摘要
本文用同步辐射X射线荧光法测定了4名运动员头发中的铁、锌、钙等微量元素,以头发生长每5天为一测量点。结果表明运动员头发中铁相对含量与运动量有关,而锌、钙相对含量与运动量无明显关系。证实了运动是运动员易患缺铁症的原因之一。
Trace elements Fe, Zn and Ca in hair samples taken from four athletes have been de-termined by using SR X-ray fluorescence analysis technique. Each sample is scanned point by point at 1.5mm of interval, which corresponds to 5 days of hair growth. Preliminary results show that the change of iron content in hair is related to exercise capacity of athletes, but no observable change is found for Zn and Ca content. It is verified that sport is one of the causes leading to iron deficiency of athletes.
