Ep 379: Bone Stress Injuries: Risk Factors, Diagnosis & Prevention (Part 2)

Bone stress injuries in athletes stem from a complex interplay between training load and biological factors, rather than simple overtraining. Beyond physical stress, critical risk factors include early sports specialization, underlying medical conditions, and, most significantly, low energy availability. Athletes training over 12 hours weekly face heightened risks, with indicators such as gastrointestinal distress, mood changes, and reproductive dysfunction—specifically menstrual irregularities in females and reduced morning erectile function in males—serving as vital clinical red flags. Clinicians must distinguish between high-risk sites, like the femoral neck and navicular, and lower-risk areas, utilizing targeted palpation and hop testing to guide diagnosis. Ultimately, preventing these injuries requires prioritizing adequate caloric intake, with a focus on fueling for biological health rather than pursuing extreme leanness, as even minor daily energy deficits accumulate into significant long-term performance and skeletal risks.
