极量运动对小鼠体内4种器官微量元素影响的性别差异

利用高频电感耦合等离子体发射光谱法（ＩＣＰ－ＡＥＳ）测定了小鼠极量运动（一次衰竭性游泳运动）后，体内肝脏、心脏、脑、骨骼肌４种器官内锌（Ｚｎ）、铜（Ｃｕ）、铁（Ｆｅ）、锰（Ｍｎ）、硒（Ｓｅ）、钼（Ｍｏ）等微量元素及钙（Ｃａ）、镁（Ｍｇ）两种宏量元素的含量变化，并与安静组及雌、雄个体之间进行了比较研究。结果表明：（ｌ）雌雄个体微量元素含量及分布具有一定程度的性别差异；（２）极量运动后微量元素的变化出现明显的性别差异。结果提示，极量运动会促使体内微量元素重新分布，并表现出性别特征。建议大运动量训练期间，男、女运动员饮食中微量元素补充应有所区别，以适应身体的生理需要。

Sexual Difference in the Trace Elements in Four Organs of Mice after Exhaustive Swimming

In this paper,by using ICP-AES method,we determined the content of trace elements, such as Zn, Cu,Fe,Mn,Se,Mo,and oth- er elements such as Ca, Mg in the liver, heat, brain,skeletal muscles of mice, after exhaustive swimming,The results were compared with the control and between the female and male mice.The results indicate that there are obvious sexual differences in distribution and contente of the trace elements between male and female for after exhaustive swimming.It is suggested that exhaustive exercise may cause the redistribution of trace element in the body with sexual differences.Accordingly,the supply of trace element should be dif- ferent for male and female athletes during exercise in order to appropriately meet their physiological needs.
