Effect of two training on orexin A and lipid profile in obese adolescent boys
Abstract
Given the uncertainties associated with orexin A and obesity, the present study was conducted to identify the effect of endurance training and HIIT on orexin A and lipid Profile in obese adolescent boys. For this purpose, 35 healthy, inactive and obese boys (aged mean 15.5±0.69 years, BMI percentile equal to or higher than 95% and BMI 28.72±2.20 kg/m2) were divided into three equal groups, control, HIIT and endurance training groups in a semi-experimental, randomized and double-blind design. HIIT and endurance training groups participated high intensity interval and endurance running in eight weeks, three days per week. Orexin A, LDL, HDL, TG, TC Plasma levels and WHR, BF%, BMI and VO2max were measured before and 48 hours after the last session of training. Data as mean ± SD using repeated measure ANOVA was analyzed at α ≤ 0.05. Training was caused significant lower of triglycerides and anthropometric parameters such as body fat percentage, body mass index and waist to hip ratio (P < 0.05). But, significant differences were not observed in orexin A, total cholesterol, LDL and HDL plasma levels, in control and experimental groups (P > 0.05). Therefore, endurance training is more effective than HIIT in improvement of obese adolescent boy’s body composition and HIIT is more effective than endurance training to reduce triglycerides. However, changes that may not be in line with changes occurring in orexin A. Thus, it is recommended to repeat like this study in multitimes training with control of sleep, nutrition, puberty changes.
