The aim of the present study was to analyze differences in motor and cognitive abilities of children depending on their value in quantitative indicators of Body Mass Index (BMI) and subcutaneous fatty tissue. The study sample consisted of overall 910 boys and girls, aged 11 to 14, all from elementary schools in Vojvodina (Serbia). Six anthropometric, eight motor and one cognitive variable were analyzed to identify quantitative and qualitative differences in motor and cognitive functioning of children. Children were divided into three groups within gender based on their body mass index calculated and subcutaneous fatty tissue measured. The results obtained from the study indicate the existence of differences in motor and only partly in intellectual abilities between groups of subjects. The greatest differences between the clusters were found in the level of coordination of the entire body, and the static strength of arms and shoulders.
