[A person asked me to list some of what I knew, in the most basic format that is easy to understand for a Westerner, here is what I sent them]
Yes I practice Chinese style boxing and internal arts like Taiji Chuan. Although I am still discovering things as I go along.
The recent post (Taiji Chuan Force Vectors) is my recent work, so it is based on my current level. Previous early work blog posts from years ago, keeps things simpler.
For the simple list of internal power principles
1. Gravity 100% conversion. Falling directly in line with the acceleration of gravity 9.8 m/s/s such as dropping a knee on a fallen target, directly down and below your center of gravity.
2. Gravity partial conversion. Example, falling on/across someone and breaking their arm/leg, like in football injuries.
3. Force reflection is where energy projected into the target does not affect the target, instead it chooses the path of least resistance which is going back into the attacker’s body. Examples are when you push or punch a wall. You get a lot more energy back than if you punched water. The proof of which substance takes most energy, can also be seen in the displacement value of how much distance the target object has moved. Thus if a fat kid runs into a small kid, and the small kid gets ejected across the hallway while the fat kid is just standing there, then we can say the energy mostly went into the small kid. If the fat kid ran into a wall and got bounced off, then the energy went back into the fat kid. If the fat kid ran into a judo ka and got hip thrown, then this is a combination of various energies. The judoka uses the incoming energy, makes it go into a circle, and then feeds it back into the target, using gravity as an assist.
The judoka uses the incoming energy, makes it go into a circle, and then feeds it back into the target, using gravity to assist. This is an example of a technique that fuses together multiple principles into one technique.
4. Muscle acceleration: Just like in bench press where your triceps do a lot of the work, punches use the muscles to accelerate the arm and thus acceleration times mass equals force. The higher the mass, the lower the acceleration for the same effort, but the more force the mass hits with. Number 1 above is merely using one’s entire body mass, with gravity accelerating it. Muscle acceleration is limited by the limitations of the skeleton and tendon structure.
5. Intent. Desire, emotion, state of mind, all is included. This is either the strongest or the weakest force, as it is behind the use of all other forces. Intent controls the human body, so a weak intent produces weak results. In order to apply maximum power, one must look right at a target and then go through the target. Thus people who tend to look away when slamming a bat unto a target, can’t apply 100%. In H2H fighting, people flinch a lot, protecting their eyes or face. When attacking, it’s important to see the target. When moving, it’s important to use peripheral vision.
If there is no Will, there is no Way. So long as there is a Will, there is a Way to solve a problem.
