The research to date explored a combination of factors that may put high level athletes at risk for bone stress injuries (BSIs) such as dietary intake, menstrual disturbances, training volume, body composition, and biomechanical variables. The primary purpose of this study was to determine which risk factors play a role in BSIs in collegiate cross-country athletes. Two independent samples t-test assessed baseline bone quality and muscle quality measures between athletes with stress fracture history and those without. A multivariate logistic regression model assessed risk factors for incident BSI over the athlete’s competitive season. Athletes with stress fracture history had higher baseline bone mineral content and lower echo intensity values when compared to athletes without stress fracture history. Athletes with a lower bone mineral density (z-score -1.5 or below) were at a higher risk for incident BSI adjusting for stress fracture history, sex and leg lean mass.
