This final paper seeks to define different forms of physical exercise and their importance for the overall development of children. To conduct quality physical exercise with preschool children, it is extremely important that the activities are adapted to their age and developmental abilities and individual characteristics, which requires quality preparation and dedication from the educator. Also, the importance of physical exercise can be correlated with the Anthropometric characteristics of the child because keeping children active has a positive effect on their health. Anthropometric measurements assess the nutritional status of an individual child, and it serves as an alarm if a child shows signs of overweight and obesity, or malnutrition and allows us to respond in a timely manner. As part of the paper, data on the height and weight of children obtained from Anthropometric measurements were collected. Based on these data, the body mass index was calculated and then read from the graphs by centile. The data included a total of 49 children aged 5 to 7 years, of whom 25 were boys and 24 girls. As part of the research, descriptive data statistics were performed and t-test analysis was performed, from which the level of significance was obtained to determine whether there are differences between children who exercise 1x in a week and those who exercise 2-3x in a week. The secondary purpose of this paper is to determine the nutritional status of children based on body mass index, apropos what percentage of children belong to the category of normal weight, malnutrition, overweight or obesity. The conducted research, which examined the differences in Anthropometric characteristics and nutritional status with regard to age and frequency of exercise, did not show any significant differences, which can be attributed to the fact that their growth and development take place similarly.
