This is not my normal fare, but I had to find out if it was possible to knock someone out using only a pressure point. I found my answer, and it’s ‘yes’.
In the video clip below, the instructor is demonstrating a four-step move that leaves the boy totally out of it. If you rewind the video to 04 seconds, you will see that the move which actually knocks him out is the third one. It pushes the point of the instructor’s elbow into a pressure point on the boy’s chest. You can hear an ‘oof’ sound as it happens.
The blow to the jaw is probably not needed, at least not against an opponent who isn’t actively fighting back.
I have to say this is one of the scariest things I’ve ever seen. Many of the people commenting on the video try to pass the whole thing off as a fake, but if you watch only the boy’s face, you’ll see that he would have to be an Oscar winning actor to fake this reaction.
Youtube is an amazing resource. :(
