RESUMEN
BACKGROUND: Obesity can lead to a number of alterations in biomechanical structures. We aimed to assess the effect of aerobic plus resistance training associated with an interdisciplinary approach on visceral fat and isokinetic parameters in a long-term weight loss therapy program. METHODS: Forty-four postpubertal obese adolescents were involved in the 1-year interdisciplinary weight loss therapy program (clinical, nutritional, psychological and physical training). Body composition, and visceral and subcutaneous fat were measured by DXA absorptiometry and ultrasonography, respectively. Peak torque was analyzed using an isokinetic dynamometer. Statistical analysis was performed using t-tests to assess the effect of the intervention. RESULTS: There was a significant reduction in body fat with an inverse increase in lean mass. Positive correlations were observed between peak torque and lean body mass and negative correlations with visceral fat, gynoid fat mass, arm fat mass and subcutaneous fat. CONCLUSIONS: An interdisciplinary weight loss program can reduce body fat and increase peak torque and improve muscle strength. The results reinforce the importance of this kind of approach to treat obesity and improve the quality of life in this population.
