The goal of this final paper was to find out what preschool children do in their free time and whether they engage in any kinesiology activities. For the purposes of the research, a questionnaire was conducted, which examined eighty parents of preschool children. The results of the research show that 65% of the examined children engage in one or more physical activities, while as many as 35% of them do nothing in their free time. Since children under the age of three are also included in the research, this is not so surprising because in most cases children at that age do not attend any organized kinesiological activity. The largest share of the surveyed children spends their free time engaged in dancing (14%), followed by football, swimming and martial arts. Research shows that children of preschool age are usually engaged in kinesiology activities twice a week, while some of them attend activities even more than once a week (3-4 times), with a time period of at least 45 minutes to an hour or more. Parents confirmed that 89% of them believe that the activities are financially profitable, while 11% of parents claim that the activities are too expensive in their city. Likewise, the offer of activities varies from city to city, so half of the respondents are satisfied with the offer, while others say that their city does not have activities suitable for preschool age. The research data show that a large number of passive content has a great impact on children and their physical inactivity (hypokinesia). The largest percentage of parents say that watching TV and using mobile phones prevents them from engaging in physical activities (63%), while a few parents agreed that the problem is also with adults, who are often busy with work and do not manage to spend enough quality time with their children in activities. Although today's parents are divided between various responsibilities, research shows that parents, as far as they are able, in their free time join their children in their activities and take them out to parks, walks or take them riding bikes and strollers.
