耐力运动对女运动员铁代谢及铁调素的影响

为探索耐力运动对女运动员铁代谢及铁调素的影响,揭示运动时铁代谢的变化规律,并为防治运动性贫血提供依据和参考,对12名参加2015年衡阳市元旦环城赛跑(全长约6 000m)的大学女运动员,分别于赛前、赛后即刻、赛后1d、赛后3d各取静脉血5mL,测试血清铁、铁蛋白、Hepcidin和白细胞介素6(IL-6).结果显示,赛后即刻运动员血清铁和IL-6比其他各时间点显著上升(P0.05),赛后1d运动员血清Hepcidin比其他各时间点显著上升(P0.01).这说明耐力运动对女运动员血清铁、Hepcidin和IL-6产生了即时性影响,建议经常监控女运动员铁代谢相关指标及铁调素水平.

Effects of Endurance Exercise on Iron Metabolism and Hepcidin in Female Athletes

This study aims to reveal the changes of iron metabolism and provide reference for the prevention and treatment of sports anemia by exploring the effects of endurance exercise on iron metabolism and hepcidin in female athletes.5 mL venous blood was taken from 12 collegiate female athletes before,immediately after,1 day after and 3 days after the 6-km round-the-city race of Hengyang in Jan.1,2015.Tests of serum iron,serum ferritin,hepcidin and IL-6 in the blood samples showed that immediately after the race,the levels of serum iron and IL-6 rose significantly (P<0.05) compared with those at the other time points;one day after the race,the serum hepcidin levels in the athletes were significantly greater (P<0.01) than those at the other time points.It can be concluded that the endurance exercise produced transient effects on serum iron,hepcidin and IL-6 in female athletes.Therefore the iron metabolism relative indexes and hepcidin levels in female athletes should be frequently monitored.
