Anatomy and physiology
- 1The skeletal systemIntro
- Structure of the skeleton — axial and appendicular
- Functions of the skeleton — support, protection and movement
- Types of bone — long, short, flat and irregular
- Types of joint — hinge, ball and socket and pivot
- Ligaments, tendons and injury at joints
- 2The muscular systemIntro
- Types of muscle — voluntary, involuntary and cardiac
- Structure of skeletal muscle — origin and insertion
- Antagonistic muscle pairs and joint movement
- Types of muscular contraction — isotonic and isometric
- Major muscles used in sport and muscle fatigue
- 3The cardiovascular systemIntro
- Structure of the heart — chambers, valves and blood vessels
- Double circulatory system and blood flow through the heart
- Blood vessels — arteries, veins and capillaries
- Composition and functions of blood
- Cardiac output, stroke volume and heart rate
- 4The respiratory systemIntro
- Structure of the respiratory system
- Mechanics of breathing — inspiration and expiration
- Gaseous exchange at the alveoli
- Transport of oxygen and carbon dioxide in the blood
- Tidal volume, vital capacity and minute ventilation
- 5The short-term effects of exerciseIntro
- Increased heart rate, stroke volume and cardiac output
- Increased breathing rate and depth
- Redistribution of blood to working muscles
- Role of adrenaline and glycogen use
- Oxygen debt, lactic acid and muscle fatigue
- 6The long-term effects of exerciseIntro
- Cardiac hypertrophy and resting heart rate
- Increased lung capacity and VO₂ max
- Hypertrophy, capillarisation and increased strength
- Increased bone density and joint stability
- Improved flexibility and reduced injury risk
