What effect is associated with vigorous heating?

• A. Reduces collagen elongation
• B. Facilitates stretching of collagen, affects viscoelastic properties
• C. Increases tendon stiffness
• D. Decreases tissue elasticity

Answer: (B)

Vigorous heating raises tissue temperature, making collagen more pliable and changing how the tissue behaves under load. As collagen heats, the bonds within the fibers loosen a bit and the tissue’s viscosity decreases, allowing more elongation and creep when stretched. So, heating facilitates stretching of collagen and alters the tissue’s viscoelastic properties. The other described outcomes—less elongation, increased stiffness, or decreased elasticity—contrast with the softened, more extensible state produced by heating.
