i am guessing you want to make an animation with poser with such information, but have to say i think you are putting too much pre-thought into it. you need only search for mo-cap(motion capture) files to assist you with animating people or animal motion. if you go looking for the info you are after, i think you will spend a couple of days reading useless info, and still not be able to animate, so try googling "mo-cap" see what you can find, work with that for a bit, then look to refining details of motion, remember that camera movement can assist in the illusion of various types of movement also.
