i am in a high school girl's volleyball team. I'm fortunate to attend a private school with no mask mandate. Every other team we play againt has to wear masks while playing!
I didnt know if our team would win any games but so far we are winning all of them!
I can't imagine playing with a mask on.
Lol it's not dangerous at all. It's stupid and inhibits their ability to perform at 100% but it won't do any serious damage unless you wear the same one daily for hours on end. Super athletes train under low oxygen environments all the time. It's why boxers from higher elevations tend to have endless gas tanks. Their body is used to performing under shitty conditions and when they compete in normal elevations they perform even better than they usually do.
