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20m／min，30min／次，2次／天，6天／周，休息1天；第2周25m／min，60min／次，2次／天，6天／周，休息1天；第3周30m／min，90min／次，2彬天，6天／周，休息1天；第4周35m／min，120min／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。
目的：觀察補充納米生血鐵對高彊度運動大鼠鐵代謝相關指標的影響。方法：60隻健康雄性SD大鼠為研究對象，體重（160±10）g，隨機分為4組：A組為安靜對照組（n=15）、B組為高彊度運動對照組（n=15），C組為高彊度運動補充生血鐵組（n=15）、D組為高彊度運動補充納米生血鐵組（n=15）。運動大鼠第1週20m／min，30min／次，2次／天，6天／週，休息1天；第2週25m／min，60min／次，2次／天，6天／週，休息1天；第3週30m／min，90min／次，2彬天，6天／週，休息1天；第4週35m／min，120min／次，2次／天，6天／週，休息1天。在最後一次運動後次日處死動物併取材測試。D組大鼠補充納米生血鐵，c組大鼠補充等量普通生血鐵，A、B組大鼠補充等量安慰劑。結果：大鼠進行4週高彊度遞增負荷運動後，血清鐵、血清總鐵結閤力、紅細胞總數和血色素均顯著下降；而補充納米生血鐵大鼠血清鐵、血清總鐵結閤力、紅細胞總數和血色素水平均顯著升高。

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＂.
