ABSTRACT
The aim of this study was to investigate whether the effects of a multidisciplinary intervention on cardiorespiratory fitness are maintained after 6-month follow-up in adolescents with obesity. One-hundred and seven adolescents with obe-sity were intentionally allocated in two groups experimental or control. Adolescents in experimental group underwent a multidisciplinary intervention (supervised aerobic exercise, psychological, nutritional, and clinical counseling). Cardiorespiratory fitness (direct gas analysis), body composition (dual-energy-DXA), anthropometry and blood lipids were measured before intervention (baseline), at the end of the 24-week intervention (post-intervention) and six months after the end of the intervention (follow-up). Cardiorespiratory fitness reduced in control group with no changes in experimental group, and these differences were maintained in the follow-up assessment (control group 24.2±4.4 ml.kg-1.min-1to 22.6±4.9 ml.kg-1.min-1; follow-up 22.6±4.9 ml.kg-1.min-1 vs. experimental group 28.0±4.0 ml.kg-1.min-1 to 29.7±4.0 ml.kg-1.min-1; follow-up 28.9±5.7 ml.kg-1.min-1). Reductions in z-score body mass index (BMI) and increases HDL-C af-ter multidisciplinary intervention were maintained after a 6-month follow-up. In conclusion, the benefits of a multidisciplinary intervention on cardiorespiratory fitness, BMI and blood lipids are maintained after a 6-month follow-up. These findings indicate that multidisciplinary interventions produce long-term health consequences on cardiorespiratory fitness. Reinforcing the importance of lifestyle changes as a therapeutic approach for the treatment of obesity in adolescents.
RESUMO
O objetivo do presente estudo foi investigar se os efeitos da intervenção multidisciplinar sobre a aptidão cardiorrespiratória são mantidos após um período de segmento de 6 meses em adolescentes com obesidade. Cento e sete adolescentes com obesidade foram intencionalmente alocados em dois grupos experimental e controle. Os adolescentes do grupo experimental foram submetidos a intervenção multidisciplinar composta por acompanhamento psicológico, nutricional, clínico e treinamento aeróbio. Aptidão cardiorrespiratória (análise de gases), composição corporal (DEXA), antropometria e perfil lipídico foram avaliados no momento basal, após 24 semanas de intervenção e 6 meses após (follow up). A aptidão cardiorrespiratória reduziu no grupo controle sem alterações no grupo experimental, mesmo após o período de 6 meses (controle 24,2±4,4 ml.kg-1.min-1 para 22,6±4,9 ml.kg-1.min-1; follow-up 22,6±4,9 ml.kg-1.min-1 vs. grupo experimental 28,0±4,0 ml.kg-1.min-1 para 29.7±4.0 ml.kg-1.min-1; follow-up 28,9±5,7 ml.kg-1.min-1). Redução no escore-z do índice de massa corporal (Z-IMC) e elevação do HDL-c verificadas após 24 semanas, foram mantidas após o período de segmento. Os resultados indicam que os efeitos da intervenção multidisciplinar são mantidos após 6 meses de seguimento. Estes achados sugerem que intervenções multidisciplinares podem produzir alterações benéficas de longo prazo na capacidade cardiorrespiratória.
