Choking Techniques (Shime-Waza)

Shime-Waza (Choking Techniques) is one of the groups of Katamewaza (Grappling Techniques)

The execution of choke is in practice a subtle art because of the potential danger for the opponent. There are three fundamental manners for chokes: compression of the neck-veins which restricts the flow of blood and oxygen to the brain, compression of the trachea,and compression of the chest and the lungs which prevents breathing.
