In brief: As many as 80% of female long-distance runners show iron deficiency. One explanation is RBC fragmentation due to mechanical trauma. In this study, radiolabeling was used to measure RBC survival rates in six iron-replete female marathon runners. In addition, tests for urinary hemosiderin were conducted in a search for secondary evidence of RBC damage. Radioactivity counts on blood samples drawn before and after a standard 26-mile marathon failed to disclose traumatic RBC fragmentation, and the tests for urinary hemosiderin were negative. Other possible factors in iron deficiency, such as diet, therefore merit consideration.
多达 80%的女性长跑运动员存在铁缺乏。一种解释是由于机械性创伤导致 RBC 破碎。在这项研究中，使用放射性标记来测量六位铁充足的女性马拉松运动员的 RBC 存活率。此外，还进行了尿铁血黄素检测，以寻找 RBC 损伤的次要证据。在标准的 26 英里马拉松比赛前后抽取的血样的放射性计数未能揭示创伤性 RBC 破碎，尿铁血黄素检测也呈阴性。因此，铁缺乏的其他可能因素，如饮食，值得考虑。
