Bone and Muscle Changes with Age: Understanding Density & Strength Loss
Bones
* Bone density decreases. This is due to a decrease in the production of osteoblasts, the cells that build new bone.
* Bones become more porous. This is due to a decrease in the production of collagen, the protein that gives bone its strength.
* Bones are more likely to fracture. This is due to a decrease in bone density and strength.
Muscles
* Muscle mass decreases. This is due to a decrease in the production of myocytes, the cells that make up muscle.
* Muscles become weaker. This is due to a decrease in muscle mass.
* Muscles are more likely to atrophy. This is due to a decrease in muscle use.
These changes in bones and muscles can lead to a number of problems, including:
* Increased risk of falls. This is due to decreased bone density and muscle strength.
* Muscle pain and stiffness. This is due to decreased muscle mass and flexibility.
* Reduced mobility. This is due to decreased muscle strength and flexibility.
* Increased risk of fractures. This is due to decreased bone density and strength.
