用核分析技术研究儿童运动员补充强化铁剂食品的效果

Study on effect of supplementing iron-fortified food to children athletes by nuclear analyais and blood analyais tecbniques

用中子活化分析、同步辐射Ｘ射线荧光分析和血液分析测定了３７名儿童运动员在分别补充０、８、１６ｍｇ／ｄ的铁（以含葡萄糖酸亚铁的巧克力的形式）三个月后头发和血液中铁含量的变化。结果表明，补铁后男运动员铁蛋白达到正常水平，发铁随补铁量增加而增加，但不成正比。多数女运动员有相似结果．建议每日给儿童运动员补充铁８ｍｇ左右为宜。

The iron content in hair and blood for 37 children athletes who were supplemented with 0, 8 and 16 mg Fe/d, respectively, in the form of ferrous gluconate-containing chocolate for 3 months was determined before and after the supplement by INAA, SRXRF and blood analysis. The experimental results indicated that after the supplement of the iron-fortified food, the ferritin level in blood of the male athletes attained to normal and the iron content in hair was increased with the increasing level of supplement, but not in direct proportion. Most of the female athletes had similar results. It is suggested that supplement of 8 mg Fe/d to a child athlete may be adequate.
