What is bone Mass?
The scale estimates the weight of non-living bone mineral content . This is important
for monitoring and maintaining healthy bones through exercise and a calcium-rich diet .
An adult skeleton is made up of 206 bones, which come in several different shapes
and sizes and have specific structure . Your bones contain blood vessels, nerve cells
and living bone cells known as osteocytes . These are held together by a framework
of hard, non-living material containing calcium and phosphorous . A thin membrane
called the periosteum covers the surface of your bones .
Bone Mineral Content differs according to age and sex . For Adults: The average
bone mineral content of 15-29 year old female is approximately 6lb, that for
15-29 year old male is approximately between 6 and 7 . 7 5lb . (Rico et al . 1993)
For Children: The average bone mineral content of 8-16 year old child is
approximately between 1 . 7 and 4 . 8 5lb . (Faulkner et al . 1993)
