Most Judo chokes work the corotid artery though, not the windpipe.

Not true grasshoper! Ed

Um, Ed, are you talking to me? If you are, please explain. The majority of the Judo chokes I have learned have had a major focus on the corotid as opposed to the windpipe...I'm not sayng all, but most. The majority of the ones I train utilize pressure on one or both sides of the neck, not the throat.

I would agree that the vast majority of chokse are corotid (blood) chokes either using the gi sleeves, lapel or the arms themselves. Many chokes CAN be easily made into trachea chokes but the more efficient ones are performed by closing off the blood supply to the brain.

These aren't dangerous is released quickly.

grasshopper, the basic hadaka-jime has many variations including the use of the knee to choke.Guilotine choke,variations of tsukiomi-jime and sode-garuma-jime to name a few. Ed

Would the bottom 3 articles on this page be of any use?

I think at least one of them has a contact email for the author so you may be able to discuss references etc.

Ed, you have a point, but considering this is a Judo forum I was imagining that the question was referring to Judo chokes as they are most widely practiced. The Guilotene (sp) choke is more widely a BJJ choke and is illegal in Judo competition. Everything has variations, but I was adressing the question from strictly a Judo point of view and how the techniques are most widely practiced in Judo clubs/competition. Obviously, variation could be made, thus making a choke more dangerous and putting other emphasis on it. I'm not disagreeing, you are correct in that the variations may put emphasis on the windpipe, but as I have seen them practiced in my club/other clubs/seminars/competitions, the main focus is on the corotid.

The thing is, judo is a competitive sport. The person you are trying to choke is going to do everything in his or her power to stop you, and the trachea is only an inch or two from the target area for the strangle-- so accidents happen, both the "I missed my target by a bit because he turned his head" type and the "there, that ought to slow you down a bit" type.

A light blow on the trachea can disrupt the phrenic nerve and cause a person's diaphragm to spasm, with an effect similar to having the wind knocked out of you. Of course, I can't see why anyone would *cheat* in a judo match. [IMG]http://www.fightingarts.com/forums/ubb/smile.gif[/IMG]

In self defense situations, brushing (or striking, if it's there) the trachea on the way into the strangle can really help things along nicely.
