.001). HIIT also led to an increase in serum insulin (p= 0.006) without change in G6Pase expression (p= 0.102) compared to the diabetic control group.
Conclusion: Improved glucose response to interval training in type 2 diabetic rats may be rooted in increase insulin without changes in hepatic G6Pase expression. Measurement of activity or expression of other liver enzymes is suggested for general conclusion.
