The topic and goal of this thesis is to recognize the importance of children's involvement in kinesiological activity from an early age and children's free time. Everyday movement, movement is innate in every human being and it is necessary to encourage, develop and practice kinesiological activity. Children should be encouraged to lead a healthy lifestyle that includes daily kinesiological activities, because it is very important for every parent and educator that children develop properly. As kinesiological activity is most important from an early age due to its rapid growth and development, one of the most important tasks for children is motor development and basic motor skills. From an early age, a child develops basic motor skills: coordination, balance, precision and speed. Also, the child develops and improves the basic forms of movement, starting from crawling, walking, running, pulling, descending, lifting, carrying, grabbing. Today's pace and way of life has changed over time and most children spend their free time in front of the screen. It is very important that the need to engage in kinesiological activities and the need to move from an early age. For children, play is the most effective educational tool that affects all aspects of development and forms and shapes the child's personality, and through it children learn the fastest. As part of the work, I conducted a survey on children's free time and how active they are. Based on the questionnaire, I surveyed which kinesiology activities preschool children engage in and how they spend their free time. The T-test gave me the result that girls and boys of preschool age are equally involved in sports activities and that there are no differences between them in the total time in which they are active.
