Abstract

The aim of this study was to survey insulin resistance, serum adiponectin, serum FGF21 changes as metabolic cardiovascular risk factors following eight weeks of endurance, strength and compound training in sedentary obese children 8-12 Years Old. Sixty obese male children (age: 10.05±1.41 years old and BMI: 32.36±1.77 kg/m2) were randomly divided into four groups as follows: first group, endurance training; second group, resistance training; third group, compound training, fourth group, control. Exercise training performed 4 times per week for 8 weeks. Combined training was including 2 sessions of endurance training and 2 sessions of resistance training, separately. Blood samples were collected at before and after exercise trainings period to assess the variables. Analysis of variance (ANOVA) with repeated measurement and one-way ANOVA to assess variable changes in four groups was used in SPSS software, version 21. Results showed that insulin resistance decreased and serum adiponectin and serum FGF21 increased in training groups to control group (P<0.001). Serum adiponectin had most increased after endurance training protocol in comparison with resistance and combined training protocols (P<0.001). Therefore, three types exercise training that use this research, specially endurance training protocol could be considered as an appropriate and non-medication approaches to prevent and reduce the metabolic cardiovascular risk factors and obesity-related disorders in obese children.
