42 obese adolescents participated in a 10‐week multi‐component exercise, diet, and behavioral modification program (MC) or standard physical education classes (PE). The MC program included a supervised 30‐minute resistance training circuit program 3 d/wk in addition to 1‐d/wk of aerobic training and 1‐d/wk of behavioral modification. The diet was 500 kcals below REE and consisted of 55% C, 15% P, and 30% F. Data were analyzed at 0, 10 and 22 weeks by ANOVA with repeated measures and are presented as means ± SD from baseline. Significant interactions were observed in body mass (PE 2.82±2.7; MC 0.58±2.5 %, p=0.02); fat mass (PE 3.64±5.9; MC −2.66±5.7 %, p=0.006); percent body fat (PE 0.52±4.7; MC −2.92±4.4 %, p=0.024), triglycerides (PE 44.8± 85; MC −9.6±35 %, p=0.002), HOMA‐IR (PE 49.4±70; MC 17.6±67 %, p=0.052), physical activity environmental factors (PE −6.92±18.7; MC 10.0±28 %, p=0.039), fruit and vegetable negative decisions (PE 31.7±50; MC 3.4±47 %, p=0.043), and dietary protein intake (PE −3.3±53; MC 8.2±59 %, p=0.025). Significant time effects were seen in body mass (1.6±3%), fat free mass (2.7±4%), bone mineral content (3.6±5%) and bone mineral density (3.4±3%). Results indicate that the PE and MC programs promoted improvements in health and fitness. However, subjects in the MC program observed significantly greater improvements in body composition, triglycerides, and insulin sensitivity.
