How to Revise Communication Topics for IB SEHS
Communication is one of the first topics students encounter in IB Sports, Exercise and Health Science (SEHS), and it forms the foundation for many later concepts. Effective revision of communication topics is essential because they appear frequently in short-answer, data-based, and extended-response questions.
Strong revision is not about memorising definitions. Instead, it focuses on understanding processes, using correct terminology, and applying ideas to exercise and performance.
Know the Core Systems First
Effective revision starts with a clear understanding of the two main communication systems:
- The nervous system
- The endocrine (hormonal) system
Students should be able to clearly explain how these systems differ in speed, duration, and method of transmission. Mixing these systems is one of the most common reasons marks are lost in exams.
When revising, always practise explaining how each system contributes to movement and exercise regulation rather than learning them in isolation.
Focus on Processes, Not Just Definitions
Communication topics are process-based. This means examiners expect students to describe sequences clearly and in the correct order.
Key processes to practise include:
- Action potential transmission
- Communication at the neuromuscular junction
- Feedback mechanisms during exercise
When revising, write step-by-step explanations using correct IB terminology. This helps ensure clarity and prevents skipping important stages in exam answers.
Use Exercise Context in Every Answer
Another common revision mistake is separating theory from application. In IB SEHS, communication must always be linked to exercise or performance.
Good revision strategies include:
- Explaining how communication changes with exercise intensity
- Linking fatigue to reduced communication efficiency
- Applying nervous system control to specific movements
Practising applied explanations improves both understanding and exam performance.
Practise Exam-Style Questions Regularly
Regular exam practice is essential for mastering communication topics. This allows students to refine structure, timing, and terminology.
When reviewing answers:
- Check for clear sequencing
- Ensure correct terminology is used
- Confirm links to exercise are included
Self-marking using markscheme language can significantly improve response quality.
Build Confidence Through Consistency
Revising communication little and often is more effective than last-minute cramming. Revisiting core concepts regularly helps reinforce understanding and improves recall under exam pressure.
Strong communication knowledge also supports later topics such as biomechanics, motor learning, and injury prevention.

Frequently Asked Questions (FAQs)
What should I focus on most when revising communication?
Focus on understanding processes such as action potentials, neuromuscular junctions, and feedback mechanisms rather than memorising definitions alone.
How much detail do IB exam answers need?
Answers should be clear, structured, and use correct IB terminology. Including step-by-step explanations linked to exercise is key.
How often should I revise communication topics?
Regular revision throughout the course is best. Revisiting core ideas weekly helps maintain understanding and reduces exam stress.
