Not on the whole growth spurt issue, my loving mother covered that lol, but on the weighing and measuring girls. All I can think of is Christy Heinrich. I think it's great that gymnastics has started to move away from that 80s and early 90s super tiny and skinny ideal with loads of horrible stories about eating disorders and coaches calling girls fat, etc. Well maybe not in the eyes of the public but they never understand gymnastics anyway. If coaches are worried about growth spurts... well can't they just look and see? I know if you see a girl everyday it's harder to see the 4 inches and 15 pounds she's gained growing, but there's no reason to measure the girls for that. A good coach knows his/her athletes well enough to see when they're uncomfortable with a skill for whatever reason, growth, fear, whatever, and they can adjust their coaching to help them.
My coaches were great about body issues, no forcing only leos so girls got uncomfortable, no comments about size at all, really supportive, etc. But I still knew a girl on my optionals team who struggled with bulimia. A lot of it was because of her home life and her super competitive parents (the kind that take their kids every weekend on 40 mile bike rides and go for 10 mile runs in the snow and compete in triathalons, one was a former college skier who coached at Ski Club Vail, which is like WOGA's program for elite skiers). It was really sad and she ended up dropping out and ended up going down a bad path. Even our cheerleading coach for high school would regularly tell girls they were getting too big to fly, myself too. We all crash dieted together, and would have diet coke and an apple or something for lunch thinking it's not like we had real eating disorders. It's really sad in retrospect our coach passively encouraged that. By the time girls are teenagers they're bombarded with enough pressure to be super skinny. Forcing the issue with younger girls only makes that worse.
It's really easy to talk about weighing and measuring and molding girls body types until you actually know someone who's had a bad eating disorder.
