Serum zinc was determined using atomic absorption spectrophotometry in 160 training athletes (57 females) in the morning at rest. In 23.3% of the male and 43% of the female athletes, serum Zn was lower than the limit accepted for the normal range (75 microgram/dl or 11.5 mumol/l). The average serum Zn (96.7 +/- 12.6 microgram/dl) and the range of the values found in a control group of 15 young adult males did not differ from the accepted values in the literature. In 22 randomly selected male athletes, serum Zn fractions were determined using polyethylene glycol precipitation at pH 7.1; 22.2% of total Zn was bóund to alpha2-macroglobulin, the ratio being very close to 1 atom of metal per molecule of globulin. The possible reasons that may influence the serum Zn level in athletes are discussed with regard to the present knowledge in both exercise physiology and metabolism of zinc in man.
采用原子吸收分光光度法对160名训练中的运动员（57名女性）在早晨静息状态下测定血清锌。在男性运动员中，23.3%以及女性运动员中43%的血清锌低于正常范围所接受的限值（75微克/分升或11.5微摩尔/升）。15名年轻成年男性对照组的平均血清锌（96.7±12.6微克/分升）及所测值范围与文献中的公认值并无差异。对22名随机选取的男性运动员，采用pH 7.1的聚乙二醇沉淀法测定血清锌组分；总锌的22.2%与α2 -巨球蛋白结合，该比例非常接近每分子球蛋白结合1个金属原子。结合运动生理学和人体锌代谢的现有知识，讨论了可能影响运动员血清锌水平的潜在原因。
