Core Topics and Curriculum Structure
The Sports Exercise and Health Science IB course covers six main topic areas, each exploring different aspects of exercise science and health. Students study these topics at either the Standard Level (SL) or Higher Level (HL), with HL students covering additional sub-topics and engaging in more extensive practical investigations.
Anatomy and Physiology
This foundational topic examines the structure and function of the human body systems relevant to exercise and health. Students learn about the skeletal system, muscular system, cardiovascular system, and respiratory system, understanding how these systems work together to enable physical activity and maintain homeostasis during exercise.
Key areas of study include:
- Muscle structure and contraction – understanding how skeletal muscles generate force and movement
- Energy systems – exploring the ATP-PC, glycolytic, and oxidative systems that provide energy for different activities
- Cardiorespiratory adaptations – learning how the heart and lungs respond to training stimuli
- Homeostasis – understanding how the body maintains internal balance during physical stress
Biomechanics
Biomechanics applies principles of physics to human movement, analyzing the forces that act on and within the body during physical activity. Students learn to describe and explain movement using scientific terminology and mathematical relationships The details matter here..
This topic covers:
- Linear and angular kinematics – describing motion in terms of displacement, velocity, and acceleration
- Kinetics – understanding the forces that cause or control movement
- Projectile motion – analyzing the factors affecting the trajectory of objects in sport
- Lever systems – examining how the body uses mechanical advantage to produce movement
Exercise Physiology
Exercise physiology focuses on how the body adapts to training and how these adaptations improve performance and health. Students explore the principles of training, the physiological responses to exercise, and the long-term adaptations that occur with consistent physical activity.
Students examine:
- Principles of training – including specificity, overload, reversibility, and individual differences
- Aerobic and anaerobic training – understanding different training methods and their physiological effects
- Detraining and detraining effects – exploring what happens when training stops
- Environmental factors – how heat, cold, altitude, and other conditions affect exercise performance
Nutrition and Energy Systems
Proper nutrition is fundamental to both health and athletic performance. This topic examines the role of macronutrients, micronutrients, and hydration in supporting physical activity and recovery.
Students learn about:
- Macronutrients – carbohydrates, proteins, and their roles in energy production and tissue repair
- Micronutrients – vitamins and minerals essential for metabolic processes
- Hydration – understanding fluid balance and the effects of dehydration
- Ergogenic aids – examining nutritional and pharmacological substances that may enhance performance
- Dietary planning – applying nutritional principles to different sporting contexts
Sports Psychology
The mental aspect of sport and exercise is just as important as the physical. Sports psychology explores how psychological factors influence performance, participation, and wellbeing in physical activity Small thing, real impact..
This topic includes:
- Motivation – understanding why people engage in and persist with exercise
- Arousal and anxiety – examining the relationship between psychological arousal and performance
- Group dynamics – exploring teamwork, leadership, and cohesion in sport
- Mental training techniques – including visualization, self-talk, and goal setting
- Burnout and overtraining – understanding the psychological consequences of excessive training
Measurement and Assessment
Scientific inquiry requires accurate measurement and assessment. This topic develops students' understanding of research methods, data collection, and analysis in sports science contexts.
Students study:
- Laboratory and field tests – learning various methods for assessing fitness components
- Reliability and validity – understanding what makes a good test
- Data analysis – developing statistical skills to interpret research findings
- Ethical considerations – examining issues of consent, privacy, and safety in research
Assessment Components in Sports Exercise and Health Science IB
The IB assessment model for Sports Exercise and Health Science combines external and internal evaluation to ensure students demonstrate both theoretical understanding and practical skills Small thing, real impact..
External Assessment
The external examination consists of three papers taken at the end of the two-year course:
- Paper 1 – Multiple choice questions testing knowledge and understanding across all topics
- Paper 2 – Short answer and extended response questions requiring application and analysis
- Paper 3 – Data-based questions that assess students' ability to interpret research findings and practical scenarios
Higher Level students answer additional questions that reflect the extended content of the HL course Turns out it matters..
Internal Assessment: The Practical Investigation
The internal assessment component requires students to design and conduct their own scientific investigation related to sports, exercise, or health. This individual investigation allows students to apply the scientific method to a research question of personal interest Easy to understand, harder to ignore..
Students must:
- Formulate a testable research question
- Design a methodology that collects sufficient, relevant data
- Analyze their results using appropriate statistical methods
- Evaluate their investigation, including limitations and improvements
- Communicate their findings in a formal scientific report
This internal assessment component is worth 20% of the final grade and provides valuable experience in scientific research and critical thinking.
