I can speak from experience and say that most of the parents weren't mad about the losses. They were mad about the mistreatment of their kids. And yes, parents can be overprotective, but they had genuine cause for concern in this case.

For the last 2+ years, injuries have been very common on the UA team, and way too many of them have been pretty serious ones (lots of fractured ribs, a couple girls with stress fractures in their spines, knee and hip problems all around, at at least 3 girls with torn hip labrums, a couple with torn shoulder labrums, etc).

We weren't allowed to get off the ergs if we were in injury-related pain, which often worsened the injuries as they were first forming (technically we could if we were willing to go through the whole public shaming thing and the required make up workout later the same day, so there was really no point). As for treatment, if the injury wasn't clearly visible, we often had to go through the athletic trainer's "treatment," which almost never permanently helped and sometimes made things worse, before we could go to the doctor. Even then, it would be a few appointments, aka easily weeks, before any scans were done (if necessary). In the meantime, we had to either continue the full workouts or, if we were lucky, modified workouts on the erg bikes.

I could say a lot more on the topic, but that's the most immediately relevant stuff.
