This seems much more likely to me, the first point, not necessarily the explanation at the end.
So much of climbing the ladder in athletic competition is about surviving each rung of physical and mental hardship. Talent gets you on the ladder but the work too keep climbing gets more and more grueling with each step. At the upper echelon of athletics are people who are basically clinically obsessed and had the good luck to make it through critical development years relatively healthy.
I think that's the truth of high level athletics and most of the time people who are involved in them are so convinced they're the lottery winner no amount of warning can stop them and when, in most cases, they come up short, the previous warnings hit them like a truck.
Now, if this woman in the article is correct, a new approach to female athletics must lead to an increase in performance and she'll revolutionize women's sports. Otherwise, she's just another person warning young athletes that they probably won't make it and the torture they're going through probably isn't worth it.
