I presume you mean by “fascial training” increasing its ability to resist tensile forces. To think you can separate fascia from muscle and bone and treat them as different structures denies the fact that muscle and bone arise within the interstices of the continuous fascial fabric, (Harris, A K, D Stopak, and P Wild. "Fibroblast Traction As a Mechanism for Collagen Morphogenesis." Nature 290, no. 5803 (1981): 249-51.), and are part and parcel of each other. All muscle contractile cells are imbedded within fascia and are the tensors of fascia. Fascia is a continuum with areas that may be more or less dense, but it is all one fabric. Pulling on a rope requires a counterforce and tensing fascia requires a counterforce. It is impossible to contract only one muscle, it is impossible to contract a muscle without increasing tension in the fascia, it is impossible to increase tension in muscle and fascia without increasing compression in bone. Fascia is totally integrated into the locomotor system and “fascial fitness” can only be accomplished by training the locomotor system as a functional whole. Fascia, muscle and bone is a trinity that cannot be functionally separated, they are one.

Dear Peter,

The fascial systems continuity in the body has been thought of as a tensegrity system. This concept has been integrated into functional exercises by so called Fascial Training systems. See the work of Tom Myers with Anatomy Trains.

Rather than specific training of the fascial system , training the body to work as "functional whole" requires the fascial system to perform its proper role and function.

I apologise, I see you have extensive literature on this already in your project log, I am very interested to follow it as my own work is in a similar field, but approaching it from a manual therapist perspective using indirect techniques. I wonder if there is a significant nervous system involvement in fascia stiffening that preceeds efficient transmission of forces. Some sort of on/off switch?

Maybe this is what you are looking for.
