The environment in which children are growing up today is significantly different from the past when children used to spend much more time playing outdoors and engaging in various activities. Today's children are exposed to screens, spending more time sitting and not participating in sports activities. It is important to raise awareness of this issue and address it because these habits can lead to problems like obesity, diabetes, and other related diseases. It is important to raise awareness about the role and significance of sports activities for preschool children, and it is necessary to involve them in various forms of such activities. Children who have diabetes should also be included in these activities, but they need to be monitored during participation. At the beginning of the paper, the concept of sports and physical activities is defined, along with their role in child development. Following this, the concept of diabetes as a disease is introduced, as well as sports activities suitable for children with diabetes. By analyzing professional literature on sports activities and their impact on children with diabetes, important and relevant information is highlighted. Finally, the paper concludes with a summary based on this data. This thesis aims to analyze the existing research on the topic of sports activities in preschool children and diabetes, and to determine whether preschool children with diabetes can engage in sports activities.
