Changes in the mechanical properties of rat tail tendon during postnatal ontogenesis

摘要

The ultimate tensile strength, elasticity modulus and ultimate elongation of tail tendon in rats aged 1–18 months were measured with an Instron tensile apparatus. An increase in all these parameters was observed during the period of maturation, with a later levelling off of the tensile strength and the ultimate elongation. The value of the elasticity modulus attained a maximum during sexual maturation, and then decreased and stabilize
