Rear naked choke

The word naked in this context suggests that, unlike other strangulation techniques found in jiujitsu/judo, this hold does not require the use of a keikogi ("gi") or training uniform.

[2] Recent studies have shown that the rear-naked choke takes an average of 8.9 seconds to render an opponent unconscious regardless of the grip that is used.

It digs the blade of the wrist into the carotid sinus similar to the hand clasp method and uses a lever motion helped by the underhand.

It is faster to apply requiring less strength than the figure four/mixed-martial arts version but is more difficult to learn.

Hadaka Jime is also recognized as Hadaka-Jime-San in Danzan Ryu jujitsu's twenty-five techniques in the Shimete list.

[9] Modern pro wrestling's first "sleeper hold", technically different from a choke, which is a compression of the throat and/or adam's apple, is thought to have been performed by Jim Londos on 29 June 1931.

Though Londos' original move may or may not have been inspired by judo's "hadaka jime", pro-wrestling's sleeper and a rear naked choke both share a similar style of execution.

However, in order for the sleeper to be used in the modern performance art-related world of pro-wrestling, the leverage arm is positioned in a relaxed state so the hold is not fully applied.

In modern catch wrestling circles, the term sleeper hold refers to a variation of the rear naked choke in which the individual performing the hold snakes the leverage arm across the opponent's throat (in the same manner as the traditional rear naked choke) and grasps their opposite shoulder, rather than the biceps.

The opposite hand is also placed against the base of the opponent's skull in the form of a closed Hammer Fist, or on top of the head.

Some common defenses include tucking the chin to prevent the choking arm from applying pressure to the neck.
