[Balance of iron and copper in cadets of military school during physical exercise and next-day rest at different times of the year].

According to examination, with the help of emission spectrum analysis method, of 24 cadets-athletes of different specialization it was determined that during physical exercise in summer and in winter loss of ferrum and copper with excrements exceeded the intake if these microelements with food. The next day rise of impaction of microelements and decrease of excretion. But despite the positive balance of ferrum and copper, spend of these microelements during physical exercise wasn't compensated for the day of rest.

[The specific features of copper and manganese metabolism in the use of iron-containing preparations].

Aim: To comparatively evaluate the efficiency of preventive treatment with various iron preparations on copper, manganese, and iron metabolic features in adult athletes.

Subjects And Methods: Forty adult highly qualified sambo wrestlers were examined and divided into 4 groups of 10 persons in each. Group 1 athletes took iron-containing Sorbifer Durules in combination with ascorbic acid; Group 2 received Ferro Gradumet Vitamin C; Group 3 had Hemofer and ascorbic acid; Group 4 took ascorbic acid tablets.

[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.

[Manganese provision in trained and untrained schoolchildren and students in different seasons].

Examination of trained (43 skiers) and untrained senior schoolchildren (31 senior schoolchildren), low-order students-skiers (n = 110) and untrained (n = 17) students, high-order students-skiers (n = 39) and students not going in for sports (n = 60) established that in schoolchildren and students of both groups, the content of manganese in the blood plasma and corpuscles in the trained and untrained schoolchildren and students largely depended on the pattern of muscle activity rather than a season. In young skiers and high-order athletes, the level of manganese in both blood fractions was much higher almost at all stages of a follow-up, especially in the periods of increased training and race loads than that in the untrained persons of their age. In all the groups of senior schoolchildren and students, the dietary intake of manganese was season-independent and less than the recommended values, in schoolchildren in particular.

[Immunological responsiveness in trained and untrained schoolchildren and students during a school year].

Examination of trained (43 skiers) and untrained senior schoolchildren (31 young males); low-order students-skiers (110 girls) and untrained students (17 girls); high-order students-skiers (n=39) and students not going in for sports (n=60) established that in school children and female students of both groups, the cellular and humoral immunogical changes were mainly seasonal: in spring versus autumn, a considerable reduction in the concentration of immunoglobulins (Ig) G, M, and A and circulating immune complexes (CIC) was attended by a significant B-immunity system increase. In the high-order skiers, the time course of changes in immunological responsiveness depended on both a season and a muscle activity regime. In autumn with the start of intensive training loads, the vast majority of immune defense parameters (9/12) were significantly higher in the trained skiers than in the untrained.
