The aim of this study was to evaluate the effects of 8 weeks of aerobic training, resistance training (RT), combined training, and nutritional recommendations on lipid profile and body mass index (BMI) in obese and overweight children and adolescents.
This randomized, clinical trial was conducted on 120 children and adolescents (10-19 years of age) with overweight and obesity. Participants were divided into 4 groups, the 3 intervention groups of high-intensity interval training (HIIT), RT, and combined training, and 1 non-exercising control group with healthy eating recommendations. We considered 24 sessions of training during 8 weeks for the intervention groups. The participants' anthropometric indices and lipid profile were assessed before and after the intervention.
There were no significant differences between the groups in terms of anthropometric indices and lipid profiles before the intervention. After the intervention, there was a significant difference between the groups in terms of high-density lipoprotein (HDL) level; the control group (37.70 ± 9.45) and the HIIT group (43.65 ± 9.09) displayed the lowest and highest mean, respectively (P = 0.040). Comparison of physical variables and blood lipid profiles before and after the intervention showed a significant difference in waist circumference (P = 0.030), hip circumference (P ≤ 0.001), and HDL level (P = 0.040) in RT, HIIT, combined, and control groups.
These results demonstrate that the combined training program and HIIT program with nutritional recommendations in overweight and obese children and adolescents were more effective in reducing BMI and hip circumference, respectively.
本研究旨在评估为期8周的有氧训练、抗阻训练（RT）、联合训练以及营养建议对肥胖和超重儿童及青少年血脂谱和体重指数（BMI）的影响。
本随机临床试验针对120名超重和肥胖的儿童及青少年（10 - 19岁）开展。参与者被分为4组，3个干预组分别进行高强度间歇训练（HIIT）、抗阻训练和联合训练，1个非运动对照组接受健康饮食建议。干预组在8周内进行24次训练课程。在干预前后评估参与者的人体测量指标和血脂谱。
干预前，各组在人体测量指标和血脂谱方面无显著差异。干预后，各组在高密度脂蛋白（HDL）水平上存在显著差异；对照组（37.70 ± 9.45）和HIIT组（43.65 ± 9.09）的均值分别为最低和最高（P = 0.040）。干预前后身体变量和血脂谱的比较显示，RT组、HIIT组、联合训练组和对照组在腰围（P = 0.030）、臀围（P ≤ 0.001）和HDL水平（P = 0.040）方面存在显著差异。
这些结果表明，联合训练方案以及有营养建议的HIIT方案分别在降低超重和肥胖儿童及青少年的BMI和臀围方面更有效。
