For the future generations of adults, then we can expect an increase in the benefits of physical fitness of the population, in a more responsible approach to their own health and the preference of a healthy lifestyle. The aim of the research is to determine the relationship between BMI and physical activity levels in children of school age.

We confirmed significant relationship between the level of physical aktivity in the leisture time after school lessons and BMI of children (p <0.04). In boys were found statistically significant differences in physical activity at school (p <0.05) between the monitored categories of BMI. It is necessary to study habits and behavior of children in their lifestyle and look for possibilities that supports positive behavioral of interventions habits of in context of their health.
