Very interesting ! Thanks Cap. It is pretty much the starting point of this thread, actually, the point I always tried to make :
‘When composite cadaveric tissue (skin, for example) is stretched, it lengthens. Even if the tissue is not taken to the point of rupture, it will not return to its original length because it has undergone “creep.” Creep is a gradual but permanent lengthening of the tissue due of slippage of short collagen fibers.
Since human cadaveric tissue responds this way to the stress applied, one might assume the same type of stress (stretch) needs to be applied to living tissue to create permanent change. But living tissue undergoes microscopic tearing of the fibers and cells, resulting in inflammation and small hemorrhages which leads to fibrosis that limits tissue mobility even more.
Living tissue held at its easy elastic limit, however, will activate the collagen fibers to turnover in a way that modifies the cross-linking of the fibers, allowing greater length. There is no creep or inflammation but rather a response that can be called “growth.” Growth is unique to living tissue.’
We want growth, not creeped, scarred tissue. Furthermore:
‘…the element of time and the consistency of low stretch creates the tissue response of growth.’
CLINICAL SUGGESTIONS
…Clinical experience reveals that the first one or two casts usually brings about significant improvement but there is diminishing response to continued cast changes over time. When the time between cast changes is increased, a significant improvement in both range of motion and quality of motion is noted, even with the most stubborn joints.
….
Even uninjured tissues need a balance of movement and rest.’
(emphasis added).
This is consistent with both what succesful long time pumpers and even extenders manufacturers advice. This is why ‘fatigue’ as called by clamp-style hangers (whatever it means, since it always remained a vague word) should actually be avoided: if the tissue is fatigued, it won’t grow at optimal rate. This is why it is unlikely to get extraordinary gains hanging (or pumping, or stretching) all the day (and night? Come on….), 7 days per week for months or years.
