Introduction: Sports schools play crucial role in promotion of physical activity by organized sports participation. Aim of the study: The aim of this study was to evaluate physical development and nutrition status in children beginning education in sports primary school (athletic profile). Material and methods: The research was carried out in the group of 41 children beginning education in sports elementary school and in group of 46 children beginning education in common primary school. The anthropometric measurements (height, weight) with body mass index (BMI) and skinfolds measurements were performed in the examined groups. Results: No significant differences between groups occurred for basic anthropometric measurements (height, weight, BMI). Extreme values some of these parameters were more common in children from sports school, e.g. tall stature (height above the 95^th centile) and obesity (BMI above the 95^th centile). Underweight (weight below the 5^th centile), short stature (height below the 5^th centile) and malnutrition (BMI below the 5^th centile) were observed only in children from sports school. Thickness of skinfolds (subscapular, suprailiac, crural) were statistically lower in children from sports school. Conclusions: Basic anthropometric measurements (height, weight, BMI) were not significantly different between groups, but extreme values of these parameters were more common in children from sports school. Thickness of subscapular, suprailiac and crural skinfolds were statistically lower in children from sports school.
