Assess students' ability to analyze how nutrition, hydration, sleep, and training load interact to affect performance, recovery, and injury risk in middle school athletes. Scope includes grade 6–8 appropriate physiological concepts, interpretation of simple case scenarios and basic data (sleep hours, fluid and snack timing, macronutrient balance, practice duration/intensity), identification of risk patterns, and development and justification of practical, evidence-informed adjustments to training, rest, and fueling to optimize outcomes and reduce injury.
