The aim of this study was to determine the kinematic pattern and define the current standard of motor skills during the execution of throwing and catching a ball with both hands from the ground and from a height in early and preschool-aged children, through the analysis of interindividual biotic variation in the kinematic movement patterns of children in relation to their chronological age, body mass index, and ball-handling experience. The research was conducted in the mixed educational group "Ježići" at the "Slavuj" Kindergarten in Sveta Nedelja. The study involved 18 early and preschool-aged children, 5 boys and 13 girls. The average age of the participants is 42.83 months (min = 24, max = 56). To assess the morphological characteristics of the sample, variables such as body height, weight, and body mass indeks were applied. To evaluate deviations in motor patterns during throwing and catching a ball with both hands, the success rate was assessed, and the duration of the motor patterns for throwing and catching a small and large ball from the ground and from a height was measured. The results of the study indicate that deviations in the motor patterns of early and preschool-aged children when mastering throwing and catching a ball with both hands are most influenced by the child's age and the lack of prior daily experience with handling a ball. This study showed that gender and body mass index do not have a significant impact on deviations in the motor patterns of early and preschool-aged children when mastering throwing and catching a ball with both hands. Motor development, as one of the components of overall development, needs to be stimulated daily through numerous opportunities for movement, both in the family and institutional context. This can only be ensured for the child by aware parents and educators, as learning from the model of a close person is extremely important for a child in the early and preschool period.
