Topic Synopsis
Applied anatomy and physiology covers the structure and function of the musculoskeletal and cardio-respiratory systems, the mechanics of breathing, aerobic and anaerobic exercise, and the short and long-term effects of exercise on the body.
Key Concepts & Core Principles
- Health is a state of complete physical, mental and social wellbeing, not merely the absence of disease or infirmity (WHO definition).
- Fitness is the ability to meet the demands of the environment; it is specific to the activity and can be improved through training.
- The 11 components of fitness: cardiovascular endurance, muscular endurance, muscular strength, flexibility, body composition, speed, power, agility, coordination, balance, and reaction time.
- The three types of wellbeing: physical (e.g., reduced risk of disease), mental (e.g., stress relief, improved self-esteem), and social (e.g., teamwork, friendships).
- Sedentary lifestyle is a major risk factor for obesity, type 2 diabetes, cardiovascular disease, and poor mental health.
Exam Tips & Revision Strategies
- Use specific sporting examples to illustrate physiological concepts
- Ensure you can label diagrams of the heart and skeleton accurately
- Practice calculating cardiac output and interpreting data from graphs
- Be precise with terminology (e.g., distinguishing between concentric and eccentric contractions)
- Link physiological changes to the intensity and duration of exercise
Common Misconceptions & Mistakes to Avoid
- Confusing agonist and antagonist roles
- Incorrectly identifying joint types
- Failing to link muscle contractions (isometric/isotonic) to specific sporting actions
- Misinterpreting heart rate graphs or spirometer traces
- Confusing the definitions of aerobic and anaerobic exercise
- Inaccurate identification of blood vessel structures and functions
Examiner Marking Points
- Identification of specific bones and muscles
- Understanding the role of synovial joint structures in preventing injury
- Explaining the antagonistic muscle action at major joints
- Describing the pathway of air and blood through the body
- Explaining gaseous exchange at the alveoli
- Calculating cardiac output (Q = stroke volume x heart rate)
- Interpreting spirometer traces
- Distinguishing between aerobic and anaerobic exercise
