| 摘 要： | 以不同运动模型的大鼠为实验对象，分析其子宫胞浆ＥＲ、ＰＲ含量并与对照组的数值比较。结果表明，长期力竭组子宫ＥＲ、ＰＲ显著升高，ＥＲ／ＰＲ比值也有升高趋势；急性力竭组无显著改变。从受体水平的异常变化支持了以往有关长期大强度负荷导致雌性动物动情周期抑制或女运动员月经失调的论断。提示，子宫ＥＲ、ＰＲ变化可能需要一定的时间过程。

| Abstract: | The present study analyzes effects of exercise on contents of uter ineest rogen receptor(ER) and progesterone receptor (PR) in rats. Results show that uterine ER, PR and ER/ PR increase significantly in chronic exhaustive group while the three indicators don't increase in acute exhaustive group. The paper indicates that it is long-term intensive training not acute intensive exercise that cause estrous cycle dysfunction in female rats. |
