Why does excessive mechanical loading during intense weightlifting eventually lead to stress fractures in bone undergoing remodeling?

💡 Explanation

Stress fractures occur because, during bone remodeling, repeated high mechanical loads cause microdamage to accumulate within the bone matrix at a rate faster than osteoclasts and osteoblasts can repair it. Therefore, fractures develop, rather than bone strengthening, due to insufficient time for adaptive bone deposition.
