本文通过对20名女子田径运动员进行随机对照实验,观察高住低练过程中血清转铁蛋白受体(sTfR)、促红细胞生成素(EPO)、血红蛋白(Hb)和网织红细胞数(Ret)的变化。结果发现对照组运动员在训练中各时相点上述指标均无明显变化。高住低练组运动员血清EPO水平第3天、第7天和第2周较实验前显著增加,但4周后恢复到实验前水平;sTfR在第7天有增加趋势,第2周与实验前比较有高度显著性差异,高住低练结束后1周有所下降,但仍高于实验前水平;高住低练第7天Ret显著增加,但4周后有所下降;第2周Hb较实验前显著增加,且持续至高住低练结束后2周。结果表明在高住低练过程中,sTfR能反映EPO的变化,但在时相上有差异。sTfR可能更能反映高住低练过程中红细胞的生成状况。
In this paper, 20 female track and field athletes were randomized controlled to observe the changes of serum transferrin receptor (sTfR), erythropoietin (EPO), hemoglobin (Hb) and reticulocyte count (Ret) The change. The results showed that the control group of athletes in training at all times the above indicators had no significant change. The level of serum EPO in high and low exercise group increased significantly on the 3rd day, the 7th day and the 2nd week than that before the experiment, but returned to the pre-experiment level after 4 weeks. The sTfR increased on the 7th day, There was a highly significant difference before the high living low training 1 week after the decline, but still higher than the pre-experimental level; high and low on the seventh day Ret increased significantly, but decreased after 4 weeks; the first two weeks Hb significantly increased before the experiment, and continued to live high and low training 2 weeks after the end. The results showed that sTfR could reflect the changes of EPO during the period of high living and low training, but there was a difference in time. sTfR may reflect the status of erythrocytes during high and low exercise.
