Greetings.
Many principles and concepts that are used to teach martial artists tend to be qualitative in nature. For example, how can you describe "marriage of Gravity", "Back up mass" and "torque" as power principle?
Yet I can QUANTIFY body momentum, angular momentum, linear momentum of the weapon used, kinetic energy generated, kinetic energy transferred, momentum transfer, torque (NOT the same as the power principle!!!) and many more...
and how each can be measured in KMS (kilogram, meter, second) units or compare results subjectively through experimentation and output comparisons.
Marriage of gravity is more than just body momentum on a downward vertical axis. We're not just a nail.
Our bodies have a interconnected and complex dynamic structure that can be solidified and desolidified to allow movement or stability.
Since it is completely connected by constraints in the individual boundaries of the joints, movement in one part has an effect somewhere else...
sometimes it is NOT visible, since there might not even be movement, yet tensions and forces in the structure change...
and the body has to compensate to keep static equilibrium or move to achieve stable positioning.
Anyway, to measure movements with accuracy as to get the kinesiological output (the body's position, velocity, acceleration and mass in relation to an inertial frame and itself) is not that hard, and training to increase these measurable quantities seems as a great way to gauge training effectiveness.
Obviously, for applications timing and sequencing is important, yet finding the ways to maximize your output following the rules and constraints set up by your body and biomechanics (not by a ?style? or ?way?) in a way that takes into account the operational concerns of Combat should be considered.
Some may say that if that were the case, then we should use the mechanics of breaking a ton of bricks... yet that would violate one of the operational concerns of Combat: Keeping control of your body at all times. (Competition Breaking movements are completely committed and after the strike, most structure and control of the body is lost... the body must send all resources to stabilize the body... no protection.)
Enough for now... if anyone has a question of what I wrote or needs clarification, feel free to ask...
Enjoy!
