对新战士进行正步训练前后血清Ｃｕ、Ｚｎ－ＳＯＤ及Ｚｎ、Ｃｕ微量元素含量检测。其中１６名训练后出现血红蛋白尿（ＭＨｂｕ），３０名未出现。前者训练后血清ＳＯＤ较训练前明显下降，Ｃｕ、Ｚｎ含量也降低，后者ＳＯＤ及Ｃｕ、Ｚｎ也表现下降趋势。二者血清Ｃｕ、Ｚｎ含量与ＳＯＤ变化均呈现正相关，且与红细胞ＳＯＤ呈正相关变化，而与红细胞ＭＤＡ呈相反变化。推测体内Ｚｎ、Ｃｕ营养状况影响正步训练时抗氧化酶ＳＯＤ的代偿能力。
Determination of trace elements in serum Cu, Zn-SOD and Zn and Cu before and after training new soldiers. Among them, 16 had hemoglobinuria (MHbu) after training and 30 had not appeared. The former serum SOD decreased significantly after training, Cu, Zn content also decreased, the latter SOD and Cu, Zn also showed a downward trend. The contents of Cu and Zn in serum and serum SOD both showed a positive correlation, and positively correlated with erythrocyte SOD, but red blood cells MDA had the opposite change. It is inferred that the nutrition status of Zn and Cu in vivo affects the compensatory ability of antioxidant enzyme SOD during orthostatic training.
