Explain how a carotid choke works.
Please explain to me how a carotid choke works. What is happening and why does it happen.Judo is only gentle for the guy on top.

The state of unconsciousness, according to the investigators of the Society for Scientific Study in Judo, Kodokan, is caused by a temporary hypoxic condition of the cerebral cortex.
Judoinfo has a huge post on this.

Personally I think that unconsciousness is a result of feinting due your body detecting a blood pressure differential. The same effect can be had from a perfect Thai kick to the neck. That only hits one side and is supposedly a disruption of the vagus nerve.

I didn't ask what judo info says I asked you as in the forum a specific question.
Sorry your second post was not up.
Good answer anyone else?Judo is only gentle for the guy on top.

It's not entirely clear what you're asking Josh.
The brain has two redundant arteries feeding it blood - the carotid arteries -- one on the left, one on the right. The brain needs a constant flow of oxygenated blood to work properly. Strangulations (blood chokes) close both of these arteries and cut off a sufficient flow of oxygenated blood. Held long enough, this will induce death from hypoxia.
It's also possible that a blood choke can induce a vasovagal reaction by manually stimulaing the vagus nerve. http://en.wikipedia.org/wiki/Vasovagal_response This can cause fainting through a complex feedback mechanism.

Blood flow too/from the head is restricted by pressure on the major arteries on either side of the neck. As the blood that is in the head becomes de-oxygenated and blood pressure increases the body attempts to improve blood flow and reduce that pressure by forcing the body to a prone position by turning off the lights, so to speak and making it easier for the heart to pump blood to the brain.
If you want the hard science I'll have to bring my wife in on it.

A choke is not defined as an air restriction just a restriction in general so without semantics explain how it works.Judo is only gentle for the guy on top.
