Abstract

2Background: A High-fat diet can cause obesity and endanger health. Therefore, the present study aimed to investigate the effect of eight weeks of High-fat diet, continuous moderate-intensity training, and high-intensity intermittent training on the gene expression levels of PLIN2 and ATGL in the twin muscles of male Wistar rats. Materials and Methods: Thirty-two male Wistar rats were divided into four groups (n=8): 1-control group with a standard diet (ND) 2-control group with a High-fat diet (HFD) 3-High-fat diet and continuous aerobic training with Moderate intensity (HFD+MICT) 4-High-fat diet and intermittent aerobic training (HFD+HIIT). For one training group, eight weeks of moderate-intensity continuous aerobic training (MICT), and for the other group, eight weeks of high-intensity intermittent aerobic training (HIIT) were performed on the treadmill. Then, 48 hours after the last training session, the twin muscle tissue was isolated to check the expression of PLIN2 and ATGL genes. Gene expression analysis was done by Real-time PCR technique. One-way analysis of variance (ANOVA) and Tukey's post-hoc test were used to analyze the collected data. Results: After eight weeks of training, the level of PLIN2 gene expression in the two training groups was significantly lower than in the HDF group, and the level of ATGL gene expression was significantly higher in both groups than in the HDF group (P<0. 05). Conclusion: It was shown that two exercises had a modulating effect on the expression of genes that are effective in the process of autophagy and the formation of fat cells.
