The aim of this thesis was to define the concept of free time, point out the importance of physical activity as a way of life, and to find out by research in what way and how often do preschool children spend their free time physically active. For the purpose of the research, an online questionnaire method was used in which a total of 197 respondents participated. The results of the research showed that 97% of children spend their free time in active play, and play is one of the most natural ways preschoolers spend most of their time. Play as an activity should not be neglected as it is good for the child’s physical and mental development. According to the results of this study, it can be concluded that physical activity in most children is appropriate. Most children engage in physical activity recreationally, as indicated by the fact that 47,4% of children do not engage in any organized sports activity that includes a sports club or any organization, but 84,9% of parents believe that their child spends their free time well. Most children spend about 2- 3 hours in active play during their day, which is also considered as adequate physical activity in early and preschool age. 39% of children spend about 1-2 hours a day in active play, and 34% of them spend more than 3 hours a day in active play. Most children spend about 60 minutes a day in front of a screen using some form of multimedia, and only 5% of children do not spend any time in front of a screen. The fact that 97,9% of parents encourage their children to engage in physical activity in their free time is very positive nowadays when neither parents nor children have time to spend their free time better due to obligations.
