Yes it does starve the brain of oxygen and render can someone unconscious by oxygen deprevation and even kill if applied long enough. The Local Police Department has now doesn't allow chokeholds Maybe because some cops don't know what they are always doing and sometimes mistake seizures as resistence or maybe they just get a little too excited. Who know but I hate to see this policy.Originally posted by MikeWilliams
I didn't know that. Thanks Ed. So the pressure of the blood already in the head prevents fresh oxygenated blood reaching it? i.e. the choke does work by starving the brain of oxygen? (Just checking in case I misunderstood.)

But, some chokes can cause immedimate knock outs. We have one we call the Masa Masacre. Its named after the Judo teacher from Yokohama who taught it to us. We didn't know the real name of technique. But basically it is a leg assisted choke done when the opponent is on the ground face down semi-turtled or on his hand and knees. Once you get the grip for the choke you sutemi (sacrifice fall). The collar circle closes so hard and fast it can knock you out immediately. Our dojo went to a tournament once and I was watching a team mate compete and he got the choke on and sacked. The guy went out immediately but the ref didn't catch it at first because there is no tap when you go out immediately. Mark was pretty shook up he looked at me and said Ed I killed him. I told no you didn't he's fine, which he was he just need to wake back up. Judo players are pretty sturdy. The knock out in this case I think has to do with the atemi effect of the collar closing so hard and fast but I could be wrong.
