BIO SUBSTRATE CHEMISTRY AMOUNTS IN YOUNG MEN UNDER INCREASED PHYSICAL EXERCISES

Aim. This study was performed to comprehensively analyse the chemistry pictures exhibited by athletes with high sportive results living in the city of Magadan and to determine the specific features of amounts of chemicals in various subjective substrates. Materials and methods. The research involved 19-25 year old athletes in the city of Magadan. We used atomic emission and mass spectrometric methods with inductively coupled argon plasma to study twenty-five macro- and micro minerals in subjective hair and whole blood samples to specify most informative substrates for identifying common types of chronic mineral imbalance. Results and discussion. Examined athletes exhibited higher amounts of Ca, Co, Fe, Se, and Zn in their hair samples and higher median concentrations of blood Na and P; they were also excessive in blood Mn, as compared to the subjects of control group with ordinary mode of physical activity whose blood mineral variables showed higher values of K, Mg, Co, Fe, Se, the deficiency of Co, Cu, Zn, and Fe, and excess of Mg and Se. The authors believe that the differences strongly depend on the athletes diet which, according to our previous studies, mainly consists of vegetables and proteins including seafood, as opposed to the carbohydrate food type characteristic of the control group. Conclusion. The elemental picture of athletes of Magadan is characteristic of residents with typical northern type of deficiency in essential minerals expressed in the hair. Interestingly, hair mineral deficits are more frequent in young men who experience no increased exercise. No excessive toxic elements or heavy metals were found in the studied biological substrates. We believe that, for a long-term assessment of the athletes imbalance which is formed under intense physical activity, hair analysis appears to be more reasonable, in contrast to a quick and fairly informative method blood testing for assessing nutrition or possible intoxication.
