How Bone Responds to Weight-Bearing Exercise - Wolff’s Law

Question 1

What is Wolff’s Law?

Answer 1

Wolff’s law is a principle stating that bone can increase its strength in response to stress (e.g. weight-bearing resistance exercise) by laying down more bone.

Question 2

Wolff’s Law of Bone Strengthening as a Result of Bone Remodeling (3 points)

Answer 2

1. Mechanical stress on bone, such as during a barbell squat, causes the bones to bend
2. At rest, bone osteoblasts
   migrate towards the area
   experiencing the greatest
   stress
3. More bone is laid down to
   reinforce the area under the
   greatest stress
