Effect of Eight Weeks of Intense Interval Training and Self-Obesity on Serum Lipid Peroxidation Status and Adiponectin Gene Expression in Obese Male Wistar Rats

Abstract

Introduction: A high-fat diet and increased calorie intake increase the prevalence of obesity،,which itself causes many diseases. The studies carried out in the field of investigating the mechanisms related to obesity and its related diseases have introduced the increase of fat mass and as a result the disruption of cytokines as one of the most important influencing factors. Therefore, the aim of the current research was the effect of eight weeks of intense interval training on serum lipid peroxidation indices and adiponectin gene expression in obese mice. Methods: The current research was experimental with a control group. 24 male rats were randomly divided into three control groups, self-obesity group and self-obesity group with high intensity interval training (HIIT). The normal distribution of the data was evaluated using the Shapiro-Wilk test. Then، in order to compare data between groups، one-way analysis of variance was used, and if it became significant، the data were compared using Tukey's post hoc test at a significance level of P < 0.05. Results: The findings of this research showed that in the exercise group, there was a significant increase in the state of superoxide dismutase (SOD) compared to the self-obesity group. However,, there was no significant change in the level of malondialdehyde (MDA) and the level of adiponectin gene expression in the liver of self-obesity group and interval training group. Conclusion: Obesity causes an imbalance in the oxidative status and a disturbance in the production and secretion of adiponectin in the liver tissue of obese mice، and intense intermittent exercise improves the oxidative status, but it does not have a significant effect on the expression of the adiponectin gene.
