If you wonder if they are slower and such, then no. They the same stats as the guys since you aren't able to play a women's team against a men's team. They seem to have the same animations as the men too.
Sounds like a pretty pointless upgrade in the end.
Well, top male athletes are commonly acknowledged to be fast/stronger than top female athletes - I was more curious as to whether female players are technically poorer compared to their male counterparts in the game, which is a bit more controversial.
