As with other jointlocks, leglocks are more effective with full body
In training or sparring, leglocks are applied in a slow and controlled manner, and are often not hyperextended such as in the case of the comparatively dangerous
Some examples of the many types of leglocks are found below.
Kneebar
A kneebar (also known as legbar, kneelock or hiza-juji-gatame) is a leglock that can hyperextend the knee. The basic kneebar technique is similar to that of an armbar. The practitioner will trap the opponent's leg in between their legs and secure the leg with their arms so the opponent's kneecap points towards the body. The practitioner then applies pressure with their hips, forcing the opponent's leg to straighten, hyperextending the knee joint. A variation of the kneebar is similarly accomplished, but instead of holding the leg with the hands, the practitioner will trap the opponent's foot behind one armpit. The practitioner will then apply pressure using their upper body as well and their hips, yielding a greater amount of force applied to the knee, therefore rendering the lock much more difficult to escape before tissue or ligament damage occurs.
Ankle lock
An ankle lock (occasionally referred to as a shin lock) is a leglock that is applied to any of the
Straight ankle lock
The straight ankle lock (depending on how it is performed is known in judo as an akiresuken-gatame or ashi-hishigi) is what is usually thought of as an ankle lock. It is typically performed using the legs to isolate one of the opponent's legs, and placing the opponent's foot in the armpit, while holding the foot with the
Toe hold
A toe hold (also known as ashi-dori-garami in judo) involves using the hands to hyperextend and/or hyperrotate the ankle, typically by grabbing the foot near the toes, and twisting or pushing the foot while controlling the opponent's leg.[9] A common type of toe hold is the figure-four toe hold, where a figure-four hold is used to hold the opponent's foot. This type of toe hold is performed by holding the foot by the toes with one hand, and putting the other hand under the opponent's achilles tendon, and grabbing the wrist. By controlling the opponent's body, and using the hands to plantar flex the foot either straight or slightly sideways, hence putting considerable torque on the ankle. The toe hold can also be applied in a similar position as an ankle lock.
Heel hook
A heel hook is a leg lock affecting multiple joints, and is applied by transversely twisting the foot either medially or laterally.[10] The torsional force puts severe torque on the ankle, which in turn transfers torque to the knee.
There are several variations of heel hooks, with the most typical being performed by placing the legs around a leg of an opponent, and holding the opponent's foot in the armpit on the same side. The legs are used to control the movement of the opponent's body while the opponent's foot is twisted by holding the heel with the forearm, and using the whole body to generate a twisting motion, hence creating severe medial torque on the ankle. A similar heel hook can be performed by holding the opponent's foot in the opposite armpit, and twisting it laterally; a move which is referred to as an inverted, reverse or inside heel hook.
Many practitioners considered the heel hook to be a dangerous leg lock, with a high rate of injury,
Calf crush
A calf crush or calf slicer (also known as calf cutter, knee slicer, or knee separator), known in judo as hiza-hishigi, is a technique wherein one compresses their opponent's leg (heel to butt) while placing one's forearm or shin behind the knee to crush the calf muscle while potentially separating the knee joint. As with biceps slicers, there is a common misconception that this technique causes only pain. Calf locks can cause very serious injuries to the knee as well as damaging the calf muscle, and caution should be a priority when finishing the lock.
