摘要
利用高频电感耦合等离子体原子发射光谱法(ICP-PES)测定了小鼠一次性力竭游泳运动后,骨骼肌内铁(Fe)、锌(Zn)、铜(Cu)、硒(Se)、钙(Ca)、镁(Mg)6种元素含量的变化。结果表明,力竭运动后可使小鼠骨骼肌内Ca、Se含量明显上升,Cu元素含量基本不变,Fe、Zn、Mg含量则明显下降。
In this paper,after the mice made exhausted movement (exhausted swim at only one time),in their skeletal muscles the change levels of trace elements such as Iron(Fe)?Zinc(Zn)?Copper(Cu) ?Selenium(Se) ?etc and plentiful elements calcium(Ca)?magnesium(Mg)were determined by ICP-AES.These results show that exhausted movement could result in the increases of the levels of selenium in skeletal muscles. However the levels of calcium and magnesium were significantly decreased.So for the athletes who are in hard training,there is a suggestion that the categories and the levels of supplementary trace element should be distinguished in order to adapt to their physiological need physically.
