Keep having this conversation: Them: "Evidence says that trans women have an advantage over cis women in sport. It's science!" Me: "What evidence?" T: "Uh..." *searches frantically for evidence* ... T: "We don't need evidence it's obvious"

https://tinyurl.com/y44dxb6b Trans women's skeletons are well preserved through hormone therapy, so pelvic angle (advantageous in many sports inc running/cycling) and bone density (conferring injury resistance) are some advantages we have evidence will be preserved.

I think there are important conversations to be had about trans inclusivity and interesting science to explore physical changes a/w hormonal transitioning more, but claiming there's no evidence a male conformation skeleton stays that way is daft and undermines more valid points.

And how does BMD directly impact athletic performance in a way that can be considered unfair? Do you know of any studies comparing trans women with cis women on this or another point?

I posted in the wrong place- that was meant to reply to your comment that there's no evidence trans women retain male conformation pelvis angle. Given there is no loss of BMD or significant change in bone metabolism, we can safely confirm the common sense knowledge that they do.

I never said that. I said there's no evidence for an unfair competitive advantage in sport (or any advantage for that matter)

As you know there's never going to be an RCT so evidence will be complex & maybe indirect. The Harper study (a not great case control study) showed no stat. sig. drop in performance for trans women but used by IOC to support trans women compete with cis women for example.

You could potentially design an RCT but it would be incredibly complex (waitlist control perhaps). If we're talking about the recent (2016?) study then it did show a drop in performance but since the sample size was 4 it wasn't possible to make any statements statistically

True. Would be interesting but pretty tough to put together! I don't envy the grant writer for that one... Anyway, thanks for civil chat. Twitter makes it hard to talk about the more interesting nuanced side of it all.
