This study primarily aimed to quantify and compare iron status in professional female athletes and nonathletes. Furthermore, this study also aimed to identify differences in iron status according to sporting discipline and explore the relationship between ferritin concentration and weekly training volume in professional athletes. A total of 152 participants were included in this study, including 85 athletes who were members of senior teams (handball, n = 24; volleyball, n = 36; soccer, n = 19; and judo, n = 6) involved at the highest level of competition and 67 nonathletes. A significantly greater proportion (p = .05) of athletes (27%) demonstrated iron-deficient erythropoiesis (IDE) compared with nonathletes (13%). There were nonsignificant differences (p > .05) in the prevalence of iron deficiency (ID; 49% vs. 46%) and iron deficiency anemia (IDA; 2% vs. 4%) between athletes and nonathletes. Similarly, the prevalence of ID, IDE, and IDA was not significantly different between sports (p > .05). Furthermore, training volume was negatively correlated with ferritin concentration in athletes (r: -.464, moderate, p < .001). Professional female athletes are at a heightened risk of IDE compared with nonathletes; therefore, they should be periodically screened for ID to reduce the deleterious effects on training and performance. The similar prevalence of ID, IDE, and IDA found across athletes competing in different sports suggests that overlaps exist between handball, volleyball, soccer, and judo athletes regarding risk of disturbance in iron metabolism.

与非运动员相比,职业女运动员患缺铁性红细胞生成的风险更高。

本研究主要旨在量化和比较职业女运动员和非运动员的铁含量。此外,本研究还旨在根据运动学科确定铁状态的差异,并探讨职业运动员的铁蛋白浓度与每周训练量之间的关系。本研究共纳入 152 名参与者,其中 85 名运动员是高级团队成员(手球,n = 24;排球,n = 36;足球,n = 19;柔道,n = 6)参与最高比赛水平和 67 名非运动员。与非运动员 (13%) 相比,明显更高比例 (p = .05) 的运动员 (27%) 表现出缺铁性红细胞生成 (IDE)。缺铁的患病率(ID;49% vs. 49%)没有显着差异(p > .05)。46%) 和缺铁性贫血 (IDA; 2% vs. 4%) 在运动员和非运动员之间。同样,ID、IDE 和 IDA 的患病率在不同运动项目之间没有显着差异(p > .05)。此外,训练量与运动员的铁蛋白浓度呈负相关(r:-.464,中等,p < .001)。与非运动员相比,职业女运动员患 IDE 的风险更高;因此,应定期对他们进行 ID 筛查,以减少对训练和表现的有害影响。在参加不同运动项目的运动员中发现的 ID、IDE 和 IDA 患病率相似,这表明手球、排球、足球和柔道运动员在铁代谢紊乱的风险方面存在重叠。和 IDA 在运动之间没有显着差异(p > .05)。此外,训练量与运动员的铁蛋白浓度呈负相关(r:-.464,中等,p < .001)。与非运动员相比,职业女运动员患 IDE 的风险更高;因此,应定期对他们进行 ID 筛查,以减少对训练和表现的有害影响。在参加不同运动项目的运动员中发现的 ID、IDE 和 IDA 患病率相似,这表明手球、排球、足球和柔道运动员在铁代谢紊乱的风险方面存在重叠。和 IDA 在运动之间没有显着差异(p > .05)。此外,训练量与运动员的铁蛋白浓度呈负相关(r:-.464,中等,p < .001)。与非运动员相比,职业女运动员患 IDE 的风险更高;因此,应定期对他们进行 ID 筛查,以减少对训练和表现的有害影响。在参加不同运动项目的运动员中发现的 ID、IDE 和 IDA 患病率相似,这表明手球、排球、足球和柔道运动员在铁代谢紊乱的风险方面存在重叠。与非运动员相比,职业女运动员患 IDE 的风险更高;因此,应定期对他们进行 ID 筛查,以减少对训练和表现的有害影响。在参加不同运动项目的运动员中发现的 ID、IDE 和 IDA 患病率相似,这表明手球、排球、足球和柔道运动员在铁代谢紊乱的风险方面存在重叠。与非运动员相比,职业女运动员患 IDE 的风险更高;因此,应定期对他们进行 ID 筛查,以减少对训练和表现的有害影响。在参加不同运动项目的运动员中发现的 ID、IDE 和 IDA 患病率相似,这表明手球、排球、足球和柔道运动员在铁代谢紊乱的风险方面存在重叠。
