> A coach can correct mistakes without yelling.

Are you a professional coach or just think it would work this way?

The athletes we are discussing are already selected as fit for the specific sport. All of them are very tolerant to stress from the training and competition. Unless stress of not doing exercise (correctly) is higher than stress from doing it (correctly) there won't be progress.

What for an outsider looks like abuse, for athletes is within tolerable limits.

Not the parent nor a professional coach but you wrote: "my daughter came to me in tears and complained coach is yelling at her".

That doesn't sound like being selected for stress tolerance. That sounds a lot more like stress tolerance is being mentally beaten into them.

Selection is for physical capabilities (experienced coaches are actually looking at both parents in addition to child assessment). Stress tolerance is built up gradually as a side effect.

Does it matter? Surely having a reasonable environment is a far higher priority than "being a champion".
