[Copper content in the organisms of trained and non-trained high school and students in different seasons].

Senior pupils (boys) and students (boys and girls) who go in for sports (skies), were tested to define the copper content on plasma and erythrocytes blood. At was determined, that the content of copper in blood depends mostly on season, but not on physical activity. The maximum content was detected in autumn and spring and minimal--winter and summer. At that, the copper content in male schoolchildren and students was lower than in female students. The concentration of copper in erythrocytes depended mainly not season, but on physical activity. Under intensive training the content of alimentary copper in schoolchildren and students, who go in far sports, was higher in autumn and winter than in summer and more than in non-sportsmen. The copper content in rations of schoolchildren and students was considerably lower the norm in summer and especially in winter
