Episode Summary
Discover how growth, bone maturity, biomechanics, sleep, stress, and recovery shape bone stress injury risk in young athletes. Learn which factors can’t be changed, which ones can, and how better screening can help prevent repeat injuries.
Intrinsic risk factors for bone stress injuries in young athletes are divided into non-modifiable and modifiable factors. Non-modifiable issues include growth spurts, skeletal immaturity, delayed menarche, sex, ethnicity, family predisposition, and possible inherited problems with vitamin D absorption. The transcript also reviews biomechanical features such as high arches, overpronation, leg length discrepancy, and foot alignment issues, while noting these often matter most when combined with increased training load or low energy availability.
Modifiable factors are presented as especially important. These include inadequate fitness for current demands, body composition, hormonal status, poor recovery habits, sleep quality, stress, and perfectionist or anxious traits that may drive excessive training. Early sport specialization, too many consecutive high-intensity days, and limited rest are highlighted as common contributors. Sleep is examined in detail, including the effects of blue light, disrupted circadian rhythm, and reduced bone formation. A previous stress fracture and family history further increase recurrence risk. Learners can expect practical guidance on assessing training, recovery, nutrition, sleep, and psychosocial factors when evaluating injury risk.
