ABSTRACT: The effect of different levels of physical activity on the hair content of macro and trace elements in young women was studied. The study involved 59 clinically healthy female students (18–22 y.o.) studying at the P.G. Demidov Yaroslavl State University (Yaroslavl, Russia). All students were divided into 3 groups: I – high physical activity (at least 4 times a week training in sports clubs); II – medium (visit the fitness groups 2–3 times a week); III – moderate (physical exercise according to university educational plan). It was shown that physical activity changes the content of macro and trace elements in the hair in different directions. Thus, in case of essential trace elements, high physical load is associated with Co, Fe, Mn increase, and Zn decrease. As for toxic and conditionally toxic trace elements, there is an increase of hair Al, Cd, Sb, Sn, with a simultaneous decrease of Hg. Regarding macro elements, there observed an increase of Ca, Mg. And in relation to conditionally essential trace elements – a Ni and V decrease. There was concluded the possible relationship of high physical activity, on the one hand, with an increased intake of various trace elements with food and water and, accordingly, their induction of excretion, and on the other hand, with an increased requirement for some essential and conditionally essential trace elements.
