The main goal of this thesis was to analyze parental support and influence on children's participation in extracurricular sports activities. For the purposes of analyzing parental support, a survey questionnaire was used, which for the purposes of this paper contained 20 items. The sample consisted of 401 respondents, average chronological age 39.38±5.95 years. On the other hand, there were 197 children from the female population and 204 from the male population, with an average chronological age of 9.06±1.42 years. The questionnaire was answered by two groups of parents: the first group consists of parents of children who never, rarely or sometimes participate in family activities that include physical activity, while the second group consists of parents of children who often or very often participate in family activities that include physical activity. The results showed that children whose parents actively participate in family activities play more and communicate better with their parents. Parents consider summer vacations useful for children's development, especially when it comes to encouraging self-confidence and independence. Statistically significant differences were also found, indicating that parents who regularly engage in activities with their family do not attach such importance to financial aspects, compared to parents who rarely participate in such activities. For parents, the sporting success of their children is not as important as their health well-being and the development of social skills. Lack of time and insufficient information are the main obstacles in providing support for children's sports activities.
