Episode Summary
Learn how bone stress injuries develop when training load outpaces an athlete’s capacity, and why preventing recurrence means asking what changed. Explore the key intrinsic and extrinsic risk factors—from fitness, nutrition, and fatigue to spikes in workload, surfaces, footwear, and technique.
Bone stress injury assessment is framed around intrinsic and extrinsic risk factors, with a strong emphasis on understanding why an injury occurred so recurrence can be prevented. Intrinsic factors relate to the athlete’s capacity, including modifiable issues such as strength, fitness, nutrition, and fatigue, alongside non-modifiable factors like sex, genetics, menstruation history, and growth or maturation.
A major focus is extrinsic risk, especially training load. Key contributors include low fitness, limited training history, sudden spikes in activity, repeated high-intensity sessions, back-to-back loading days, seasonal return to sport, and early sport specialization. The explanation highlights the balance between load and capacity, showing how injury often develops when demand exceeds what the athlete can currently tolerate.
Other important influences include training intensity, repetitive or monotonous practice, insufficient recovery between sessions, surface changes, footwear changes, technique, and sport-specific demands such as throwing or bowling mechanics. Nutritional status is presented as especially important for bone health. Learners can expect practical guidance on subjective assessment, identifying change over recent weeks, and building a clearer picture of the factors behind bone stress injuries.
