Can yelling improve the speed of a pitch or a collision?

I was watching different episodes of “Sports Science” which has long been a favorite show of mine and ran across this. I know that generally, pitchers and other position players trying to make a play will either be yelled AT for yelling or will be looked at pretty funny. But imagine if the same facts in the video above applied for baseball as well. A faster fast ball, the extra push that you need to pummel that catcher when he’s waiting for you at home plate. Imagine if there was something so simple as yelling to give you that edge that you might need to overcome. I know the next time I’m alone, I might just try and track my fastball both yelling and holding my tongue. It’ll be interesting.

If you don’t feel like watching the entire thing, the physics comes into play about 5 minutes and 30 seconds in the video

not exactly yelling for me, but grunting
