Modesto, wow, great information! You’ve just added another 500 questions for me! Now I’m confused. It seems that there may be conflicting information on the toughness of scar tissue or maybe I’m just not understanding it correctly.
The site: - makes the statement:
"Many amputees have scar tissue in the affected limb associated with surgery or the original injury. Scar tissue is tougher, less elastic and often thicker than normal skin and muscle. Due to it’s restrictive characteristics, scar tissue can have a negative effect on adjacent tissue, resulting in stiffness and/or pain."
Not the first time I’ve heard this. But - on the other hand:
An article on healing at http://educatio n.vetmed.vt.edu … ab5/healing.htm , states:
Collagen remodeling will occur for some time afterward, up to several months,depending on how extensive the damage was. Regions of scarring become stronger over time, but they will never achieve the same strength as the original tissue. Tensile strength of 70 percent of normal is about the greatest one could expect.
Insight on this would be especially helpful. One would have to reason that if the resulting scar tissue was weaker than the original normal tissue, slowing gains would have to be attributed to another process at work. Could it be possible that the tissue surrounding the scar tissue increases in strength to somehow "compensate" for the weaker scar tissue? Otherwise, less force would be needed to damage this replacement tissue, meaning the workload for subsequent sessions would need to decrease or stay at the same level. In other words, the healed tissue will be either stronger or weaker. If in fact, it is stronger and we base our assumptions on scar tissue being weaker, what attributes to the new strength? I think we can safely say that the penis does adapt somehow to increasing stresses. Any thoughts on this?
Regarding scarring as a consequence of PE vs muscle building. It is my understanding that muscles rebuild very differently than soft tissue. I may be wrong, but most articles that I have read seem to indicated muscle is regenerated to some extent, not repaired. That there is actually new muscle cells formed and that the fiber bundles of muscles themselves enlarge. This would contrast with the soft tissue repair process in which the wound is actually filled in with ECM (extracellular matrix) material which consist of collagen and newly formed blood vessels. It seems that certain body parts (I.e. Bones, and the liver) have the ability to regenerate new cells but other organs or structures do not and the result is replacement by connective tissue (scarring.) As you said bone distraction produces new bone not scar tissue.
There does seem to be support that fibrosis is not a natural process but actually a malfunction in the body’s healing response. The site: , states the following;
Scarring is the body’s normal wound healing response in which specialized cells called fibroblasts deposit layers of collagen, a ubiquitous protein that helps form a scar. Sometimes the normal wound healing response goes awry, and the formation of scar tissue occurs faster than collagen is naturally broken down. The excessive production and deposition of collagen results in pathological scarring, a process called fibrosis
The question is what makes the process go "awry?" Over training doesn’t seem a likely candidate to me? Thoughts?
Modesto, thanks a bunch for the links and TL-Extract. I printed it out and will read it later. It seems the more I learn the less I know! Keep up the good work!! Thanks for your insightful response.
PS. How do you create links to other posts? I’ve search the help file unsuccessfully. Thanks!
