The hair content of chromium was decreased in hockey players compare to control, which can reflect the long-term status of glucose metabolism (Table 2). Small wonder that hockey players, for whom endurance is critical, had the increased, compare to control and fencing groups, levels of saliva and hair magnesium, required for normal muscular function, especially the heart. This can explain why the mineral concentrations of fencers looked more similar to ones of the control group. Fencing is more specific to the development of very precise technical skills whereas field hockey includes very strong endurance component. Fencing and field hockey belong to two different sport types.

Nevertheless, sport specific features of mineral distribution were identified in both athletic groups. To account for the effect of the acid, acidic blank solution was added. The blank solution results were taken into account in the analysis of the samples. To calibrate the instruments, multi-element standard solutions were (PerkinElmer). The «Optima 2000 DV» (PerkinElmer) was used as an optical emission spectrometer with inductively coupled plasma. The resulting solutions were analyzed by a quadrupole mass spectrometer with inductively coupled plasma («Elan-9000», PerkinElmer). Thus, the ICP-MS method was used for quantification of Se, Cr and Zn and the ICP-OES one for Mg, ?, ?, Fe quantification, respectively. , et al.: inductively-coupled plasma mass spectrometry (ICP-MS) was used for the quantification of elements having very low concentration range in samples whereas inductively coupled plasma optical emission spectrometry (ICP-OES) was used for quantification of more ubiquitous elements (Harrington., et al. The methods selection was based on the approach described previously by Harrington. Mineral concentrations were assessed using the inductively coupled plasma methods that have recently been validated for its applicability to the analysis of young people exposure to minerals (Harrington., et al. The data on the groups are summarized in Table 1. The girls from the fencing group were significantly (p < 0, 05) taller and heavier compare to other groups. A control group included 28 age- and sex-matched teenagers with reported sport activity less than four hours per week. The samples from young athletes were divided according to the specific sport types: field hockey and fencing. All individuals were reported as healthy without any psychiatric, medical disorders or developmental delay. The participants were 95 children, aged from 12 to 17 years residing in the city of Kazan, Russia.
