The Claim
Female runners with high Female Athlete Triad risk exhibit a 4.4-fold higher incidence rate of trabecular-rich bone stress injuries than those with low Female Athlete Triad risk, due to the cumulative burden of energy deficiency, menstrual disruption, and low bone density.
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 with low energy availability, irregular menstrual cycles, and low bone density have a 4.4 times higher rate of certain bone stress injuries than those without these conditions.
See the scientific wording
Female runners with high Female Athlete Triad risk have a 4.4-fold higher incidence rate of trabecular-rich bone stress injuries compared to those with low Triad risk, indicating that the cumulative burden of energy deficiency, menstrual disruption, and low bone density substantially elevates vulnerability to this specific injury pattern.
When the body doesn't get enough energy, it stops making estrogen, which causes bones to lose density and become weak, especially in the sponge-like parts of bones. This makes those bones much more likely to crack under stress from running.
What the research says
1 studyFemale runners who have poor nutrition, irregular periods, and weak bones are over four times more likely to get stress fractures in sponge-like bones like the hip and spine, and this study proved it by tracking runners over years.
