[Hygienic rationale for diagnosis and correction of excessive body weight in schoolchildren with physical training]. / Gigienicheskoe obosnovanie diagnostiki i korrektsii izbytka massy tela u shkolnikov sredstvami fizicheskogo vospitaniia.

The results have shown that schoolchildren with moderate body mass (M +/- 0.3 sigma) have the highest physical capacity for work (PWC 170/kg) and schoolchildren with body mass from M + 0.3 to M + 1 sigma show a decrease by 20% and with an excessive body mass M + 1.75 sigma by more, about 40%. Bearing in mind this rough drop of capacity to work and the significant aggravation of functional state with an excessive body mass M +/- 1 sigma we consider that limitation of body mass standard by limits M +/- 0.67 sigma is advisable. The studies showed the high efficiency of exercises of cyclic nature (swimming, running, skiing, bicycle) with a view to correcting disorders due to obesity.

The research specific to the changes in body functioning under the effect of various loads of cyclic character was carried out. The results thus obtained made it possible to analyze sex- and age-specific characteristics of body functional capacities of schoolchildren aged 6-15 (yearly characteristics). It was pointed out that by 13-14 years the schoolchildren, primarily girls, lost some of their adaptation capacity to physical load. The problem could be solved due to additional physical training activities aimed at the development of endurance, the trait being of primary importance for health promotion in schoolchildren.
