Abstract
OBJECTIVE
Global prevalence of obesity has continued to rise and poses public health concerns. Current anti-obesity medications are mainly focused on suppressing appetite. Thermogenic fat cells that increase energy expenditure may be a promising alternative target to combat obesity. Our study aims to investigate the effects of aerobic, resistance, and high-intensity interval training on thermogenic gene expression in white adipose tissue in high fat diet induced obese mice.
METHODS
Fifty 6-week-old male C57BL/6 mice were initially divided into control group and high fat diet group for obesity induction. After 8 weeks of obesity induction, obese mice were subdivided into sedentary, aerobic exercise, resistance exercise, and high intensity interval training groups. Trained obese mice were submitted to 8 weeks of exercise.
RESULTS
Our results showed that all three exercises significantly decreased body weight, and improved metabolic profiles including glucose tolerance, total cholesterol, and low-density lipoprotein cholesterol. Moreover, aerobic exercise training increases serum irisin levels and thermogenic gene expressions such as Prdm16, Cidea, and Pgc-1α in epididymal white adipose tissue of obese mice.
CONCLUSION
Our findings suggest that when it comes to the adaption of thermogenic fat cells, the modality of exercise should be taken into consideration. Aerobic exercise may induce a modest increase in the expression levels of certain thermogenic genes in epididymal white adipose tissue.
