The aim of the present cross-sectional study was to compare the physical fitness between the obese, overweight, and normal weight children. A total of 453 children aged 6-12 years were participated. Children were categorized as "normal weight", "overweight" and "obese" using The International Obesity Task Force (2000 & 2007). Body weight, height, and percent body fat were measured and body mass index (BMI) was calculated. Physical fitness including standing broad jump, sit-ups, shuttle run,

Results revealed that obese children had an inferior performance in all physical fitness tests including the standing broad jump, sit-ups, shuttle run, 50-m sprint and leg strength normalized for body mass (p<0.05), except flexibility (p>0.05) than overweight and normal children. The same pattern was observed between overweight and normal children, significantly (p<0.05). In addition, absolute leg strength and fat-free mass were higher in obese children than in overweight and normal children, respectively (p<0.05). After controlling for fat-free mass, the group differences in leg strength were not found (p>0.05).
