Book excerpt: Background: Up to 70% of runners experience a running-related injury (RRI) annually and recovery can take several weeks, resulting in a significant impact on a runner's ability to train and compete. Presently, the only agreed upon risk factor for RRI is having a prior RRI, and many runners sustain an RRI early in their running careers, potentially increasing their RRI risk indefinitely thereafter. Given the increase in cross country participation among younger runners, identification of modifiable risk factors among both high school and collegiate runners is critical for maintaining their health into and through college and adulthood.Purpose: This dissertation assessed training habits and psychosocial measures as potential risk factors for RRI among high school cross country runners as well as running biomechanics and body composition characteristics as risk factors for bone stress injuries (BSI) and Achilles tendinopathy in collegiate cross country runners. Methods: A prospective cohort study design was used, with one cohort of high school cross country runners (N = 434, ages: 13-19, grades: 9-12) from 24 high schools and one longitudinal cohort of collegiate cross country runners (N = 106) over 6 seasons from a single institution. High school runners reported daily sleep duration and quality; ratings of stress and fatigue; running volume, duration, and intensity; and RRI incidence. Among the collegiate runners, 3-dimensional running biomechanics and body composition measures were obtained at pre-season, and BSI and Achilles tendinopathy incidence were monitored throughout the year. Results: Among high school cross country runners, total weekly running volume and duration (p-values ≥ 0.64) and weekly changes in running volume, duration, and intensity (p-values ≥ 0.54) were not prospectively associated with RRI. Weekly changes in sleep duration, sleep quality, and fatigue were also not associated with RRI (p-values ≥ 0.41). There was a significant interaction between sex and changes in stress with RRI, with females demonstrating increased odds of RRI with greater changes in stress (Odds ratio [OR] (95% confidence interval) = 1.37 (0.97, 1.94), p = 0.07), while the opposite was observed in males (OR = 0.61 (0.37, 1.02), p = 0.06). Among collegiate cross country runners, the optimal model for determining BSI risk included vertical center-of-mass (COM) displacement (Risk ratio (RR): 1.14 (1.01, 1.29), p = 0.04) and bone mineral density z-score (RR: 0.83 (0.72, 0.95), p
