Re: Using ki-skills for "aiki" in Daito-Ryu
It is my current opinion, based on my experience, that the fascia is not fired on and off like muscle. Rather, it gets "turned on" and simply stays on at a relatively constant strength.
What the fascia does, IMO, is form a tensegrity structure. Once a tensegrity structure is established, the "structure" of the body will stay stabilized all by itself, more or less. In other words, the fascia will begin bearing the load of the body (or any incoming force).
At that point, muscle can be used to "guide" movement---but NOT bear load. (It's actually a bit more complicated, but that's the general idea.) So, when someone says they're "moving without muscle", they're saying their muscles aren't bearing any real load, not that they're not involved. Do you understand that distinction?
