sports physical therapy tion between the number of bone strain cycles, strain magnitude, and the speed at which strain is introduced (strain rate). Once the threshold for microdamage has been surpassed, further increases in bone strain cycles, magnitude, and/or rate re- sult in additional damage. The damage is a natural and useful phenomenon, as it not only helps dissipate energy that may create a fracture but also serves as a stimulus for targeted remodeling (FIGURE 2B). Targeted remodeling refers........
