An Example Of HOW Kata is Science

February 17, 2020



This is an example, using a move out of Kusanku, of what we term neurological dysfunction.


Many call it a "knockout", but I feel that confuses and "blurs the line". Even though a common reaction to these, even when they result in unconsciousness, the person can and will break-fall. This is a natural body reaction. Slip on ice, your body will attempt to catch itself. Sometimes the person doesn't go out until they impact the ground. This is possibly due to the added impact over stimulates the nervous system. Some, like me, the impact brings me back. However, many critics will claim BS on a knockout because the person didn't go unconscious and may catch themselves, which in itself is not a valid argument because a TKO in boxing, mma, etc, often the person goes down, catches themselves and does not lose consciousness, yet can no longer function clearly.


I use the term neurological dysfunction as one can clearly see that my uke (person I am demoing on) loses control of his body, his legs come out, and for ample time I would need to finish, can not function... like a TKO in combat sports.


The science behind this move...when you cover the eyes, you disrupt what is known as the "righting reflex". This reflex is what helps our brain and body determine what is up, down, left, right etc. Take away the visual information to the brain and the bodies ability to maintain balance is compromised.


Next the strike to the side of the neck has several physiological components happening at once. First off, you are striking the Jugular Vein, possibly also the Carotid Artery. Secondly you are striking the Vagus Nerve. One of the functions of the Vagus Nerve is to monitor blood pressure. A blunt strike, quickly stopping blood flow to and from the brain, combined with a quick change in or loss of monitoring of blood pressure will cause a "survival" function in the body to protect itself.


Many of the "reactions" to kyushojitsu strikes are a protective response, built into the involuntary functions of the body. It is the body reacting to protect from further damage. Pain is a protective response. Your body pulls away to protect from damage or threat of further damage...


You also have the reaction of the muscle spindles within in the Sternocleidomastiod Muscle (SCM) which is another whole long discussion in itself...


So, a seemingly simple move, which many dismiss because it comes from kata, which many will call BS, is actually loaded with a CRAP ton of SCIENCE...imagine that...
