Regular physical activity, proper nutrition, and healthy and hygienic habits improve the health and development of anthropological features in children. It is crucial to expand preschool children's attitudes and beliefs towards a healthy lifestyle to lay the foundations for healthy future life. Educators are the first to introduce children to organized physical exercise, so their opinions can influence children's opinions. Advocating positive attitudes towards physical activity can be useful in affecting children's health and development. Therefore, children should be encouraged by positive attitudes towards physical activity in order to keep those attitudes later in life. The primary goal of this research is to determine are there differences in educator's opinions about the importance of conducting physical activity in preschool children considering educator's age, education degree, and personal physical activity. A survey questionnaire was used to assess educator's attitudes. The research was conducted online, on a sample of 600 educators. It participated 594 female and 6 male respondents. The results of the research showed statistically significant differences between younger and older educators regarding their opinions about physical activity benefits. Significant differences are present in dimensions of health benefit, psychological benefit, social benefit, and ecological benefit in which educators younger than 40 have more positive attitudes towards the importance and benefits of physical activity. Further, research shows that there are no statistically significant differences in dimensions of physical activity benefits between educators with degree in professional study and educators with university degree, except in the particle of social benefits. Hence, educators with university degree have less positive attitudes towards the claim that child learns norms of behavior, attitudes, and values through physical activity. Statistically significant differences are present in the dimensions of health benefit, psychological benefit, social benefit, ecological benefit, and economical benefit in which educators who are sufficiently physically active have more positive attitudes towards the importance and benefits of physical activity. Educator's positive attitude towards physical activity benefits is very important for their nurturing and educational work of directing and encouraging children to daily perform different types of physical activities and indirectly influencing maintaining and improving children's health.
