The modern way of life brings many changes regarding the development and attitudes of students towards various topics. Today's lifestyle is predominantly sedentary, both for adults and children and adolescents. The development of modern technology and the growing interest of children and young people in digital content (especially social networks) necessarily leads to a decrease in interest in other activities, especially those that require leaving the warmth and safety of our homes and engaging in some kind of physical activity. Play, and therefore movement, in addition to being a main source of entertainment, are also considered the basic needs of every child, by which he/she acquires skills needed for proper further motor development. Motor skills are needed for the development of other competencies necessary for independent living, but nowadays, under the influence of various factors, they are highly neglected. Children basically have a lot of free time after school, which needs to be filled smartly in order for it to positively affect their overall development. The aim of this paper was to describe and explain the kinesiological activity itself, its types and impact on students health. Then physical education and its aspects, extracurricular and extracurricular activities and students' free time, and anthropological and psychological differences between girls and boys (gender dimorphism). As a part of this paper, a research was conducted. The sample consisted of 74 students of younger school age (2nd to 4th grade of elementary school, or 7-11 years). After completing the questionnaires containing questions aimed at revealing students' attitudes towards kinesiological activities in their free time, the results indicate that there is no noticable difference when it comes to attitudes of young boys and girls towards kinesiological activity during their free time. The answers have shown that the respondents have approximately more than 4 hours of free time in a day, and that they luckily still chose to direct that time towards playing outside with their peers, despide all the techonogical devices offered to them.
