How odd for you to make up something completely different to what I said and then attribute it to me.
Can't you correlate stress fractures to running a high number of 3000m and 5000m track races while still a child? Are you unaware that human bones and musculature are still forming then and that stress should be limited and coupled with plenty of rest...to avoid stress reactions?
You seem to think that normal maturation that occurs in all female athletes is somehow a barrier, rather than training. Mary hasn't developed physically in a way which would prevent elite level athletics, but like every athlete, she needs to train and watch her diet. That doesn't mean losing weight, it means eating healthily and controlling what she eats for most of the year so that she develops the physique of an elite level athlete. We already know that American athletes think eating fast food from burger stalls after training is normal but again, its not. Plenty of people start out with bodies that don't resemble elite level athletes. You are suggesting that Mary is in some special class that makes this impossible? What evidence do you have for this?
As to the other poster who thinks that obsessing about children and teenagers is normal outwith the US - no, its not. I don't think anyone in my country obsessed about Jakob Ingebrigtsen in the way that people do on this board. Jakob is an outlier anyway - all of the Ingebrigtsen family seem to mature early athletically and then tail off when in their mid to late twenties. That might also be due to starting training hard so young as well but even so there was more control of what Jakob was doing and his progression whereas Mary was thrown in the deep end and the American public assumed that if she could run those times as a child, she would run even faster as an adult. In reality, she was already running at her limit while her body was still growing and its unbelievable that her parents, coaches and the public thought this was a good idea.
But yes, you go and label it on her "not having an athlete's body" and keep making the same mistakes with the next Mary Cain that comes along. While American athletes continue to win almost nothing at elite level despite your massive population.
