← Human Body & HealthFollowing sustained isometric contraction, which process risks tendon damage?
A)Creep deformation increases tendon length✓
B)Increased proteoglycan matrix hydration stiffens tendon
C)Decreased collagen cross-linking reduces flexibility
D)Reduced tenocyte activity halts collagen synthesis
💡 Explanation
Sustained isometric contraction causes creep, where constant force leads to slow tendon elongation because of gradual sliding of collagen fibers. Therefore, creep deformation increases tendon length increasing, rather than alternative changes like hydration (B) or altered collagen structure (C,D).
