There has been much written in this blog on fascia / connective tissue - be prepared for even more!
Meeting up with the Fascial Fitness group in Munich last weekend really fired my imagination, and from the correspondence also those from across Germany too!
The Research Group has just showed that the water content of fascial tissues (usually around 68%) decreases during tensional loading and that this fluid extrusion is associated with a decrease of tissue stiffness (i.e. the so called ‘tissue creep’). This is revealed in a new paper just published.
During a subsequent resting period new water is soaked up again by the tissue and the fascia regains its initial mechanical resilience. Possibly similar changes in fascial properties may happen during yoga stretches, sport/exercise induced tissue strain, or in some of the fascia oriented manual therapies.
Interestingly, when the tensional loading is strong enough and the subsequent resting period long enough, then a ‘supercompensation’ can be observed, in which a temporary hydration increase occurs as well as stiffness increase beyond the initial values.
The authors speculates that similar temporary ‘strain hardening’ effects may play a role during some sports activities as well as in occupational medicine.
Strain hardening of fascia: Static stretching of dense fibrous connective tissues can induce a temporary stiffness increase accompanied by enhanced matrix hydration.
