I don't know about that. But once, with a few buddies, we tried to push start a car and it only worked when we started yelling.
Probably your sick martial arts skills tbh
Yelling (and being around other yelling people) would dump more adrenaline into your bodies and effectively give you all a potentially significant short term strength boost.
War cries are a thing for actual reasons beyond intimidation, lol.
I mean kind of, it's mostly that your diaphragm releasing adds a sort of "push" to your blood.
Like, if you're stretching and you wanna stretch a little further you breathe out. I'm a little fuzzy on the biology of it all but it has something to do with that
I think we are basically both right.
Doing outwardly aggressive things like yelling and screaming does release adrenaline, and that will basically give you increased pain resistance, strength, better/faster reflexes.
It also raises your heart rate and thus increases blood flow and oxygenation levels.
I don't know that moving your diaphragm substantially would... directly somehow move your blood more or faster, but it would trigger a bunch of other hormonal reinforcing loops that would lead to your heart pumping faster/harder, i think, if you're substantially flexing it in a way that you typically do not.
