"In fact, in a muscle with a tighter reciprocal harnessing of the actin and myosin fibers and a thickening of the connective tissue that becomes fibrous, it results in an increase in the passive resistance force of this muscle, a decrease in the elastic capacity, a decreased resistance functional "
(U. Morelli).
Below is an empirical and simplistic but exemplary example of the above. (FIG.2)
These collagen and fibrous thickening are areas that need manipulative treatments to maintain physiological elasticity / flexibility, especially after a traumatic event or an intensive / repetitive work / training cycle aimed at a specific muscle-joint district.
In this regard, during the search for material to document and deepen the subject matter, my attention was captured by the vision of a dissection by the Department of Human Anatomy and Physiology of the University of Padua, where the musculature in form naked And bandaged, with the summary of the report "Anatomical study of myofascial continuity '
(C. and A. Stecco), presented at the First International Congress on Fascia Research, held in October 2007 at Harvard, Boston USA.
Later I was struck by the definition of myofascial expansions of the muscles, which are the object of study and research. The precious help had by Luigi Stecco, one of the first scholars and operators in the fascia field, to deepen the physiology and mechanisms inherent in the various forms of CT, gave me led to better understand and clarify the way in which the myofascial manipulations, as well as the technique passive, they act by improving a non-optimal physical-athletic state.
Thanks to Stecco, some considerations arose that in my humble opinion must absolutely be part of the scientific background of a sports bodyworker and be kept in mind during the myofascial work that is performed on an athlete.
When a fibrous CT is treated with the manipulation, or better still the densifications present in the myofascial expansions , the pressure exerted and the heat induced are capable of soften there Fundamental Substance of the fascia, which can then pass from a physical state of gelation ( gel ) to a more soluble state ( sol ) also allowing the rupture of any tissue adhesions. Collagen and elastin are often found together, and it is their interaction that gives rise to the viscoelastic properties of the connective tissue. The degree of viscoelasticity depends on the relative amounts of collagen, elastin and ground substance * (Ahluwalia arts).
* The gelatinous "fundamental substance" that contributes to constitute, together with Collagen and "Elastin, the" extracellular matrix "- MEC - both in" soft tissues "and in" hard mineralized "consists mainly of proteins PolySaccharides, or Glycos Amino Glycans (GAG), which serve as a cementing substance between the Collagen and Elastin fibers.
