Background & aim: The prevalence of obesity and the socio-economic consequences of it are effective in increasing mortality and cardiovascular disease. The aim of this study was to determine the effect of an aerobic exercise on the amount of epicedial adipose tissue, insulin resistance and some liver enzymes in the fattened vestibular rats with a high-fat diet.
Methods: In the present experimental study conducted in 2018 in Yasuj, 32 Vistar male rats with a mean weight of 200-180 g and 6 weeks of age were randomly divided into 4 equal groups, including: normal nutrition, fattening with a high-fat diet, and then normal nutrition. Obesity with high-fat diet and aerobic exercise and normal nutrition after obesity were divided with high-fat diet. Sampling was performed in the obese group with a high-fat diet after obesity and in other groups 48 hours after eight weeks of aerobic exercise (four sessions per week with 60% of maximum training capacity). Lee index, relative amounts of epicardial adipose tissue, insulin, insulin resistance, fasting blood sugar, pericardial lipoprotein, low-density lipoprotein, total cholesterol and triglycerides, total lymphocytic acid differentiation, and differential enzymaphenazine aminophenazine alphanazinase and liver aspartate aspartate aminotropin. The data collected were analyzed using statistical tests of one-way analysis of variance and Tukey's follow-up test.
Results: The results indicated that a high-fat diet significantly increased the Lee index, relative amounts of epicardial adipose tissue, fasting blood sugar, insulin resistance, blood lipid profile and liver enzymes aspartate aminotransferase reduction and allanine amino acids. The significance of flagella lipoprotein was normal compared to the feed group (P ≥ 0.001). Eight weeks of aerobic exercise also significantly improved the values of Lee index (18.34%), relative values of epicedial adipose tissue (76.9%), insulin (4.01%), insulin resistance (37.48%). Fasting blood sugar (32.38%), high-density lipoprotein (23.65%), low-density lipoprotein (41.37%), cholesterol (24.68%) and total triglycerides (49.55%) as well as liver enzymes Aspartate amino transferees (45.9%), alanine amino transferase (44.34%) and alkaline phosphatase (11.5%) were based on values (P≥ 0.001).
Conclusion: Aerobic exercise reduced the amount of epicedial adipose tissue, body fat mass index, insulin resistance, fatty liver index and cardiovascular risk factors for obesity. Therefore, aerobic exercise can be considered as one of the ways to change the hepatic metabolism and the health of the cardiovascular system in the treatment of related metabolic and cardiovascular diseases caused by immobility and obesity.
