Physical activity is an important human need. Being active fulfills not only the need for movement of the body but it also positively influences other various segments of human life. Physically active individuals are happier and more self-confident. They are also less prone to seasonal diseases and are generally in a better physical condition. The World Health Organization’s recommendations speak also about the importance of the optimal frequency and duration of physical activity for both adults and children. Although we are conscious of the need for daily physical activity, there is an increasing number of people who do not exercise in any way, mainly due to lack of free time. The consequences are increased obesity and other conditions connected with the lack of bodily movement and poor nutrition. It is especially important for pre-school children to be physically active because physical activity is an activator of faster and better acquisition of knowledge in all developmental areas. Children in that age have a greater need for being active. It is parents’ duty to ensure a safe and supportive environment (parents being the first trusted adults) so that the child could progress and acquire new knowledge. The educators also carry a major role in encouraging and directing children’s physical activity, through their cooperation with the parents in bolstering children’s motor skills, social-emotional and cognitive development by way of carefully devised and planned physical activities according to their age. This paper shows that parents have a positive attitude about physical activity and are informed about its benefits for human health. Research has shown that the positive attitude alone does not influence a child’s physical activity, but the parents’ supportive behaviour. Educating parents about physical activity can influence their attitudes about it and thus encourage the development of regular physical activity habits of parents and children.
