Physical exercise leads to many metabolic, cardiovascular, and muscular changes in the body. The trace elements (TE) zinc and copper are directly involved, as enzymatic cofactors, in many of these processes, especially those related to nutrients metabolism, oxygen transport, and formation of usable energy. The effects of high-intensity physical exercise on plasma levels of CU2+ and Zn2+ in 19 subjects are investigated (9 males and 10 females). Plasma copper concentration decreases, and plasma zinc concentration increases, after exercise, in both sexes. After 30 min recovery, both TE concentration values shifts toward rest values in both sexes. These results only partially agree with literature data, probably because we used the treadmill exercise, which makes many muscles work, whereas other authors made their subjects perform a cycloergometer exercise. Physical exercise causes a marked redistribution of TE (copper and zinc) between body stores, bloodstream, and tissues. The condition of high metabolism may lead to a deficiency of TE, requiring supplementation in order to maintain high level performance.
体育锻炼会使身体发生许多代谢、心血管和肌肉方面的变化。微量元素（TE）锌和铜作为酶的辅助因子，直接参与其中许多过程，尤其是那些与营养物质代谢、氧气运输和可用能量形成相关的过程。研究了19名受试者（9名男性和10名女性）高强度体育锻炼对血浆中Cu2+和Zn2+水平的影响。运动后，男女两性的血浆铜浓度均降低，血浆锌浓度均升高。恢复30分钟后，两性的这两种微量元素浓度值均向静息值转变。这些结果仅部分与文献数据相符，可能是因为我们使用的是跑步机运动，它使许多肌肉参与工作，而其他作者让他们的受试者进行的是蹬力计运动。体育锻炼会导致微量元素（铜和锌）在身体储存部位、血液和组织之间发生显著的重新分布。高代谢状态可能会导致微量元素缺乏，需要补充以维持高水平的运动表现。
