Abstract

Prolonged exercise is an unusual type of physical activity in children, but it is often used and recommended in some training methods for various kinds of sporting activity. However, even now, general opinion is not consistent as to the beneficial or harmful effects of the child’s ability to perform this type of exercise. On the other hand, it has been pointed out that the endurance running time of the adults in the test under review was better than that of the children, but the children were less fatigued after the endurance running race than the adults (Jokl 1963). This problem in children has been almost neglected except by a few authors (Ekelund 1967a; Mácek et al. 1976). The purpose of this study is to elucidate the difference between children and adults in the respiro-circulatory changes during 1 -h exercise and to examine the abilities of children in prolonged exercise.
