Assess advanced understanding of how biomechanical factors (gait mechanics, joint loading, muscle-tendon dynamics), training-load variables (volume, intensity, acute:chronic workload ratio, recovery), and nutritional contributors (energy availability, macronutrient composition, hydration, key micronutrients) interact to cause lower-limb overuse injuries in distance runners; quiz tasks include analysis of case vignettes, interpretation of gait/kinetic data, calculation and critique of load metrics, identification of modifiable risk factors, and design of evidence-based prevention and rehabilitation strategies.
