Physical activity refers to muscular work with increased energy expenditure during free time, recreation, and sports, in professional activities, and in daily routine activities. Today, we view a child as a holistic being. Their development is a complex phenomenon through various aspects of development, and as such, it is crucial to understand the child's developmental characteristics and abilities. Kinesiological activity is most important in the early stage of development. It can influence physical development and the establishment of a healthy lifestyle. The aim of this thesis is to gain insight into the factors that influence, or do not influence, low levels of physical activity in preschool children. Parents make decisions regarding their children's involvement in sports activities outside or within the kindergarten program; therefore, their attitudes towards children's physical activity during free time were examined. For the purposes of the research, an anonymous online questionnaire was created, consisting of 12 questions. The study involved 35 parents of preschool children, with 8 (23%) responses relating to male children and the remaining 27 (77%) relating to female children. According to the data collected in the research, 94% of the children were involved in sports activities. Boys mostly choose soccer and some form of sports program, while girls choose rhythmic gymnastics and ballet. The obtained results show that parents are aware of the importance of their children engaging in sports activities and involve them in extracurricular or kindergarten sports activity programs.
