Abstract

This paper deals with the studying of the levels of mineral elements (calcium, magnesium, iron) at elite swimmers (boys and girls) before and after physical effort on the bicycle. 

As a result of our research it was found out that the level of calcium and magnesium is decreased before the physical effort at the majority of the swimmers tested, while the level of iron is at a normal degree. 

The results obtained after physical effort on bicycle denotes of a further decrease of the level of calcium and magne-sium and the increase of iron level in the blood of the tested sportsmen.
