Sports and Your Period

Or, “Athletic Performance and the Monthly Cycle.” One takeaway:

…when women’s estrogen levels were at their highest, around the time of ovulation, they landed subtly differently while hopping than at other times of the month. Their feet splayed, the arch collapsing just a little bit more than it did when their estrogen levels were lower. The women also seemed, to a small degree, wobblier.

All those eggs falling out. But women apparently hang on to the benefits of fitness longer than men do when we stop exercising, presumably because our bodies are designed to relax for long stretches of pregnancy, so it’s a tie, they say.
