Abstract des Autors

The students of the University of Physical Education differ from undergraduates of other universities, as well as from larger groups of applicants for admission, in body measures and body composition (they are taller and their relative body fat content is less). The body height of students increased during the training period: there were real differences between the starting and the final values. In the group of women, neither body mass or body fat content underwent characteristic changes. In contrast, in the groups of men the body mass also increased; however, only a minimal proportion of the mean differences was accounted for by the body height increase and the change in depot fat quantity. The bulk of body mass increase was attributable to the increase in muscle mass. It can be stated that no appreciable changes occur in the constitution beyond the age of 18-19 years, i.e. regular physical exercise does not change the constitution. Verf.-Referat
