The research was conducted to determine the differences in body coordination between normal and overweight first-grade primary school children. The sample consisted of 30 students of the first grade, ie children aged 7 years±6 months. The children were divided into two groups, according to the body mass index, in the normal-weight children (19) and the overweight children (11). The level of body coordination in children was assessed using two BOT-2 subtests-the Bruininks-Oseretsky test of Motor Proficiency: Bilateral coordination (7 variables) and Balance (9 variables). The tests are used as a standardized measure of the level of motor abilities in children. The obtained data were processed in the statistical program SPSS 19. Non-parametric Man-Whitney U test was used to determine differences in body coordination. After processing the data, it was observed that there are differences in only four variables, so we can conclude that there were no differences in the overall test. For more reliable results and therefore more complete conclusions, it is necessary to perform tests on a larger sample of children.
