The main objective of this study was to investigate the effects of the order of physical exercises on body composition, physical fitness, and cardiometabolic risk in adolescents participating in an interdisciplinary program focusing on the treatment of obesity. The final 12-week analyses involved 33 female adolescents who were split into two groups of concurrent training (CT): resistance plus aerobic training and aerobic plus resistance training, with equalization performed in all physical exercises. The only difference between the two groups was the order in which the exercises were performed. The results showed reductions in fat mass, body fat, and waist circumference, as well as increases in musculoskeletal mass and resting metabolic rate ( < 0.05) following the multiprofessional intervention period. However, no significant differences were observed in regard to body mass, body mass index, neck circumference, or arm circumference ( > 0.05). Maximal isometric strength and maximal oxygen consumption showed significant increases after the intervention period ( < 0.05). There were reductions in insulin, HOMA-IR, total cholesterol, triglycerides, and low-density lipoproteins ( < 0.05), and an interaction within the resistance plus aerobic training group showed lower values for triglycerides when compared to itself ( = 0.002). No difference was found in fasting glycemia for either group ( > 0.05). It is worth noting that the equalization training variables presented no differences between the two groups ( > 0.05). Based on these results, both CT methods were found to be effective in promoting health parameters in overweight and obese female adolescents, and triglyceride values decreased more in the resistance plus aerobic group. Future studies with larger samples and feeding control should be conducted to confirm or refute our findings.
本研究的主要目的是调查体育锻炼顺序对参与以肥胖治疗为重点的跨学科项目的青少年身体成分、体能和心血管代谢风险的影响。最终的12周分析涉及33名女性青少年，她们被分为两组进行同时训练（CT）：阻力训练加有氧运动训练和有氧运动加阻力训练，所有体育锻炼均进行了均衡处理。两组之间唯一的差异是锻炼的执行顺序。结果显示，在多专业干预期后，脂肪量、体脂和腰围减少，肌肉骨骼量和静息代谢率增加（P<0.05）。然而，在体重、体重指数、颈围或臂围方面未观察到显著差异（P>0.05）。干预期后，最大等长肌力和最大耗氧量显著增加（P<0.05）。胰岛素、HOMA-IR、总胆固醇、甘油三酯和低密度脂蛋白水平降低（P<0.05），与有氧运动加阻力训练组自身相比，阻力训练加有氧运动训练组的甘油三酯值较低（P=0.002）。两组的空腹血糖均无差异（P>0.05）。值得注意的是，两组在均衡训练变量方面没有差异（P>0.05）。基于这些结果，两种CT方法在促进超重和肥胖女性青少年的健康参数方面均有效，且阻力训练加有氧运动组的甘油三酯值下降更多。未来应进行更大样本量和饮食控制的研究以证实或反驳我们的发现。
