Why does rapid skeletal growth during adolescence increase the risk of stress fractures due to mineral deficiency?

💡 Explanation

Rapid skeletal growth increases the risk of stress fractures because the bone formation rate can outpace the rate of mineral deposition, leading to inadequate mineralization relative to the increased mechanical loading. Therefore, bone strength is compromised, rather than other factors such as osteoclast activity being directly responsible.
