Most people associate the exerciseswith muscle building. Is there a Wolff's law for connective tissue? [2][3] The "stretch-hypertrophy rule" of that model states: "Intermittent stretch causes collagenous tissues to hypertrophy until the resulting increase in strength reduces elongation in tension to some minimum level".

Further evidence and confirmation of Wolff's Law of Bone Transformation. Its earliest known appearance is in John Joseph Nutt's 1913 book Diseases and Deformities of the Foot, where Nutt outlines the law by quoting a passage from Davis's 1867 book, Conservative Surgery: "Ligaments, or any soft tissue, when put under even a moderate degree of tension, if that tension is unremitting, will elongate by the addition of new material; on the contrary, when ligaments, or rather soft tissues, remain uninterruptedly in a loose or lax state, they will gradually shorten, as the effete material is removed, until they come to maintain the same relation to the bony structures with which they are united that they did before their shortening.

[1], It is also an application of the Mechanostat model of Harold Frost which was originally developed to describe the adaptational response of bones; however as outlined by Harold Frost himself it also applies to fibrous collagenous connective tissues, such as ligaments, tendons and fascia. Public Health Rep. 1989;104 Suppl:54-8. Conversely, tendons that have lost their original strength due to extended periods of inactivity can regain most of their mechanical properties through gradual re-loading of the tendon,[12] due to the tendon's response to mechanical loading. [11] Davis' Law Tissues will be shaped based on the stresses placed upon them. 2013;6:205-14. doi:10.2147/JMDH.S31659, Prabhat V, Vargaonkar GS, Mallojwar SR, Kumar R.

[4] Similar to the behavior of bony tissues this adaptational response occurs only if the mechanical strain exceeds a certain threshold value. Science. This was first noticed by Julius Wolff in the 19th Century, who got the naming rights. Wolff (1836-1902) proposed that changes in the form and function of bones, or changes in function alone, are followed by changes in the internal structure and shape of the bone in accordance with mathematical laws. One important rule to follow during your rehab is Wolff's Law: bones grow and remodel in response to the stress you put on them.

[2] [3] The "stretch-hypertrophy rule" of that model states: "Intermittent stretch causes collagenous tissues to hypertrophy until the resulting increase in strength reduces elongation in tension to some minimum level".
