运动员在加大运动量训练,尤其在集训初期的不适应阶段血红蛋白含量下降,这一事实引起了运动员(特别是耐力项目)注意自己血红蛋白含量的变化;当他们了解到铁营养不足使血红蛋白的生成量减少时,极为重视铁营养的补充并把“铁”看作为一种“生力物质(ergogenic substance)”有一定的理由。“铁”作为治疗萎黄病的药物已有长远的历史,但至今缺铁和缺铁性贫血问题在世界各国仍普遍存在。美国青年健康妇女中铁营养缺乏者高达20%,儿童缺铁者平均占 The fact that athletes’ hemoglobin levels have decreased during periods of increased training, especially at the beginning of the training period, has caused athletes (particularly endurance events) to notice changes in their own hemoglobin levels; when they learned that iron malnutrition causes hemoglobin production When declining, the emphasis on iron supplementation is very much attributed to “iron” as an “ergogenic substance.” “Iron” has a long history as a drug for the treatment of chlorosis, but so far the problems of iron deficiency and iron deficiency anemia are still widespread in many countries in the world.
