I think there was some hubbub years ago after a number of black men died because of police choke holds, and there was a suggestion that black people may have a unique vulnerability to such holds. I never saw any clinical rationale, though.
Yeah, and the wrestler probably put him in just such a hold, not a “headlock”. I don’t know a wrestler worth his salt who would EVER use a headlock. First, it’s clumsy, ineffective....oh, and illegal in wrestling. It also leaves one HIGHLY vulnerable; your “victim’s” arms and legs are completely free to wail on you....or in wrestling, even if it was legal, the guy would simply pick you up and slam you down as you try to hold onto his neck/head. Stupid.
No, this guy, rightfully so, I guarantee you put him in a proper choke from behind: one arm across the throat, that hand grasping his other bicep; the other arm....hand to the back of the head pushing forward....all the while flexing the bicep of the arm across the throat.
The result is a devastating “scissoring” type action that will incapacitate ANYone (and a personal favorite, I must admit). Takes practice, but a wrestler can get behind you in the blink of an eye and engage that hold....and it’s all over.
It’s pretty clear from watching choke holds applied in MMA that unconsciousness can come very, very quickly.
More surprising is how difficult to tell if someone is out. It looks tough enough just for an experienced referee, for the person applying the hold, it must be almost impossible to be sure.
