As a rower, I am against this rule. When you're doing a sprint, you grunt or use some explosive to get out as much air as possible as fast as possible so that you get more air faster. It's not like you're doing it to show off, you're doing it so you don't pass out from lack of oxygen, or even worse, have to stop in a race. While I don't understand screaming, grunting is fine with me. Also, isn't their alarm louder than any grunts people could be making, defeating the idea behind their policy in the first place? After all, that low key grunting must be WAY louder than some 80 db alarm.
