IB Sports Science: A Complete Guide for Parents and Students

Continuing our A-Level and IB Subject Guide Series, this week we take an in-depth look at IB Sports, Exercise and Health Science – an exciting and applied science subject that combines elements of biology, chemistry, physics, and psychology to understand how the human body functions during exercise, training, and sport.

Whether you’re an aspiring athlete, a future physiotherapist, or simply passionate about health and performance, this course provides both the scientific foundation and practical application to explore sport from a professional perspective.

Available at both Standard Level (SL) and Higher Level (HL), Sports Science is a fantastic choice for students who want to connect classroom science directly to the real world.

What is IB Sports, Exercise and Health Science?

IB Sports Science focuses on the scientific principles behind sport and exercise performance. You’ll learn how muscles work, how the body responds to training, the physics of movement, and the psychology of performance.

The course has a strong practical element — students conduct experiments, collect and analyse performance data, and apply scientific concepts to real-life sporting scenarios.

Core Topics (SL & HL)

✅ Anatomy – Structure and function of the musculoskeletal system.
✅ Exercise Physiology – How the body’s systems respond to exercise and training.
✅ Energy Systems – How the body produces and uses energy during activity.
✅ Movement Analysis – Biomechanics, forces, and motion in sport.
✅ Skill in Sport – Motor skills, learning, and performance psychology.
✅ Measurement and Evaluation of Performance – Testing and data analysis in sport science.

HL students study additional topics in greater depth, including nutrition, training programme design, and advanced biomechanics.

How is IB Sports Science Assessed?

Assessment is split between external exams and an Internal Assessment (practical investigation).

External Assessment – 76% of Final Grade (SL) / 80% of Final Grade (HL)

📌 Paper 1 – Multiple-choice questions on core content.
📌 Paper 2 – Data-based questions, short-answer, and extended-response questions.
📌 Paper 3 (HL only) – Questions on additional HL topics and option material.

Internal Assessment (IA) – 24% of Final Grade (SL) / 20% of Final Grade (HL)

The IA is a scientific investigation where students design and carry out an experiment related to sports, exercise, or health. Examples include:

• Measuring the effect of warm-up duration on sprint performance.
• Comparing recovery rates between trained and untrained individuals.
• Investigating the relationship between hydration and endurance.

Who is IB Sports Science Helpful For?

This subject is particularly suited to:

• Student athletes who want to understand the science behind performance.
• Those aiming for sports-related university degrees (Sports Science, Physiotherapy, Coaching, Kinesiology, Exercise Physiology).
• Future health and medical professionals with an interest in human biology and movement.
• Students passionate about fitness, coaching, or rehabilitation careers.

Subjects IB Sports Science Combines Well With

Because the course draws on multiple scientific disciplines, it pairs particularly well with:

• Biology – Strong crossover in anatomy, physiology, and cell biology.
• Chemistry – Useful for understanding metabolism, energy production, and nutrition.
• Psychology – Links to motivation, performance anxiety, and skill acquisition.
• Mathematics – Helpful for data analysis and statistical evaluation in the IA.

Why Sports Science is a Great Choice

• Applies Science to the Real World – You see immediate relevance in sport, health, and fitness.
• Hands-On Learning – Lab work and field tests develop practical skills alongside theory.
• Interdisciplinary Approach – Integrates biology, physics, and psychology into one subject.
• Career Versatility – Opens pathways into sport, health, science, and education sectors.
• Builds Transferable Skills – Data handling, experiment design, teamwork, and critical thinking.

The Hardest Parts of IB Sports Science

❌ Memorising Anatomy & Physiology – Learning muscles, bones, and energy systems can be content-heavy.
❌ Biomechanics – Applying physics concepts to human movement can be challenging.
❌ Data Analysis – Interpreting results and linking them to theory is essential for the IA.
❌ Balancing Theory and Practice – Success requires excelling in both the written exams and practical investigation.
