When you are developing as a young player and the top players on the tour or at your academy are grunting loudly, you tend to be influenced. Some consciously pick it up while others are not even aware that it has crept into their game. Nick B and others should have addressed this long ago -- by teaching and encouraging proper breathing techniques while making minimal sounds.She didn't force anyone to do it. It's the fault of every individual person who does it. Plus, she's the one who got flak, was sent the message "this isn't okay", criticized by commentators, so if anything her experience would have been a reason for players not to do it.
The heat's probably a factor. 100 F in Melbourne right now. Undoubtedly much hotter on the court.I don’t know if Simona has ever been this loud.
