MACRO- AND TRACE ELEMENT STATUS DEMONSTRATED BY PEOPLE GOING IN FOR CYCLIC SPORTS

E.M. STEPANOVA SCIENTIFIC RESEARCH CENTER «ARKTIKA» FEB RAS, MAGADAN, RUSSIA

Objective: the study was aimed at studying the body macro- and microelement contents, and revealing specific microelement characteristics in young sportsmen (ski racing, swimming) who were born in the city of Magadan from European newcomers. Materials and methods: residents of Magadan, 8–20 year-old males and females were examined to study element contents in their hair samples with spectrometry methods. Of note that, all the examinees were divided into two groups: those who do ski racing or swimming with different experience levels were taken to a group of sportive subjects, others who engage in no sports activities – to a baseline group of non sportive ones.
Results: as for males: all the examined male subjects showed deficit of Ca, Co, Cu, Mg, P, and Zn through the two groups. Besides, the male skiers and swimmers experienced profound deficit of I, K, Na. As compared to the baseline, the sportsmen of all the examined ages were reliably low in As, Li, and V. Moreover, the sportsmen aged 8–12 and 13–16 were reliably low in Si, and in I; Na, and Si, respectively, while the sportsmen aged 17–21 proved to be reliably low in Cr and I but high in Co, Fe and P. As for females: all the examined subjects demonstrated profound deficit of Ca, Co, Cr, Cu, I, K, Mg and Zn but excess of Fe and Na. The female skiers and swimmers, besides, experienced deficit of Cr, P and Zn. As compared to the baseline, the sports girls of all the examined ages were reliably low in As, Cr, Li, Si, Sn and V. The adolescent girls, moreover, were reliably low in I, Hg and Pb but high in B (aged 12–15) and reliably low in Se (aged 16–20).
Conclusions: found that, element systems of male and female athletes can be considered as of “the North-conditioned type” since the examined males and females showed lowered Ca, Co, Mg, Se, and Ca, Co, K, Mg, P, Se, respectively, in comparison with the normal range. Of note that, of all female subjects, sports girls demonstrated their element systems to have lowered functional reserves. On the contrary, male examinees going in for sports proved to have the most stable element systems. In addition, the following subjects should be given specific attention at active doing sports: 8–12 and 13–16 year-old males and 16–20 year-old females.
