Obviously this won’t work for all sports, but things like football, track, soccer, it would allow for de-gendered team, even allowing athletes with the skills but not the genetically-endowed physical attributes to have a place to play.
Note: I know very little about sports and being on a sports team, so please point out anything that doesn’t make sense.
When it comes to martial arts, skill does though. That’s why I got my ass handed to me by a 16 y/o girl who is much smaller than me.
Skill matters. But you get enormous leverage by simply being longer limbed and larger.
Practice a bit and you’ll be beating up 16 year old girls in no time. But even at their peak, women martial artists will struggle with mid-level male peers because they lack the raw physical features that move another body.
It’s the difference between a person firing a pistol and a rifle. Marksmanship only gets you so far. Then you really just need a longer barrel.
With enough practice you could even beat up 17 year old girls!
