Greetings.
Notice that in this analysis the degrees of freedom that each joint has is taken into account.
On a small note: putting your "weight" (measure of force) into it is different that getting your mass (measure if inertia, can be used to calculate momentum... which is important to study collisions) behind something.
Another note: "heels out" gives a better "bracing angle" for the lower platform in the neutral bow and horse stances. Static structural analysis validates this assertion.
To measure "dynamic" sequences this way, you can use finite element analysis to make discrete approximations (very accurate approximations, by the way...) on the stages of the continuous flow of destructive sequencing.
kinesiological output would depend on the path taken by the body to get to the impact stage (there are optimal paths that generate maximal output),
...and the transfer of kinetic values to the attacker would depend on the stability of the anatomical structure at that point (which should be optimally stable to get most destructive effect).
Not maximally stable structure at impact means that the kinesiological output is dissipated on the joints and connective tissue, and in vector components that are not in the targets direction. Also, the body of the kenpoist would absorb and feel the effects of the strike and would have to move to adjust, decreasing protection, stability and control of the body.
I guess doing my thesis in mathematical physics all freaking day and applying it to what I do here has me a little jacked up on biomechanics...
Here's the thing.
The concepts of marriage of gravity, back up mass and torque (power generation principles) in their qualitative natures are NOT simply equivalent to body momentum in the vertical, forward horizontal and lateral horizontal axis.
To explain each quantifyably needs more than just momentum. Yet it is a start that we have quantifyable measures that can be used for comparison in each instance.
Hope this gets the creative juices flowing some more!
