Abstract: (129 Views)
Background: Diabetes can cause serious cardiovascular complications by disrupting the autophagy pathway. Therefore, this study aimed to investigate the effect of high-intensity interval training (HIIT) on the intracellular levels of autophagy proteins in the left ventricular tissue of rats with type 1 diabetes.
Methods: In this experimental study, 18 2-month-old male Sprague-Dawley rats with an average weight of 300±20 grams were selected. Twelve rats had type 1 diabetes after intraperitoneal injection of STZ (with a dose of 50 mg/kg of body weight) solution. Rats were randomly divided into two groups: diabetic training and diabetic control (each group, six heads). A healthy control group (six heads) was also considered. The training group underwent HIIT four days a week for six weeks. GraphPad Prism version 9.5 software and one-way ANOVA, and Tukey's post hoc tests were used to analyze the data. The significance level was considered P≤0.05.
Results: ULK1 and FIP200 levels showed a significant increase in the left ventricle after 6 weeks of HIIT training compared to the healthy control group and the diabetic control group (P=0.0001).
Conclusion: Considering the increase in ULK1 and FIP200 proteins, it can be concluded that HIIT training can activate the autophagy pathway; Therefore, in prescribing this type of exercise for diabetic subjects, the intensity and duration of the exercise should be considered.
