Background: Adenosine monophosphate-activated kinase (AMPK) is a key regulator of cellular metabolism, and its dysregulation is associated with metabolic diseases such as obesity, inflammation, diabetes, and cancer. Therefore, the purpose of this research is the effect of moderate intensity interval training (MIIT) on the total and phosphorylated content of AMPKα1/2 protein in the skeletal muscle of diabetic rats.
Methods: In this experimental study, 12 two-month-old male Sprague Dawley rats with an average weight of 280±30 grams were selected. Diabetes was induced to rats through intraperitoneal injection of streptozotocin solution (with a dose of 65 mg per kg of body weight). These rats were randomly divided into two groups, diabetic training and diabetic control; The training group performed MIIT for 6 weeks at an intensity equal to 55-75% of maximum speed. Data analysis was done through independent t-test in GraphPad Prism version 10 software. The significance level of the current research is P≤0.05.
Results: Total intracellular content of AMPKα1/2 protein did not show significant changes in the training group compared to the control group in the soleus skeletal muscle (P=0.96). In contrast, the phosphorylated intracellular content (P=0.0001) and the ratio of phosphorylated to total form (P=0.002) of AMPKα1/2 protein showed a significant increase.
Conclusion: MIIT increased the protein content of AMPKα1/2 in soleus muscle tissue of diabetic rats, and this could lead to increased energy production and consumption and improved glucose levels in diabetic subjects.
