Stretching is thought to stimulate gel-like glycosaminoglycans (GAGs) that, with water and hyaluronic acid, lubricate connective tissue fibers and keep them from sticking and forming excessive cross-linkages.
Detail
Stretching is thought to stimulate the production and retention of gel-like substances called glycosaminoglycans (GAGs). The GAGs, along with water and hyaluronic acid, lubricate connective tissue fibers, maintaining a critical distance between them. This prevents the fibers from touching one another and sticking together. As a result, excessive cross-linkages are not formed.
This is the third of the three adaptations listed under What Happens When You Stretch.
Key facts
- GAGs (glycosaminoglycans) are gel-like substances whose production and retention stretching is thought to stimulate.
- GAGs + water + hyaluronic acid lubricate connective tissue fibers.
- The lubrication maintains a critical distance between fibers, preventing them from touching and sticking.
- Result: excessive cross-linkages are not formed.

- Semi-Permanent Fascial Sheath Length Change — the connective tissues whose fibers are kept lubricated.
