Again, hotly debated topic and even by their own results there ARE differences. Lean muscle mass IS greater in trans female athletes. Doping is easier to conceal in trans male athletes.

And I don’t know what should be done about sports, but that’s because I’m not a sports medicine expert and clearly, neither are you. It’s great that you really like sports and value the integrity of the field or whatever, but your feelings about your hobby should have no bearing on wider social policy.

Bold assumption that I didn’t go to college and don’t have a bachelors in Exercise Science. I mean all I’ve ever wanted to do in life is train athletes lol.

But hey you can believe what you want and I’ll certainly continue believing what I do. I think your problem is largely that most sports at the moment, the sports medicine experts ARE advocating against trans athlete participation. The opinions of the researchers and scientists in those studies concluded that lean muscle mass doesn’t result in a competitive advantage. That is totally NOT the consensus of the field at large, and why people educated on the subject like myself are leery of the political impact on studies like this. Lean muscle mass as percentage of body weight remains the best predictor of physical ability. That’s not even addressing musculo-skeletal differences which deals with how muscle attaches to the skeleton or how muscle structurally forms, which IS different between the sexes, and unfortunately, presently HRT doesn’t affect, those differences persist regardless of puberty blockers present in prepubescence. So… tech has to get better to transition more completely.
