If a patient with osteoporosis begins a high-impact exercise regimen without medical supervision, which risk increases as bone remodeling responds to the increased stress?

💡 Explanation

Stress fractures become more likely because the initial remodeling response to high-impact exercise in osteoporosis involves increased bone resorption by osteoclasts to remove damaged bone before new bone can be formed by osteoblasts. Therefore, the bone is temporarily weakened, rather than immediately strengthened, and prone to fracture under high stress.
