If girls are becoming faster sprinters than men like science says, would they be better at most sports too?

No. Women may be getting faster. but in general they are not yet faster then men. Men generally accel at sports over women because of our ancestry. throughout history, men were the hunters. We had to chase and kill animals. Women were caretakers, and worked with children. Through evolution, men needed more muscular strength and endurance. now women are catching up because of a more gender equal swociety, but men still have a 2000 year head start, so I believe iit will still take time for the general population of women to be better athletes than the general population of men. Dont get me wrong. Some women are amazing athletes, better than men. but in general, men are still leading.
