Assess students' ability to design a 12-week, evidence-based, periodized training, nutrition, and injury-prevention return-to-play program for a high-school competitive soccer midfielder recovering from a Grade 2 hamstring strain. The task should require specification of phase-by-phase objectives (rehab, strength, power, sport-specific conditioning), measurable performance targets (e.g., strength LSI, 10–30 m sprint times, CMJ, Yo-Yo/fitness test thresholds), clear progression criteria and load-management rules, nutrition prescriptions for growth and performance (energy, protein, carbs, hydration, micronutrients), and practical monitoring strategies (pain/VAS, session-RPE, training load, strength/symmetry tests, compliance). Include safety/clearance decision points and injury-prevention exercises suited to adolescent athletes.
