KINE 2P84 Growth and Development
Width
- Periosteal surface: formation (outside surface)
- Endosteal surface: resorption (inside surface)
Modelling and Remodelling
- Epiphysis, growth plate, metaphysis, and diaphysis
Bone Mass and Growth
- Birth: ~100g ~3%
- Adult Male: ~4kg ~6-7%
- Adult Female: ~2.8kg ~6-7%
Calcium Content in bone
- Birth 25g
- Adulthood 1kg or 1000g
- Old age 600g
The higher the amount of exercise bouts/d the greater the bone strength- independent of
volume
