The balance studies among the high-qualified adult sportsmen during the winter period of practices had shown that of the day of a 30-km cross the contents of iron, copper and manganese in the food ration fell to the lowest level of the physiological standard of people not going into sports due to sufficient physical load the process of microcomponents' secretion through bowels and kidneys was outstripping their replenishment from food. The balance of all three microcomponents was negative. During the following three days after the cross due to disbalanced food ration caused by the content of microcomponents the losses of iron and copper were not compensated. The enrichment of the food rations by the set of components caused the hold-up of iron, copper and manganese in sportsmen bodies. The increased usage of the medical iron resulted in sufficient growth of copper and manganese excretion through alimentary canal.
