ABSTRACT
Presence of children in sport today is more obvious than ever. World and Olympic champions, especially in some sports (gymnastics, tennis, swimming, ice skating), are younger and younger. This makes the problem of selection in sport even more important. In soccer, boys are involved in specific training programmes also very early. For that reason it is important to establish physiological characteristics of young players and to see whether these characteristics can help in the process of selection. This study is concerned with this problem.
