To me, I see available energy paths in the body to consist of muscle, bone, ligaments/tendons, and other parts of the fascia. The bone, muscle, and (to some extent) the ligament/tendon paths are mostly linear - the energy comes in and basically follows a straight path through to the destination. However, with fascia, there are multiple paths the energy can go at the same time and still reach the same destination.
I don't think fascia works quite this way ... what little contractile force the fascia does contribute perform is very slow and quite modest. The enervation and receptors (pressure, acceleration & relative position, etc) however 'alert' and perhaps participate in 'recruitment' of disparate muscles to become coordinated and share the load thereby minimizing the local effects while contributing to the 'connectedness' we are talking about.
The energy is not carried by the fascia so much as its 'character' is determined used as part of a feedback loop such that musculo-skeletal configurations can be adjusted to accomodate the load. Exactly how this control system operates (the algorithm if you will) is what is being conditioned by all the training. This is oversimplified but I think gets at the gist of it (my sense anyway).
