- Sport unit 1B -Muscles
- Cardiac
- Heart
- Does not fatigue
- Has a set rhythm of contraction
- Unconsciously controlled by the nervous system
- Heart
- Smooth
- Stomach
- Unconsciously controlled by the nervous system
- Liver
- Stomach
- Skeletal
- Bicep
- under conscious control
- Fatigues easily
- Critical to sport
- Tricep
- Bicep
- Antagonistic muscle pairs
- One muscle is contracting the other is relaxing
- Synergists
- Assisting the agonist muscle to perform its action
- Neutralising any undesired action at the joint
- Fixators
- Stabilise joint to remove any unwanted movement
- Synergists
- One muscle is contracting the other is relaxing
- Muscle contraction
- Eccentric
- This is where the muscle lengthens
- Concentric
- Contracts and shortens the muscle
- Isometric
- There is little or no muscle contraction
- Eccentric
- Fibre types
- Type 1
- Slow twitch
- Characteristics
- Contract slowly
- Highest resistance to fatigue
- Exert the least amount of force
- utilises the aerobic system

- Playing squash
- Type 1 through endurance training
- Both energy systems
- Aerobic system
- Anaerobic system
- Type 2b
- 110m hurdles
- Characteristics
- Utilise the anaerobic energy system
- Consist of large motor neurones
- Produce a strong force of contraction
- Larger and thicker than other fibre types
- Type 1
- Adaptations
- Hypertrophy
- Increased tendon strength
- Increased energy stores
- Improved use of energy sources
