The results indicated high intensity training affected the level of ER of femur in exercise-induced estrous cycle inhibited female rats from post transcription.
Conclusion: All results showed high intensity training affected the integration of bone' structure in exercise-induced estrous cycle inhibited female rats. The results indicated the decreased expression level of OPG/OPGL was the importance ingredient on the change of bone's structure in exercise-induced estrous cycle inhibited rats.
②The decrease of estrogen and progesterone are important reasons of estrous cycle inhibition,and the level of IGF-1 is closely related with the inhibition of estrous cycle.
It has been shown that the level of estrogen were decreased and the level of ER in bone were increased in exerciseinduced estrous cycle inhibited female rats than toose in control. But the expression of ER mRNA in bone were similar with those in control.
