Coming from a place of curiosity not knowledge with this. Is it not true that strength roughly matches testosterone levels and that is bimodal in the population? Could what we call women’s sports today not be defined on that axis instead?
It's not perfectly bimodal. Some people are also more and less sensitive to testosterone. The average woman produces testosterone (I know, crazy) with some conditions like polycystic ovarian syndrome causing their testosterone production to go into overdrive. Some sports actually do test for testosterone in order to determine eligibility (I believe volleyball?) Also, interestingly enough, people that do estrogen inje…
In theory.
The problem is that for example in women boxing these people are overrepresented. This indicates that testosterone is possibly not the only answer, and we don’t know the full picture AFAIK. But of course it’s also possible that simply Y chromosome causes changes in behavior and not physical performance, and it’s more likely that they like boxing more. We don’t know.
The current best proven differentiator AFAIK is testosterone level and whether their body can process that.
