When I first read your post I had a gut feeling that we are from the same country. And I was right! It makes me sad too that even if our country is well known of happy childhoods and children rights taken seriously we still have so much to do to root out the inappropriate and damaging coaching methods in certain sports like gymnastics (and not just WAG, I think AGG and rhythmic might be even worse) and figure ice skating.
I have two friends too who were National Team members back in the day (5-10 years ago) and they tell the same story that you have heard. It makes me super scared to hear those things, because I know that some of the coaches who were in the camps with them are still going to the camps. And we are now attending too since one of my gymnasts made the team.
But I have also heard more positive things about the culture nowadays. They don't weight girls anymore, they don't go to their rooms looking for "secret" snacks, they don't hover behind them in the cafeteria to see if they are drinking juice or having a dessert. And making kids practice when injured is not so common anymore. And the national gymnastics federation is now trying to consciously lead the way to other direction from the traditional East European / Russian methods that took place for a long time because the majority of the National Team coaches came from those countries. The trend has been that the promising, talented juniors quit before they even reach the adult divisions.
It's well known "joke" in the gymnastics community that all the coaches seem to be somewhat insane. When young coaches first start they have stars in their eyes and they are willing to do everything they can to get their young girls to the National team or developmental team for kids age 10-12. I have seen this so many times. Some of those coaches have become good and "sane" later on though.
Our club is not like that. We are following our own path and doing things very differently from all the "top" gyms in the South. We have participated to the developmental camps for younger kids and for the secondary school aged kids and the camps have been mostly good because our coaches always put our own gymnasts' well being first. But at the camps I always notice the difference between coach-gymnast communication, rules and expectations from the coach between those highly competitive clubs with big teams and then us and some other smaller clubs that don't take it so seriously. Those highly competitive clubs seem to treat their kids like a little army.
I want to give kids (all ages!) the freedom to think on their own, make mistakes and learn from them, participate everything they can in their own coaching and learn to stand up for themselves and each other. I want my kids to always be open with me, but I understand that it doesn't work the way that you just tell them to do so. We really need to be worthy of their trust and always stay humble about that. It's our fault if they feel need to lie to us or not tell the truth. I have to build an environment where they feel safe to tell me if they are not comfortable with something, if they are scared or hurt or if they lack the motivation.
I have heard zillion times coaches be angry at the kids for not telling they are hurt until the injury has gotten super serious. This makes me angry, because I think the coaches are still part of the problem. They may SAY that they don't want their gymnasts to practice injured, but their everyday actions don't stand by that statement. They might say they are not focused on scores and trying your best is enough but their body language tells another story at meets when the kids don't succeed or win. They may say that school comes first always but if a parents refuse to send their kids to a camp that takes places during the school week they get very upset.
As you are a teacher of many highly competitive young athletes, I encourage you to read the signs in the kids' behavior very closely. Monitor their reactions and language they use when they talk about food. Ask about their sport and encourage them to tell what was best and what was worst at the camp or competition. A teacher may sometimes be the only person they are willing to tell their worries, because teacher is a neutral adult and usually known to be always righteous. And the teacher might even spent more time with the kid than their own parents.
BTW, have you read this Aamulehti article about gymnastics culture in Tampere? It makes me sick in the stomach to read that all this craziness was still taking place at least in 2016. I doubt that it has gotten that much better. Link Removed
