How do I revise E2E stub topic for AQA A-Level?

When answering an essay question, clearly structure your response by identifying the activity's intensity and duration first, then discuss the relevant energy system contributions.

What exam tips are there for E2E stub topic? (2)

Use specific sporting examples and include numerical data (e.g., intensity percentages, time ranges) to support your explanations of the energy continuum.

What mistakes should I avoid in E2E stub topic?

Assuming one energy system works in complete isolation; students often forget that all three systems are active simultaneously, with one predominating.

What are common errors in E2E stub topic exams? (2)

Confusing the terms 'lactic acid' and 'lactate' and failing to distinguish the role of lactate as a fuel rather than purely a fatigue agent.

E2E stub topic

AQA

A-Level

This subtopic examines the body's energy production mechanisms during physical activity, focusing on the adenosine triphosphate (ATP) resynthesis pathways. It explores the characteristics, fuel sources, and limitations of the ATP-PC, glycolytic, and aerobic systems, and how they integrate to meet energy demands. Understanding these systems is crucial for optimising training, performance analysis, and recovery strategies in sport and exercise.

Key skills and knowledge for this topic

Award credit for correctly linking the ATP-PC system to high-intensity, short-duration activities (e.g., 100m sprint, powerlifting) with an understanding of phosphocreatine depletion.
Award credit for identifying that the glycolytic system produces ATP anaerobically with lactic acid as a by-product, and its effectiveness in events lasting 30-90 seconds.
Award credit for demonstrating the ability to calculate/interpret the energy continuum, explaining when each system predominates during a mixed-intensity sport like football.
