> are the coaches broadly incompetent I think it might be that they're competent with respect to achieving specific athletic goals but incompetent with respect to recognizing (ab)normal development in young women. I'm not an expert by any means, but I get the rather strong impression that elite athletic coaches for young women overwhelmingly either are male or are former elite female athletes themselves. Add that to selection bias for their clients and they might very well have little to no experience working with a normally developing female body.
