When exercise does not increase bone mass, it has been observed that the risk of bone fractures increases due to osteoporosis.
<h3>What are the benefits of exercise to bone mass and density?</h3>
Bone mass refers to the mass of the bones in a living organism as a result of the deposition of minerals within the bone.
An increase in bone mass is directly related to the strength of the bone.
Strong bones have high bone masses whereas weak bone have low bone mass.
Physical activity have been shown to improve bone mass by increase the mass of deposited minerals in the bone.
Exercise such as walking, running, jogging, and other forms of exercise have been shown to improve bone mass and hence, the strength of bones.
However, when exercise does not increase bone mass, osteoporosis is observed which results in bone fracture.
In conclusion, the strength of a bone is directly related to the bone mass which is directly related to the mass of minerals deposited within them.
