A slowly applied stretch is less likely to increase tensile stresses on connective tissues.

A slowly applied stretch is less likely to increase tensile stresses on connective tissues.

• A. False
• B. It depends on rate
• C. Not enough evidence
• D. True

Answer: (D)

Connective tissues are viscoelastic, meaning their response depends on how quickly you apply a stretch. When you stretch rapidly, the tissue behaves stiffer and can generate higher tensile forces for the same amount of elongation. Slower, controlled loading allows the tissue to deform more gradually, distributing the load over time and often taking advantage of creep, where tissue length increases under sustained, low stress. This combination leads to lower peak tensile stresses during a slow stretch and reduces the risk of microdamage. So, a slowly applied stretch is less likely to spike tensile stresses, making this statement true.
