研究人员对于以下的事实长期迷惑不解:经过良好训练的运动员,其红细胞压积和血红蛋白低于非运动员,但运动员的循环血红蛋白总量增加。对这一矛盾现象有人提出“运动性贫血”一词。瑞典Sahlgren医院的医师们称,这一名词不恰当,因为不是由于铁缺乏而引起贫血。 43名受过训练的、中距离和长距离赛跑运动员与119名对照者进行比较,研究人员发现,运动员的红细胞压积、血清铁、转铁蛋白饱和 Researchers have long puzzled over the fact that well-trained athletes have lower hematocrit and hemoglobin than non-athletes, but athletes have an increase in circulating hemoglobin. Someone put forward the term “sports anemia” to this contradictory phenomenon. The doctors at Sahlgren Hospital in Sweden say the term is not appropriate because anemia is not caused by iron deficiency. 43 trained, mid-range and long-distance runners compared with 119 controls found that athletes’ hematocrit, serum iron, and transferrin saturation
