Kinesiological activity is the foundation of a healthy life, especially in the modern age in which people have less and less need for active movement and recreation. Trends in globalization, digitalization and the development of new technologies have greatly enhanced certain aspects of life, such as the acceleration of daily activities, but at the same time have created a negative impact on maintaining physical health and the need for physical activity. This is why there are more and more health disorders in the modern world related to the lack of kinesiological activity and obesity, such as diabetes and cardiovascular diseases. This issue particularly affects children and young people, given the increasing use of entertainment technology instead of sports and recreational activities. It is therefore important to identify key risk factors for the health of children and young people, and to take timely preventive measures, which primarily include the introduction of more frequent kinesiological activity and raising awareness of the importance of sports and recreation. As part of this thesis, kinesiological activity in children will be considered in great detail, giving emphasis to the implications of recreation and sports on the health aspect of school-age children. The paper will focus on the demographic analysis of the cities of Zagreb and Daruvar, in order to identify the current state of the young population, as well as the state of the available infrastructure for sports and recreational activities. The primary goal of the paper is to gain insight into the kinesiological activity of students in Croatia, with an emphasis on the cities of Zagreb and Daruvar, as part of which an empirical research will be conducted. The empirical research will be conducted by collecting data on physical activity of students on selected days, which will determine the frequency and access to kinesiological activity in each of the observed cities. Finally, a comparative analysis will be conducted to identify key differences in the approach to student kinesiology activity in Zagreb and Daruvar.
