The main objective of this study is evaluation of the motor biotic knowledge of overcoming the resistance of children aged four to seven years by constructing polygons and determine the anthropological characteristics and motor skills of children involved in the experiment. We conducted the study on a sample of 110 children (59 boys and 51 girls) aged four to seven years. We performed seven tests and two measurements to all repondents, two of which are related to morphological characteristics, six to motor skills, and one test is designed to assess biotic motor knowledge of overcoming the resistance. Based on the obtained results, we can conclude that there is no significant difference between motor achievements (resistance polygon) and anthropological features conducted in the study between boys and girls. There are also no differences in motor achievements (resistance training polygon) and anthropological characteristics between the children who are participating in the sport program compared to the children who are not included in the additional exercise program, because there were no significant differences in the measurements. However, we found that there is a significant difference in motor achievements (resistance training polygon) and anthropological characteristics of children with respect to their age. According to the obtained results, we can conclude that, in respect to motor achievements and anthropological characteristics in the presented sample, there are no significant differences in terms of gender and involvement in the sports program, but they are dominantly influenced by the chronological age of the child, which corresponds with the level of their acquired motor skills.
