Abstract
The aim of this study is to investigate the effect of 6 weeks of intermittent exercise on the serum level of nitric oxide, insulin resistance and some lipid profiles in male diabetic rats. Materials and methods: In this experimental study, 60 anesthetized rats (200±20) were randomly divided into 6 groups of 10:1-control-healthy, 2-sham, 3-periodic, 4-periodic+saline, 5-diabetic and 6- Diabetes + interval training were divided. Diabetes was induced by intraperitoneal injection of nicotinamide-streptozotocin. The subjects trained on the treadmill for 6 weeks, 5 sessions a week. 48 hours after the last training session, slaughter was performed and then glucose, insulin, nitric oxide, LDL, HDL, TG and cholesterol levels were measured. One-way variance test and Tukey's post hoc test were used for data analysis(p<0.05). Results: Induction of diabetes increased glucose and insulin resistance and decreased insulin and nitric oxide in the diabetic group compared to the control group. After 6 weeks of intermittent training in the diabetes group + intermittent training, the amount of glucose and insulin resistance decreased compared to the diabetes group, but the nitric oxide level increased compared to the diabetes group. But it had no effect on insulin levels. Also, 6 weeks of intermittent training had no significant effect on the amount of lipid factors in different groups(p<0.05). Conclusion: According to the results of the present study, it seems that interval training can create a protective effect against vascular diseases in diabetic patients by reducing insulin resistance and increasing nitric oxide, and as a result, improving vascular function.
