上海市优秀运动员血清矿物质含量检测及相关性研究

Detection of serum levels of mineral substances for Shanghai elite athletes and study on their correlations

目的测定上海市优秀运动员血清铜、锌、钙、铁含量并为建立运动员血清元素参考值提供依据。方法抽取上海市优秀运动员45名,采用称重法进行膳食调查,原子吸收分光光度法测定血清铜、锌、钙、铁含量。结果不同性别运动员血清铜差异有统计学意义;不同运动项目运动员血清铁的差异有统计学意义;不同运动项目运动员膳食摄入铁、锌、钙、蛋白质、碳水化合物、维生素C、膳食纤维的差异有统计学意义。血清铜和能量、碳水化合物、维生素C呈正相关,血清铁和血清钙、膳食钙、碳水化合物呈正相关。结论上海市优秀运动员血清元素与正常人参考范围并不完全相同,为保障运动员身体健康,需尽快建立不同地区不同项目运动员血清铜、锌、钙、铁的正常参考范围。

Objective To detect serum levels of copper,zinc,calcium,and iron for Shanghai elite athletes and to provide evidences for establishing serum element reference values for athletes.Methods A total of 45 athletes were selected.The nutrients were investigated by the dietary survey and the serum levels of copper,zinc,calcium,and iron were detected by the atomic absorption sepectrophotometry.Results The difference of serum copper of male and female athletes was statistically significant.The differences of serum iron of athletes of different sports were statistically significant.The differences of zinc,calcium,iron,protein,vitamin C,carbohydrate,and dietary fiber intakes of athletes of different sports were statistically significant.The serum copper was positively correlated to energy,carbohydrate,and vitamin C.The serum iron was positively correlated to serum calcium,dietary calcium,and carbohydrate.Conclusion The reference ranges of serum elements of Shanghai elite athletes and normal people are not exactly the same.In order to ensure the health of athletes,reference ranges of serum copper,zinc,calcium,and iron for athletes of different sports and from different areas should be established.
