Background: Zinc-Alpha 2-Glycoprotein (ZAG) has recently been implicated in the regulation of adipose tissue metabolism due to its negative association with obesity and insulin resistance. The purpose of this study is to investigate the effect of eight weeks HIIT on level of ZAG in plasma and adipose tissue in type 2 diabetic male rats.
Methods: Twenty one male rats were divided into the three groups of sham control (healthy), control (diabetic), and interval training (diabetic with training). The training group received 8 weeks of training sessions each with 5-12 repetitions of high intensity training for 15-30 seconds at the speed of 27-34 meters per second on a treadmill followed by one minute of active rest. Twenty four hours after the training session blood and body fat samples were taken to measure ZAG levels. The data was analyzed using one-way ANOVA and Tukey’s post hock test at the significance level of 0.05 (P<0.05).
Results: There were significant differences between the sham control and the control with respect to ZAG contents in adipose tissue, which was lower in the diabetic control group (P<0.001). Moreover, significant differences in ZAG contents of adipose tissue were also observed between the sham control and the group receiving the training, with the sham control having higher ZAG contents in adipose tissue (P<0.005). The eight-week HIIT significantly increased the amount of secreted ZAG in adipose tissue compared to the control diabetic group (P=0.003). No significant differences were recorded between the groups in ZAG plasma levels.
Conclusion: The HIIT increased ZAG content in the adipose tissue of the male diabetic rats. This can reduce insulin resistance in type 2 diabetes.
