One of the basic tasks of kinesiology is to motivate a person to engage in physical activity on a daily basis, to consume a quality diet and to form healthy life habits. In the preschool age of children, the preschool teachers and parents who spend the most time with children have the greatest influence on their activity and eating habits. Therefore, this research sought to examine parents how much and how their children spend time in activities, during free time, in play. Most parents reported that their child spends time actively, but a smaller number of children attend organized sports activities. Furthermore, it was researched how often children consume different types of foods to gain insight into the diversity of preschool children’s diets. Most of the children of the surveyed parents from the survey have a proper and varied diet, and they consume "fast food" very rarely or not at all. Improper nutrition in the stages of intensive development and growth can cause most of the chronic diseases of children that mark the modern age. Some of the most common diseases we encounter are an obese child or a lean child. In order to ensure proper nutrition in kindergartens, a HACCP system has been introduced that ensures the quality of nutrition in kindergartens. Only proper nutrition and sufficient physical activity help to adopt a healthy lifestyle and positive attitudes about maintaining personal health and community health. Quality spending of children's free time is a phenomenon that is researched every day, and it should be well organized because children have a lot of free time. Parents should provide children with the opportunity to engage in various kinesiological activities already in preschool age, give them a choice of content that the child will enjoy and that will fill his free time.
