摘　　要：运动性贫血是体育运动中常见的现象,影响着运动员运动状态和竞技成绩.通过含铁蛋白功能性食品的摄入来调整运动员机体铁代谢,提升运动代谢水平成为一个有效的方式.以蚯蚓为原料,采用聚乙醇-硫酸铵双水相萃取提取液血红蛋白,经透析、离心获得高品质生物肽含铁蛋白产品,加入红枣和蜂蜜来制备一种功能性食品.将制备的功能性食品应用于运动性贫血大鼠中,分析大鼠运动状态下的血细胞、血红蛋白、转铁蛋白等参数.研究结果表明:大负荷跑台运动造成大鼠血清铁、血清铁蛋白下降,转铁蛋白上升,血清铁蛋白、转铁蛋白与血清铁变化呈高度相关性,可通过转铁蛋白与血清铁蛋白表征机体代谢情况.加入功能食品后的跑台运动+营养组贫血大鼠血清铁、血清铁蛋白含量明显提高,血清转铁蛋白含量下降管.通过改善机体铁代谢指标提高大鼠铁储备能力和铁代谢稳定性,对缺铁性贫血具有良好作用.Sports anemia is a common phenomenon in sports,affecting the athletes’physical health and competitive level seriously.Taken ferritin-containing functional foods is a effective way to improve athletes iron metabolism and sports metabolism.this paper takes earthworms as raw materials,used polyethanol-ammonium sulfate to extract hemoglobin,through dialysis and centrifugal obtained high-quality biological peptide,and adding dates and honey achieveed a functional food.The functional food was applied to rats with sports anemia,and determined blood cells,hemoglobin,transferrin.The results showed that the decrease in serum iron,serum ferriin and serum ferrin showed high correlation,the metabolism could be characterized by transferrin and serum ferriin.After adding functional food,serum iron and serum ferrin content were significantly improved,serum transferrin content decreased tube,improved rat iron reserve ability and iron metabolism stability through improving the body iron metabolism indicators,and had a good effect on iron deficiency anemia.
