Re: "Conventional Muscles" and Internal Power

What's the difference between a "conventional" muscle and whatever other type you're referring to?
Hi Walter-
I think this is an important question and lots of people think/guess about it. We don't currently have hard data so that's what we do for now -- think and guess. But there is a proposed answer that is rational. It has to do exactly with how you posed the question:

If they're skeletal muscles going from one bone across a joint to another bone,
That's the "if" in question. Have you read people here refer to terms like "local muscle" and "long muscle?" Of course neither are scientific terms but they are terms that deal with exactly what you described here.

The hypothesis:
Let's say there is only one type of muscle tissue involved, shared by IS and normal/conventional. What is different may be the connective tissue not the muscles. Connective tissue (such as the ECM of muscle, and that muscle's tendons) shows adaptive changes that are correlated to the load that they commonly experience, yes? Also, body-wide sheets of connective tissue (the same type of tissue as this adaptive connective tissue) are contiguous with muscles, tendons, and ligaments. So, it is theoretically possible for a practitioner to train some connective tissue functional connections that span many joints. Thus you can have "regular" muscle tissue pulling on "developed" connective tissue connections in a trained body, where these muscles would NOT as you put it be "going from one bone across a joint to another bone" -- rather, they (the trained novel muscle-connective tissue units) would be going from location to location across many joints. The implication is that a different kind of motor behavior would be possible, by use of these long-range connections that are trained to support high loads, across many joints (ie the length of the whole body).

If that seems too far-fetched, here is an example with a different type of connective tissue: bone. Say you partially outstetch your arm using conventional "local muscle." Now something touches your outstretched hand. You can extend your knee joint of your rear leg and thus apply force to the thing touching your hand. Or you can extend at the elbow and also push the object. 2 different muscles producing the force, vastly different in location relative to the atari. OK this is nothing special, of course we all know this. And it in itself isn't "IS." But it is an example of a possibility that can be explored more thoroughly than this mundane example.
