营养补充对运动性贫血大鼠红细胞指数、血清铁、铁蛋白及转铁蛋白指标影响的研究

Effects of Nutrition Supplement on Erythrocyte Indexes, Serum Iron, Ferritin and Transferrin in Rats of Sports Anemia

运动训练导致铁代谢紊乱是造成机体造血机能下降的重要因素之一。实验结果表明:长期递增负荷跑台运动导致运动组大鼠红细胞指数显著低于对照组,出现运动性贫血状态,血清铁呈现降低趋势,血清铁蛋白显著降低,血清转铁蛋白显著升高,机体铁代谢呈现紊乱状态;营养干预后的运动+营养组红细胞指数、血清铁和铁蛋白浓度显著高于运动组,而血清转铁蛋白浓度显著低于运动组,说明营养补剂可以明显改善由于运动训练所引起的铁代谢紊乱状况,并可以明显提高大鼠的血红蛋白浓度。

Iron is the required microelement supporting life and is the main component of hemoglobin. Thus iron has affinity with exercise capacity. Iron metabolism turbulence induced by exercise is one of causes of hematopoietic hypofunction. Results of the experiment showed that long-term treadmill exercise of progressive loading significantly decreased levels of erythrocyte indexes, serum iron, serum ferritin and significantly increased serum transferrin level. Nutrition supplement could significantly retard the variations, and Exercise + Nutrition group have higher levels of erythrocyte indexes, serum iron, serum ferritin and lower level of serum transferrin than Exercise group. The results indicated that nutrition supplement have function of prevent and cure on iron metabolism turbulence induced by exercise, furthermore significantly enhance hemoglobin level in rats.
