title: [Zinc and silicon metabolism in highly trained athletes during heavy exercise].
abstract: Trained male athletes were under study. It was found that under the effect of physical stress during the contest in ski race (30 and 50 km) the increase of the zink and silicon levels in the blood plasma correlated with their decrease in the blood cells. A positive zink and silicon equilibrium was observed in the athletes on the day of rest before the contest. Excretion of zinc and especially of silicon through the kidneys and intestine drastically grew on the day of the contest. On the day of rest following the high muscular stress the loss of trace elements appreciably lowered, however, it was higher than that before the contest. The authors recommend the following doses of the trace elements for highly trained athletes: zink--20-25 mg/day, silicon--30-35 mg/day.
