The aim of this study was to identify differences in physical activity before and during the COVID-19 pandemic and to identify which kinesiological activities children of early and preschool age engaged in. For the purposes of the research, the method of an online questionnaire was used to collect the research results. The questionnaire consisted of 25 questions using closed-ended questions, the Likert scale for examining attitudes and frequencies. The sample were the parents of children of early and preschool age who attend preschool institutions in the city of Zagreb, 100 respondents participated in this study. The results of the research show parental awareness of physical activity, where they highlight the main factors that affect it: family, preschool, and the local community. Children engage in kinesiological activities mostly in their free time or as part of a preschool institution, attending sports programs and extracurricular activities such as sports and dance. The most common sports for children are: dancing, gymnastics, football, swimming and martial arts. Before the pandemic, children and parents went to parks and playgrounds, went for walks and danced to maintain the level of physical activity during their free time. The analysis of the research shows that the COVID-19 pandemic did not significantly affect the physical activity of children; i.e. changes in physical activity and motivation to engage in it remained unchanged. Parents were able to maintain a level of physical activity despite the pandemic and conservation measures that limited movement and the availability of kinesiology facilities.
