ABSTRACT. The relationship between gender and content of macro elements (Ca, K, Mg, Na, P) in blood serum and hair of individuals with different levels of physical activity was studied. It was shown that gender is more important for the hair content of the studied macro elements in comparison with physical activity level. Such dependence was not found for blood serum. A directly proportional dependence of serum Ca (kwp = 0,037), Mg (kwp = 0,048) content from physical activity level was revealed. A two-factor analysis of the effect of gender and physical activity level on serum Ca content showed a statistically significant impact (p = 0.060) only for gender. A larger percentage of explained variance for the specified dispersion model in the case of hair suggests a lower predictive value of serum in relation to changes of Ca level when the studied factors (gender and physical activity level) are combined. In all tested models for different macro elements, the influence of the term reflecting the interaction of factors was insignificant, which demonstrates mutual independence of the effects of gender and physical activity level. At the same time, the most significant differences for most of the analyzed elements in hair of boys and girls were found in the group with high physical activity.
