Hadaka Jime, otherwise known as the rear-naked choke to those outside of Judo, is a standard “choke” which is applied when an individual blocks off the carotid arteries on the sides of the neck. Blood flow slows to the brain and the individual falls unconscious within approximately 5-10 seconds. Once the choke is released, blood flow resumes and the individual wakes up. In a proper carotid choke there is no pressure applied to the windpipe and thus there is no disruption in breathing. In Judo tournaments children as young as 16 are allowed to apply near full-tilt carotid chokes to the point of submission or unconsciousness. Kids in Brazilian Jiu Jitsu tournaments can apply chokes in the same manner as young as 6.
While Judo and Jiu Jitsu are by no definition tame, children and adults are allowed to use variations of carotid chokes regularly even to the point of unconsciousness without the body count one would associate with a deadly or fatal technique. Exceptions and accidents do exist but the numbers back up the relative safety of these moves. As such, the notion that any use of a chokehold is inherently deadly force is either a gross exaggeration or the result of misunderstanding the technique. In law enforcement, carotid chokes are known as “Vascular Restraints.” Continue reading
