A choke hold, or stranglehold, is any type of unarmed strangulation technique used to submit an opponent or incapacitate a foe by restricting their airway (choking) or blood flow (strangulation). Choke holds are common in martial arts such as judo, Brazilian jiu-jitsu and sambo.
In judo these are known as shime-waza, and were originally codified by Kano Jigoro and the Kodokan judo school.
