The aim of this research is to determine deviations in the motor patterns of children when overcoming resistance. The aim is to analyze intra-individual biotic variations in kinematic patterns of movement, i.e. to determine the current state of the practical model of the structure of overcoming children's resistance and possible deviations from the existing theoretical model. In the research participated 10 children with an average age of 40 months who are part of a mixed nursery group at Dječji vrtić Rijeka. Morphological characteristics of children (weight, height, body mass index (BMI)) were analyzed in combination with the results of motor tasks. The motor tasks that were set were carrying the box along specific paths while collecting the sports props (quads), and the biotic motor skills that were observed were lifting and lowering the box and lifting the sports props. The second motor task was pushing the sponge along the given lines while collecting sports props, and the biotic motor knowledge that was observed was pushing the sponge. For all mentioned motor skills, the time needed to perform was measured. The data were obtained with the help of the Kinovea application and alyzed in the Statistica 14.0.1.25 program. The obtained results indicate the existence of distinct inter-individual differences in morphological characteristics and motor patterns in children, which means that all test subjects' results deviate from the average values of the group. Based on the body mass index (BMI), it was determined that two respondents fall into the category of undernourished, while one respondent is in the category of overnourished. Furthermore, children with a higher BMI needed more time to carry the box, but a higher level of correctness was recorded when picking up and putting down objects. It was found that older children need more time to lift the object and that they use their hands more when pushing the sponge. No statistically significant differences were found between boys and girls. This research wanted to point out potential deviations in children's motor patterns when overcoming resistance, but also general deviations in biotic-motor knowledge, which are more and more common due to a sedentary lifestyle, reduced physical activity and preoccupation with screens. In order for deviations in children's motor patterns to decrease, it is necessary to intervene in educational institutions to include movement in as many activities as possible and in this way to create a learning environment in which the overall growth and development of the child is possible.
