Myofascial System and Physical Exercise: A Narrative Review on Stiffening (Part II)
“Fascial Stiffness:
Stiffness, defined as the ability to resist deformation when subjected to mechanical stress, is a mechanical property of tissues [43,44]. Stiffer tissues deform less than softer tissues [13]. Several factors need to be considered, including stress, which is the stimulus applied to the tissue, and strain, which represents the resulting deformation from the applied stress. Additionally, biological tissues are viscoelastic, possessing both solid and liquid components [45] that cause them to deform less if stress is applied rapidly [45].”
