Tendon relaxation

**Tendon relaxation** refers to the phenomenon whereby tendons, composed mostly of collagen, dissipate internal stress when held at a constant length. This biomechanical property, technically termed "stress relaxation", is a manifestation of tendon viscoelasticity—meaning tendons gradually lose force under sustained deformation[1][3][6]. This process is mediated by the complex hierarchical structure of the tendon, including proteoglycans and collagen fiber sliding[1]. While important for tendon function and injury recovery, "tendon relaxation" is not a molecular entity, receptor, or classical therapeutic target, but a mechanical behavior of tissue as a whole[2][4]. **Key context:** - Tendons are mainly composed of collagen, with roles in force transmission from muscle to bone[4]. - Viscoelastic properties (such as stress relaxation and creep) underlie the tendon’s response to load[1][6]. - Alterations in tendon relaxation properties can be relevant in diseases such as tendinopathy, but intervention strategies usually target the cellular or matrix components, not "tendon relaxation" itself[2][3]. **Summary:** "Tendon relaxation" is a process or property, not a drug target, enzyme, transporter, or receptor. If you are seeking information on molecules modulating tendon relaxation (such as enzymes involved in matrix remodeling or receptors mediating tendon cell responses), those should be specified individually.
