I am probably going to go off on several different tangents, so bear with me. Also, I will not be able to remember everything I wish to say, so I will amend this post by adding as I think of stuff. I am one of those who, if I do not write something down or type it, it is gone. At least for a while.
Look at the facts:
1) Generally in nature, when something is repaired, the repair is stronger than the surrounding tissues. This is true whether it is a cut in a tree, a scar, a broken bone. Whatever. So, as these fibrous, collagenous tissues heal, they probably do become somewhat stronger.
2) The first limiting factors to be overcome are the shortest fibers. Then comes the next to the shortest etc.
3) After the shortest fibers fail, they are no longer the limiting factors. The next shortest are.
4) The first fibers to fail will be healing while the next limiting factors are being stressed.
5) After the first fibers are healed completely, they join with the current limiting factors. Therefore, as time goes on, more and more fibers are taking the stress at the same time.
Ex. Say you start hanging 5 lbs. Then assume the first limiting factors are ten fibers of equal strength, and approximate length. The stress on each fiber during the first set is somewhere between 5 pounds and one half pound. If the fibers are in descending strengths, each one will get the full five pounds of stress as the previous fiber fails.
At a later time, after the ten fibers have healed, another set is begun with five pounds again. Of the previous ten fibers, five are limiting factors during this set. Plus there is an additional ten fibers of the same length. So now the stresses are divided between the fifteen fibers, rather than ten. So the stress applied will be somewhere between five pounds and one-third pound per fiber, depending upon their length and strength.
This goes on set after set. Soon, you are dealing with a bundle of similar fibers as the limiting factors, equally dividing the stress among them. Plateaus? You bet.
6) The more stress applied at any one time, the more limiting factors will be broken through.
Ex. Say you hang ten pounds during a twenty minute set. You will break through all the one-pound, two pound, three pound limiting factors. Maybe the fours and fives. You will not break through any tens unless there is only one.
If you hang twenty, you will break through the ones through tens, maybe up to the twelve’s. But not the twenty unless there is only one.
7) You may have short fibers with high relative stress loads, and longer fibers with low relative stress loads. As the tougher, shorter fibers fail; the next fibers may be easier and require less stress to fail.
8) If you have a set of limiting factors, each with a five pound stress load. Then you have many longer fibers behind those (slightly longer) with only a one pound stress load each (defect), when the last of the five pound LFs give way, you will get a tear or rip as all the one pounders fail at the same time.
9) The body gives signals when the healing process has begun. It is called soreness. For the most part, when the soreness has ended, the healing has ended also.
10) Pain is an indication of severe tissue failure.
11) The amount of stress required to continue a stretch upon failed tissue is not as great as the amount of stress required to cause the failure. See #7 above.
Enough for now. Will add to later. Anybody getting a picture?
