【摘要】 目的:探讨夏训对优秀运动员铁调素等铁营养状况以及IL-6的影响。方法:广东省优秀皮划艇运动员26人(男15人,女11人)参加测试,调查夏训前和夏训后血红蛋白、铁调素、可溶性转铁蛋白受体、血清铁蛋白、可溶性转铁蛋白受体/log铁蛋白、血清铁、总铁结合力、转铁蛋白饱和度以及白介素6变化情况。结果:夏训后,男运动员组铁调素和可溶性转铁蛋白受体极显著上升(P<0.01)、血清铁蛋白极显著下降(P<0.01),可溶性转铁蛋白受体/log铁蛋白显著上升(P<0.05),总铁结合力显著下降(P<0.05),白介素6极显著上升(P<0.01)。女运动员组血红蛋白显著降低(P<0.05),铁调素和可溶性转铁蛋白受体极显著上升(P<0.01),血清铁蛋白极显著下降(P<0.01),可溶性转铁蛋白受体/log铁蛋白极显著上升(P<0.01),白介素6极显著上升(P<0.01)。结论:夏训可引起运动员炎症因子升高、铁调素升高,导致功能铁不足;铁调素介导的铁代谢紊乱可能是运动性低血色素发生的重要原因。更多还原

【Abstract】 Aim to investigate the effect of summer training on hepcidin,iron status and IL- 6 in elite rowers. Methods 26 elite athletes from Guangdong( 15 male,11 female) participated in this study. Changes in hemoglobin,hepcidin,soluble transferrin receptor,serum ferritin,soluble transferrin receptor /log ferritin,serum iron,total iron binding capacity,transferrin saturation and interleukin- 6 status before and after summer training were compared. Results After summer training,in the male group,hepcidin and soluble transferrin receptor were extremely increased( P < 0. 01),serum ferritin was extremely decreased( P <0.01),soluble transferrin receptor/log ferritin was significantly increased( P <0.05),total iron binding capacity was significantly decreased( P < 0. 05),interleukin- 6 was extremely increased( P < 0. 01) 。In the female group,hemoglobin was significantly decreased( P < 0. 05),hepcidin and soluble transferrin receptor were extremely increased( P < 0. 01),serum ferritin was extremely decreased( P < 0. 01),soluble transferrin receptor /log ferritin was extremely increased( P < 0. 01),interleukin- 6 was extremely increased( P < 0. 01). Conclusion summer training could increase inflammatory factor and hepcidin,and may cause functional iron deficiency. Iron metabolism disorder media by hepcidin may be a key factor of sports anemia.更多还原
