Re: Physical Tension - Another Thought

From, "The Intelligent Body" The Sutherland Cranial College

Dr Stephen Levin took this thinking one step further, maintaining that the body "is" a tensegrity structure, with tension provided by a matrix of connective tissues - ligaments, muscles, blood vessels, nerves and fascia (in sheets, making compartments), giving strength, integrity and pre-stress. Compression is provided by the bones and incompressible fluids in compartments. The bones act like spacers, providing the divergent forces needed to hold the spaces open. He sees the body as "A soft tissue entity, with local bony spacers, rather than a hard tissue entity with soft tissue motor units".

Muscles induce motion and help maintain the pre-stress which we call "tone". When muscles shorten, they also expand width-wise, which puts more tension on the fascial/tensional element, increasing stability. We can deliberately increase tone by contracting muscles, increasing pre-stress before lifting heavy objects. Water in its structured form contributes to tone. Enclosed in fascial compartments, it provides shock-absorption and resists deformation. The fact that joint facets cannot be forced into contact in live subjects is compatible with what we know about the properties of synovial fluid, alternating in state between sol and gel. Viscosity determines the rate at which fluid responds to motion demands and how it performs its role in the tensegrity matrix. Levin also maintains that ligaments act like rubber bands, their elastic rebound contributing to the "spring" in our joints, thus also acting as"movers", e.g. in the foot and knee when walking.

Roughly speaking, the strength from the ground goes through the bones (ki of Earth) and the "connective", "down-pulling" strength (ki of Heaven) goes through the fascia/ki arrangement (which is more complex than that simple statement implies).
