Abstract
The purpose of the study was to compare physical capacity of swimming children, prior to and after three-weeks administration of vitamin B1 and B2. Fifty-five children (25 boys and 30 girls), aged 12-15 years, were studied. The risk of vitamin B1 and B2 deficiency was evaluated with enzymatic tests. Determinations were made twice: prior to and after administration of the vitamins or placebo. Physical capacity was also evaluated on two occasions with an indirekt VO2max measurement. Results have shown that periodical administration of vitamins to swimming children had no influence on physical capacity improvement, except in case of two children, one of whom demonstrated a moderate risk of vitamin B1 and the other of vitamin B2 deficiency. It seems that under the conditions of proper diet and moderate training load additional doses of vitamin B1 and B2 should not be recommended for children. Verf.-Referat
