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 ( p < 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 ( p > 0.05). Maximal isometric strength and maximal oxygen consumption showed significant increases after the intervention period ( p < 0.05). There were reductions in insulin, HOMA-IR, total cholesterol, triglycerides, and low-density lipoproteins ( p < 0.05), and an interaction within the resistance plus aerobic training group showed lower values for triglycerides when compared to itself ( p = 0.002). No difference was found in fasting glycemia for either group ( p > 0.05). It is worth noting that the equalization training variables presented no differences between the two groups ( p > 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.

Introduction: To investigate the effects of a multiprofessional approach on anthropometric parameters and body composition and the level of food processing in adolescents. Methods: Twelve overweight/obese male adolescents between 13-17 years old participated in a series of 12-week multiprofessional interventioms led by physical education, nutrition and psychology professionals. The participants were assessed before the intervention as well as at 6 and 12 weeks into it. Anthropometric assessments were performed, including body weight, stature and body mass index; body composition, with fat mass (FM), body fat (%BF), skeletal muscle mass (SMM) and resting metabolic rate (RMR) and by filling in a three-day food record, in order to calculate the ingested foods, by the level of processing of the food: fresh, minimally processed, processed and ultra-processed.  Results:  No differences were observed for the anthropometric parameters performed at different stages (p>0.05). Reductions for FM and %BF and increases in SMM and RMR (p<0.05) were identified, all after 12-week of the intervention. There was an increase in the consumption of natural foods/g, and an increase in the caloric consumption of processed foods/kcal, after 12-week of interventions (p<0.05). Conclusion: The model resulted in decreases in FM and %BF, an increase in SMM, RMR, natural foods/g and processed foods/kcal.
