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 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.

Effects of a multi-professional approach on anthropometric variables and food profile of overweight or obese adolescents / Efeitos de uma abordagem multi-profissional sobre variáveis antropométricas e de perfil alimentar de adolescentes com sobrepeso ou obesidade

INTRODUCTION: Investigating the of overweight or obese adolescents' nutritional quality is substantial to guide healthy eating strategiesOBJECTIVE: To assess the effects of a multi-professional approach on anthropometric parameters, body composition, and the level of food processing in adolescentsMETHODS: Twelve overweight/obese male adolescents between 13-17 years old participated in a series of 12-week multi-professional interventions led by physical education, nutrition, and psychology professionals. The participants were assessed before the intervention as well as at 6 and 12 weeks. Anthropometric assessments were performed, including body weight, stature, and body mass index; body composition, with fat mass (FM), body fat (%BF), skeletal muscle mass, and resting metabolic rate (RMR), and by filling in a three-day food record, to assess the ingested foods by its level of processing: fresh, minimally processed, processed, and ultra-processedRESULTS: No differences were observed in anthropometric parameters performed at different stages (p>0.05). Reductions in FM and %BF and increases in SMM and RMR (p<0.05) were identified after, the 12-week intervention. There was an increase in the consumption of natural foods/g and increased the caloric consumption of processed foods/kcal after 12-week of intervention (p<0.05CONCLUSION: The model resulted in a decrease in fat mass and body fat percentage, an in skeletal muscle mass, resting metabolic rate, natural foods/g, and processed foods/kcal

INTRODUÇÃO: Investigar a qualidade nutricional de adolescentes com sobrepeso ou obesidade é substancial para orientar estratégias de alimentação saudávelOBJETIVO: Avaliar os efeitos de uma abordagem multiprofissional sobre os parâmetros antropométricos, de composição corporal e o nível de processamento de alimentos em adolescentesMÉTODO: Doze adolescentes do sexo masculino com sobrepeso/obesidade, entre 13-17 anos participaram de uma série de intervenções multiprofissionais ao longo de 12 semanas, que foram conduzidas por profissionais de educação física, nutricionistas e psicólogos. Os participantes foram avaliados antes da intervenção, após 6 e após 12 semanas. As avaliações antropométricas foram realizadas, incluindo o peso corporal, a estatura e o índice de massa corporal; para a composição corporal foram incluídas: a massa gorda (MG), percentual de gordura corporal (%G), massa muscular esquelética (MME) e taxa metabólica basal (TMB), bem como o preenchimento do registro alimentar de três dias, para avaliar os alimentos ingeridos, via nível de processamento: in natura, minimamente processado, processado e ultraprocessadoRESULTADOS: Não foram observadas diferenças significativas nos parâmetros antropométricos realizados nas diferentes etapas (p>0,05). Reduções na MG e %G e aumentos na MME e TMB (p<0,05) foram identificados após 12 semanas de intervenção. Houve um aumento do consumo de alimentos in natura/g e aumento do consumo calórico de alimentos industrializados/kcal, após 12 semanas de intervenção (p<0,05CONCLUSÃO: O modelo proposto resultou em uma diminuição da massa gorda e percentual de gordura corporal, aumento da massa muscular esquelética, taxa metabólica basal, consumo de alimentos naturais/g e alimentos processados/kcal
