the adaptation of bone to mechanical stress

Bone adapts to mechanical stress through a process called remodeling, where it detects changes in load or pressure. When you put stress on bones—like weight-bearing exercise or daily activity—the bone cells respond by increasing bone formation in areas experiencing strain. This makes bones stronger and denser over time, better able to withstand future stresses. Conversely, reduced activity causes bone loss because the body perceives less need for dense, strong bones. This natural adjustment helps bones maintain optimal strength relative to the forces they regularly encounter, ensuring skeletal health and stability.
