This study was undertaken to evaluate sweat copper, zinc, iron, magnesium and chromium levels in 26 adult sportsmen (wrestlers) aged between 17-20 and average weight of 73 kg in Turkey. To eliminate the possibility of intestinal parasites that could be effective on element absorption, all subjects were examined for intestinal parasites. Sweat samples were collected at 50% VO2peak for 30 min while wrestlers trained at room the temperature (~27 ºC, RH=51%) by the whole body method. All samples were analyzed by atomic absorption spectrometry. The mean concentrations of copper, zinc, iron, magnesium and chromium were found to be 28.58±3.3 μg/dl, 42.6±4.0 μg/dl, 109.6±8.5 μg/dl, 53.15±6.72 mg/dl and 10.31±1.31 μg/dl respectively. It appears that substantial quantities of trace elements are excreted in the sweat of those sweating during the training. These observations suggest that excretion of trace elements by sweating induces trace element decrease. Mineral elements, including magnesium, zinc, copper, iron and chromium are required by the body in modest amounts for the maintenance of health and for the development of optimal physiological function. For sportsmen, adequate amounts of these minerals are required for physical training and maximum performance.
