[Effects of prophylactic vitamin administration of physical fitness of schoolchildren in the Arctic Regions].

The effectiveness of prophylactic vitamin administration to schoolchildren in the Arctic region was evaluated in the biochemical investigation of schoolchildren by the assay of vitamins C, A, E, B1, B2, B6, B12 and folic acid in their blood serum before and after "Undevitum" intake. Deficiency of a number of vitamins was detected. It was shown that regular consumption of multivitamin "Undevitum" produced a positive effect on the parameters of their physical activity, the highest effect was observed in children with the normotensive reaction to loading, and it was less expressed in those with pathological hemodynamic reactions to the loading.
