The benefits of sport on overall human development have been determined by analyzing the results of numerous studies conducted across the world and including Croatia. Most of the research was conducted with coaches and parents while a few studies were conducted with children. For example a small number of studies focused on putting the child's perspective and experience as the center of attention. The cognitive goal of these studies was to determine whether the experiences of childhood quality differ with regard to gender, age and sports. Then in accordance with the obtained results to offer guidelines for improving the children's quality of their own childhood and popularization of sports. The questionnaire for the survey was independently developed and contained 18 multiple-choice and/or supplementary questions and 19 statements with which the respondents determined the degree of agreement on the Likert scale of 5 degrees. 127 respondents participated in the research, of which 110 are engaged in sports, and the remaining 17 were not engaged in any sports activities. The analysis of the collected data concluded that children's experiences of childhood quality do not differ according to gender, but differ according to age. Thereby older children are less satisfied and with regard to sports, children who do not play sports are less satisfied, which all hypotheses were confirmed. Given the results obtained, it is desirable to create an environment that supports sports activities and or any other form of physical activity to promote a healthy lifestyle, both physically and mentally. It also aims to educate children and adults (parents, educational professionals and sports professionals) on the benefits of sport.
