Atherosclerosis is a chronic disease whose first stages can begin in childhood. Obesity is one of the major risk factors for atherosclerosis, which is becoming an epidemic. The increase in prevalence of obesity has focused more attention on the relationship between obesity and atherosclerosis, and although the relationship between obesity and atherosclerosis has been widely reported, its potential mechanisms still need to be further elucidated. Salusins are a new class of bioactive peptides that play an important role as endogenous regulators of atherosclerosis process. Obesity is associated with a chronic inflammatory response characterized by abnormal adipokine production and activation of some pro-inflammatory signaling pathways. Past studies have shown that inflammatory process has a cause and effect relationship with obesity and cardiovascular diseases, including atherosclerosis. Also, arterial endothelial disorder is an early disorder in process of atherosclerosis, and presence of this disorder in obese children has been widely reported. The most important potential factor that will lead to obesity, inflammatory conditions and endothelial dysfunction is immobility. On the other hand, physical activity has wide health benefits and is considered as an important factor in primary and secondary prevention of cardiovascular diseases. Therefore, the current research seeks to investigate the role of physical activity in improving endogenous regulators of atherosclerosis in obese and sedentary children.

Aim: Obesity and overweight along with metabolic disorders associated with them is one of the very important concerns in today’s world. According to the fact that chihdren and adolencrs bodies are in asensetive stage of growth and preparation for aduhthood, we aim to review the effects of high intensity interval training over the course of 12 weeks on testosterone, cortisol and lipids profiles levels in obese and overweight. Method: In this study 20 boys were selected based on per- post test in to control and high intensity interval training (HIIT) groups.Anthropometric measures, maximal aerobic speed (MAS), cortisol and testosterone levels, and lipid profile were measured in all subjects before and after training. Training group participated in a training program at 100 to 110% of MAS and 3 times per week during 12 weeks. Independent t-test and Paired t-test with a significance level of (P≤0/05) was used to analysis variables. Results: Following the training program, in training group, anthropometric measures including weight, BMI, percentage body fat and waist-hips ratio and cortisol resting level, TC, TG, LDL-C decreased, and HDL-C increased but no effect on testostron resting levels. In control group, anthropometric measures and TC, TG, LDL-C increased, while HDL-C decreased. Conclusion: Prescribing ideal training course to help obese boys has not been recognized yet But, the finding in this research shows that periodic intence work out has a economic potential, and the efficiency of training Protocol for overweight and obese people, especially children and adolescents.
