With regard to their metabolism and cardiovascular/cardiopulmonary system, they have at their disposal good prerequisites for aerobic endurance training. However, it is a matter of the natural movements involved in playing rather than striving to reach a high level of performance. Sports during the preschool age advances physical development and serves as a form of early prevention of the diseases of civilization.
