And because women often restrict their diet in an effort to control weight, they may not consume enough iron-rich food, and are liable to experience a deficiency. "The average woman takes in only two thirds of the recommended daily allowance of iron," notes another expert. "For a woman who already has a poor iron status, any additional iron loss from exercise may be enough to tip her over the edge into a more serious deficiency," notes the expert. Exercise can result in iron loss through a variety of mechanisms. Some iron is lost in sweat, and, for unknown reasons, intense endurance exercise is sometimes associated with bleeding of the digestive system.
而且，由于女性常常为了控制体重而节食，从而未能摄取足够的含铁丰富的食物，结果可能导致缺铁。 另一名专家指出，“普通女性每天摄入的铁只是应摄入量的三分之二。”他指出，“对于那些已经缺铁的女性，任何因锻炼而产生的更多铁质流失都足以导致体内缺铁状况的恶化。” 运动可能通过多种机制导致铁流失。有些铁随汗液流失。另外，由于某些未知的原因，高强度的耐力运动有时会引起消化系统内出血。
