Короткий опис (реферат):
We have determined indexes of physical development harmony in youths: cadets, students, pupils and analysed the regularities of annual changes in conditions of the pedagogical process during the first year of study. Based on the obtained data, we conducted a comparative analysis of these indicators in boys from different educational institutions. We detected a dynamic growth of most average parameters, which means that their annual changes were reliably higher than those in the students and pupils. The most frequently a reliable difference in favour of cadets was found for the body mass index, mass-growth index and the corpulence index (Rohrer).
