摘　　要：目的:观察补充纳米生血铁对高强度运动大鼠铁代谢相关指标的影响。方法:60只健康雄性SD大鼠为研究对象,体重(160±10)g,随机分为4组:A组为安静对照组(n=15)、B组为高强度运动对照组(n=15),C组为高强度运动补充生血铁组(n=15)、D组为高强度运动补充纳米生血铁组(n=15)。运动大鼠第1周20 m/min,30 min/次,2次/天,6天/周,休息1天;第2周25 m/min,60 min/次,2次/天,6天/周,休息1天;第3周30 m/min,90 min/次,2次/天,6天/周,休息1天;第4周35 m/min,120 min/次,2次/天,6天/周,休息1天。在最后一次运动后次日处死动物并取材测试。D组大鼠补充纳米生血铁,C组大鼠补充等量普通生血铁,A、B组大鼠补充等量安慰剂。结果:大鼠进行4周高强度递增负荷运动后,血清铁、血清总铁结合力、红细胞总数和血色素均显著下降;而补充纳米生血铁大鼠血清铁、血清总铁结合力、红细胞总数和血色素水平均显著升高。Objective： To observe the effects of ＂iron nutrient in nanometer＂ supplementation on iron metabolism after high intensity exercise. Method： 60 healthy male SD rats are randomly divided into four groups ： no - exercise group A （ the control group, n = 15 ） , exercise group B （ the control group, n = 15 ）,exercise group C （iron nutrient, n = 15 ） and exercise group D（ ＂iron nutrient in nanometer＂ supplementation, n = 15）. Rats run 30 minutes at speed of 20 m/min,twice a day, exercise 6 day/week and rest 1 day/week in the first week. Rats run 60 minutes at speed of 25 m/min, twice a day, exercise 6 day/week and rest 1 day/week in the second week. Rats run 90 minutes at speed of 30 m/min,twiee a day, exercise 6 day/week and rest 1 day/week in the third week. Rats run 120 minutes at speed of 35 m/min ,twice a day, exercise 6 day/week and rest 1 day/week in the fourth week. After sports training for 4 weeks, rats were killed. Blood of the rats is taken to analyze the index of RBC, hemoglobin, count RBC, hematocrit, serum iron, total iron binding capacity and trans-ferrin saturation. Rats in D group were fed beverage containing ＂iron nutrient in nanometer＂,and rats in A and B groups were fed placebo, and rats in C group were fed beverage containing iron nutrient. Conclusion ： After 4 weeks of training, the level of Hb, RBC, serum iron, total iron binding capacity, transferrin saturation of the B group are significantly lower, but the level of Hb, RBC, serum iron, total iron binding capacity, transferrin saturation of the D group increased significantly after fed beverage containing ＂iron nutrient in nanometer＂.
