Guillotine choke
From Wikipedia, the free encyclopedia
The guillotine choke is a chokehold in martial arts applied from in front of the opponent. The choke involves using the arms to encircle the opponent's neck in a fashion similar to a guillotine. The technique is either a type of tracheal compression restraint that prevents air flow to the lungs, or a blood choke depending on how it is applied. When executed from the ground, the person applying it will try to control the opponent by the hips, for instance using a closed guard. This is done to prevent the opponent from escaping the hold, and to be able to apply additional pressure by extending the hips.
This technique can cause unconsciousness if done correctly. It is taught in various grappling martial arts, including Jujutsu, Brazilian Jiu-Jitsu, Judo , as well as in mixed martial arts competition.
