【 摘 要 】

The salivary and hair levels of bioelements, such as calcium, potassium, magnesium, iron, zinc, chromium, and selenium, were investigated in 130 children and adolescents, including 35 swimmers, 47 hockey players, 20 fencers, and 28 schoolchildren who did not additionally go in for sports. Atomic emission spectrometry and inductively coupled plasma mass spectrometry were applied. The aim of our study was to investigate the characteristics of macro- and microelemental composition of the saliva and hair of young athletes. The investigation established that that all young athletes showed the high levels of potassium and selenium in their hair, those of selenium and chromium in the saliva, and a significantly low concentration of potassium in the saliva (p<0,05), reflecting the intensity of mineral exchange during physical exercises. Individual characteristics were found in the content of chemical elements in the test biological substrates in relation to the kind of sports: the salivary levels of calcium and magnesium were reduced and the hair level of iron was increased in fencers (p<0,05); and the field-hockey players had higher zinc values (p<0,05). Comparison of the hair and salivary concentrations of bioelements established that there was a statistically significant relationship for potassium (R=-0,72; p<0,001) and selenium (R=0,44; p=0,004). Non-invasive screening studies of salivary and hair minerals are recommended for the early diagnosis of an imbalance in macro- and microelements in young athletes. There is evidence that young athletes should be identified as a group of patients at risk for an imbalance of macro- and microelements.
