[Assess learners' ability to apply wearable-derived load metrics (e.g., GPS/power, heart rate, HRV, TRIMP, session-RPE, acute:chronic workload ratio) alongside periodization principles (macro/meso/microcycles, progressive overload, tapering, recovery, individualization) to create and adjust individualized injury-prevention and performance plans for elite endurance athletes. Tasks include interpreting longitudinal wearable data, estimating injury risk, choosing periodization strategies, prescribing modifications for fatigue/illness, and defining monitoring and decision rules.]
