Okay, I just listened to both audio links provided, and that? Is utterly, utterly forced, false, and unnecessary. Is it an intimidation tactic, or a distraction, or just an attention-getting device? I don’t know, and frankly, don’t care. SHUT UP.
You don’t have to be utterly silent when hitting a hard shot, naturally in strenuous situations you’ll vocalize somewhat, but quite being such an obvious prima-donna.
None of those sources support what you said, though. The Harvard link says
Which is what I said.
The Bulletin of Glaciological Research says
Which I’m not sure what to make of.
The Exercise Physiology for Health site says the Valsalva Maneuver is a factor in increased myocardial oxygen demand and a factor in a rise in blood pressure.
I’ll take back the claim about heart attacks, since it is a factor when shovelling, but the Valsalva Maneuver itself doesn’t increase power and nothing in your cites shows that.
I’d like to know if she’s really always been this loud. She started getting a lot of attention during the French Open, but she’d received a few entries into big events before that and I don’t remember hearing about her. Maybe it was seen as less of an attention getter or maybe she was just playing on outer courts and not being taped, but it’s odd.
Nope. Talking during a point is considered a hindrance. It usually results in a warning for the first offense and a loss of point for any further offense. Shrieking and grunting are up to the discretion of the umpire. So far, no umpires are giving warnings for it, so the players are getting away with it.
