摘　　要：铁元素在人体进行氧分子转运和产生能量方面发挥重要作用,因此是一种对运动训练产生重要影响的微量元素。参与耐力性运动的女性运动员,由于周期性月经的原因,导致机体铁流失,进而影响机体的耐力性运动机能。传统上通过口服补充铁剂来预防治疗铁缺乏。然而这种方法因为其具有副作用并增加铁毒性而备受诟病,因此最近的研究是通过膳食调节增加运动员的机体铁状态。这些膳食铁疗法包括富铁膳食、血红素铁饮食、膳食辅导咨询及新型富铁食品。目前虽然对膳食调节的研究还不多,但是研究文献都支持这样一种观点:通过干预膳食中的铁含量,可以辅助维持女性运动员机体铁状态,特别是在高强度的训练和比赛期间。未来的研究应聚焦在通过膳食调节更高效地提高铁状态的方法上,以及这些方法是否能够在运动训练中产生有利影响。Iron plays an important role in transporting and generating oxygen molecules in ment which has important influence on sports training. Athletes , particularly female athletes participating in endurancesport,ae at increased risk of compromised iron status due to heightened iron losses through menstruation and the iron lossafects the body, s endurance sports function. Conventionally oral iron supplementation is ment of iron deficiency. However,this approach has been criticized because of the side effectoxicity associated with the use of supplements. Thus,more recently there has been a growing interest in using dietary mod-ification rather than the use of supplements to improve iron status of athletes. These diet,heme iron diet,dietary counseling and new iron rich foods. Although there are few studies on dietary regulation, the literature suppors the view that iron levels in the diet can help maintain the iron status of female athletes, especially during intensive training and competition. Future studies should focus on ways to improve iron status more efficiently through diet-ary regulation , and whether these methods can have a favorable impact on exercise training.
