I have recently had a few questioned asked about the Kyusho Jitsu Power Principle and therefore today I will address this. This is a principle that is really not talked about very often. However in the changing face of the martial arts world today it is a good idea to discuss this.
The Kyusho Jitsu Power Principle is based on 3 different parts. They are as follows.
- 1Mass
- 2Torque
- 3Marriage of Gravity
Kyusho Jitsu Power Principle - Mass
The first of the principles is "mass." I think it is fairly obvious we are talking about body and muscle weight. Now the first thing I have to say about all of the principles is that the "working aspects" are greatly over simplified! Going into the details I will today will help you with proper training!
When we look at mass you will find it is variable. Mass in motion has more effect than mass at rest. This involves different laws of Physics. The first being the Law of Inertia and the second Newton's Law of Motion.
Kyusho Jitsu Power Principle Law of Inertia:
The tendency of an object in motion to remain in motion and the tendency of an object at rest to remain at rest unless acted upon by an external force.
Kyusho Jitsu Power Principle Law of Motion:
"Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration."
This is written in mathematical form as F = ma
Therefore as I am sure you can see that the more body weight the greater the force or power. However force can also be increased by increasing acceleration speed.
Today there is an incorrect though process about "Bulking Up" to increase power. Mathematically it is correct, however in application it tends not to work very well. Why is this?
There are several reasons! The first is the more mass the more difficult to overcome inertia! And the second is the extra body mass has a directly negative affect on principle 2, which is "torque." Now people will argue that is shows more power on the "blunt" striking force tests, and this is true. But this is a "static" test and does not translate well to motion.
Therefore an increase in mass will impact torque and as a result reduce acceleration.
Kyusho Jitsu Power Principle - Torque
Movement in the human body is control by the muscular systems, that uses the spine as a pivoting point.
Without the spine being able to move the way it does motions like walking and reaching would not happen.
If any part of the system is impaired, then motion also becomes very restricted. This is a 2 part control system, as we look at motion from the hips, and also at the shoulder area.
The systems of the body in a healthy person are in perfect balance. Power training in excess, and done without regard to this "balance" while providing an increase in mass and therefore an increase in static power will restrict torque. This makes the power increase very inefficient!
Is inefficiency important? Yes because of energy loss! The harder movement is the more power is wasted and not applied. This is often referred to as "muscle bound."
The goal of the martial artist must be efficiency of movement. This is the true formula to creating power.
Kyusho Jitsu Power Principle - Gravity
This is a rather simple part, however it has generated a lot of questions. First I do not like the word "gravity" as it is overused and has never been proven. it is a theory which is fine. We are accepting observation as law, which is not the correct method of doing things. And most physicists are happy to admit this.
What we observe in life with objects falling is actually the law of density and buoyancy. This is why object fall to the ground and at what speeds they fall. There are many factors at play here. [a balloon is lighter than air therefore more buoyant]
For the purpose of a martial artist creating power is based on the idea that since our mass is denser than the air we move in, we will create more power moving in a downward arch versus and upward arch.
Upward motion require we overcome the inertia of our mass, while downward motion we do not need to overcome our mass because we are denser than air.
Now really the terminology does not matter. You can certainly call it gravity if you wish. I just personally prefer using "laws" versus "theory" whenever possible. Do you see the importance of the Kyusho Jitsu Power Principle?
Kyusho Jitsu Power Principle in Conclusion
In conclusion this is basis of power generation for not just the Kyusho Jitsu student, but any martial artist.
Today when we focus on power we are missing an important part of the equation.
This is also how a person of smaller size can overcome a larger opponent! And idea lost in today's competitive martial art environment. Thank you for taking time to read this article on the Kyusho Jitsu Power Principle.
