Assess students' ability to design and justify a developmentally appropriate, evidence-based 6-week training and nutrition plan for a middle school (grades 6–8) student to safely improve cardiovascular endurance and muscular strength while preventing injury and supporting healthy growth. Tasks should include: setting measurable goals; selecting age-appropriate aerobic and strength activities with progressive overload and recovery strategies; incorporating warm-ups, cool-downs, cross-training, rest/sleep and injury-prevention measures; outlining balanced nutrition priorities (energy needs, macronutrient balance, hydration, timing) and when to seek parental/medical clearance; and explaining monitoring, modification, and safety checks. Responses must explain the developmental rationale and adaptations for individual differences.
