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
- Components of fitness: Health-related (cardiovascular endurance, muscular strength, muscular endurance, flexibility, body composition) and skill-related (agility, balance, coordination, power, reaction time, speed).
- Principles of training: SPORT (Specificity, Progression, Overload, Reversibility, Tedium) and FITT (Frequency, Intensity, Time, Type) to optimise training adaptations.
- Methods of training: Continuous, fartlek, interval, circuit, weight, plyometric, and flexibility training, each with specific benefits and applications.
- Training zones: Calculating and using target heart rate zones (e.g., 60-80% of maximum heart rate) for aerobic and anaerobic training.
- Injury prevention: Importance of warm-up (pulse raiser, stretching, skill practice) and cool-down (light activity, stretching) to reduce injury risk and aid recovery.
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
