The Claim
Female runners with high Female Athlete Triad risk exhibit a 2.9-fold higher incidence rate of cortical-rich bone stress injuries than those with low Female Athlete Triad risk, demonstrating that cortical bone is significantly affected by cumulative physiological stress.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Female runners at high risk for the Female Athlete Triad experience 2.9 times more bone injuries in the dense outer layer of bone compared to those at low risk, showing that this type of bone damage is directly linked to physiological stress.
See the scientific wording
Female runners with high Female Athlete Triad risk have a 2.9-fold higher incidence rate of cortical-rich bone stress injuries compared to those with low Triad risk, indicating that while trabecular bone is more vulnerable, cortical bone is also significantly affected by cumulative physiological stress.
When a female runner doesn't consume enough energy and her hormone levels drop, her bones stop making new tissue and start breaking down faster, especially in the dense outer layer of bone, making it more likely to crack under stress.
What the research says
1 studyFemale runners with signs of poor nutrition and hormonal problems were nearly three times more likely to get stress fractures in their shins — even though those bones are supposed to be strong. This shows that when the body is under stress from not eating enough or having irregular periods, even tough bones can break.
