Nutrition, Hydration and Ergogenic Support
Explain how energy intake, nutrients, hydration and permitted ergogenic strategies affect preparation, performance and recovery.
How to study A-level Physical Education theory
Learn the mechanism, apply it to a precise sporting context, use quantitative or source evidence where relevant and reach a supported judgement.
Core concepts
Concept 1
Carbohydrate, fat and protein have distinct roles in energy supply, tissue repair and adaptation, while micronutrients support normal function.
Exam cue: Match the nutritional strategy to task duration, intensity, environment and recovery window.
Concept 2
Hydration status and thermoregulation affect cardiovascular strain, performance and recovery.
Exam cue: Distinguish energy balance from the proportions and timing of nutrients.
Concept 3
Dietary and ergogenic strategies must be evaluated for evidence, timing, dose, legality, ethics and individual risk.
Exam cue: Evaluate a supplement claim using evidence and risk rather than popularity.
Targeted study blocks
Knowledge for written assessment
Secure the shared theoretical core
Learn shared nutrient functions, energy balance, hydration, pre/during/post-exercise strategies and the principles for evaluating ergogenic aids.
Apply and evaluate
Turn knowledge into a supported sporting judgement
Use the activity demand and individual context to justify a nutrition or hydration strategy and acknowledge evidence and safety limitations.
Risk pitfalls and guardrails
Saying protein is the main fuel for high-intensity work.
Guardrail: Do not replace theoretical explanation with an activity-specific technique description or practical-performance instruction.
Assuming every athlete needs the same diet or fluid volume.
Guardrail: Do not replace theoretical explanation with an activity-specific technique description or practical-performance instruction.
Treating legal, effective and safe as the same judgement.
Guardrail: Do not replace theoretical explanation with an activity-specific technique description or practical-performance instruction.
Memory anchors
Carbohydrate
Carbohydrate supplies glucose and glycogen for exercise, especially as intensity rises.
Protein
Protein supports tissue repair, adaptation and other body functions rather than serving as the usual primary fuel.
Hydration
Hydration supports blood volume, thermoregulation and physiological function.
Energy balance
Energy balance compares energy intake with total energy expenditure.
Ergogenic aid
An ergogenic aid is a strategy or substance intended to enhance performance or recovery.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
