The best asset in maintaining health and body shape is physical activity that affects the development of motor abilities and motor skills. From an early age children should be guided to carry out certain forms of physical exercise and to develop awareness about the benefits of sports. Parents and educators have the largest role in it because they spend the most time with children. Some of the benefits of regular physical exercise are: the development of motor skills, improved self-esteem, socialization, developing positive self-image and maintaining healthy body weight. Children in kindergartens can engage in a variety of activities but there are kindergartens, which even in this time, are not aware of the importance of regular physical exercise and do not exercise properly with the children. Positive attitude towards physical exercise can be created in the preschool period so it is important that parents and professionals who exercise with the kids organize and carry out well conceived physical activities. For the purpose of this paper an online research study was conducted to determine the influence of parents' sporting habits, their knowledge and attitudes on physical activity of children from 3 to 6.5 years. The results of the research show that parents have less free time because of work commitments, that they are familiar with the benefits of physical exercise and that they support their children. Most of the children are showing interest for sports and they participate in daily physical activities. The statistic shows that the children of parents involved in sports are more interested in sport themselves. Although parents with different socioeconomic statuses and education levels provided similar responses, it is still important to raise parental awareness about the importance of regular physical exercise.
