A long-distance runner increases their training volume rapidly. Which risk increases as bone strain increases in the tibia during this rapid adaptation?

💡 Explanation

Increased bone strain without sufficient rest can lead to microdamage accumulation. The bone remodeling process attempts to repair this damage, but rapid increases in strain can overwhelm the capacity of remodeling, leading to a stress fracture because the rate of damage exceeds the rate of repair. Therefore, stress fractures become more likely due to accumulated microdamage, rather than solely affecting osteoblast differentiation.
