[Normalization of the immunologic reactivity of student skiers with a protein preparation].

The effect of the serum-protein concentrate sbk-uf (TY 49626-79) npo "uglich", containing increased amounts of all essential amino acids, on the immunological responsiveness was studied in 21 skier-students. The investigation was conducted during a contest at the beginning and the end of a weekly microcycle when the athlets received the concentrate. Cellular and humoral immunity parameters were studied. It was found that sBK-ooF produced a normalizing effect on the immune processes in the athlets'body, and could be recommended as a biostimulator in the period of hard physical exercises in sports requiring powers of endurance.
