PATINO VILLADA, Fredy Alonso et al. Effect of an intervention with physical exercise and nutritional guidance on the components of the metabolic syndrome among young people with overweight. Iatreia [online]. 2013, vol.26, n.1, pp.34-43. ISSN 0121-0793.

Introduction: Interventions with physical exercise and nutritional guidance show changes in overweight among young people suffering from the metabolic syndrome (MS); nevertheless, their characteristics and results vary. Objective: To assess the effect of an intervention with physical exercise and nutritional guidance on components of the MS among overweighted young people. Materials and methods: Longitudinal study with an assessment before and another after the intervention in nine young people aged 11 to 17 years. Anthropometric aspects, resting heart rate, peak oxygen consumption (VO_2peak), insulinemia, HOMA, and components of the MS were assessed. Intervention consisted of 12 weeks of supervised exercise, three 90-minute sessions/week (aerobic and strength), plus two unsupervised sessions; the weekly supply of fruits and vegetables in order to cover the five recommended daily servings, and individual and group nutrition education. Results: With the intervention waist circumference decreased from 90.5 ± 11.0 to 88.1 ± 9.9 cm; BMI from 30.2 ± 5.8 to 29.3 ± 5.6 kg/m²; total body fat from 39.8 ± 13.0 to 34.3 ± 9.0%; glycemia from 86.0 ± 8.6 to 83.1 ± 5.0 mg/dL; insulinemia from 23.2 ± 9.8 to 19.4 ± 7.6 µU/mL; HOMA-IR from 2.89 ± 1.21 to 2.39 ± 0.93; resting heart rate from 87.9 ± 4.3 to 78.2 ± 5.5 rpm, and VO_2peak increased from 36.3 ± 5.1 to 38.5 ± 4.1 mL/kg/min. Four out of six young people with the diagnosis of MS at the beginning of the study did not present it at the end. Conclusions: Participating in an exercise program and increase in the consumption of fruits and vegetables among overweighted young people with components of the MS produced positive modifications in body composition, VO_2peak, resting heart rate, and glycemia, as well as in the components and prevalence of the MS.
