I am studying how stability affects the ability to perform movements. A physician friend of mine has noticed that certain critical kinetic chains (i.e. muscles that work together to perform movement) are needed both in small movements and in large ones requiring large force. After studying his arguments for a bit, I realized the basic idea he is describing is the same principle I have seen in martial arts texts. Specifically, from what I understand, the power one generates in a given martial arts maneuver depends greatly on how efficiently you use the body to exert the force it generates. In other words, you need to essentially use proper body positioning in order to concentrate all the force you are generating into the output. Physicists define power as work / time. I would like to say using a similar idea that martial arts is about maximizing work / energy. You in essence want to exert the most force possible on your target while using the least amount of energy possible.
What I Need:
I would like a martial arts resource that takes these factors into account. I want something that not only describes positions but explains why the combination of muscles or positioning of limbs in question is ideal for generating the particularly maneuvers described. I own The Anatomy of Martial Arts and this book is not sufficient. It is an anatomy book that has very little explanation of why particular groups of muscles are so good at generating force. It also doesn't offer expected limits as to how much force a given move can generate. So, as I say, I want something with a little more advanced descriptions. It doesn't necessarily need to involve physics explicitly. It could contain qualitative analysis (i.e. deltoid stabilizes the scapula and this permits such and such which results in much greater force).
Note, I am not seeking to learn martial arts, so any "how to" discussions are irrelevant. I care only about the stuff I mention above.
What resource should I consult? Please include some info about the resource so I have some sense of how well it satisfies the description I gave.
