1.2.4 - A healthy, active lifestyle and your muscular system.
- Effects of exercise.
  - Long term
    - Hypertrophy - increase muscle mass.
    - Improve posture
    - Increase tendon strength
    - Decrease risk of injury
  - Short term
    - Increase demand for oxygen and glucose/glycogen.
    - Increase amount of waste products (CO2).
    - Lactic Acid could be produced if not enough oxygen is delivered.
      - Oxygen Debt - amount of oxygen consumed during recovery above that which would ordinarily have been consumed in the same time at rest.
- Muscles
  - Latissimus Dorsi
  - Deltoid
  - Abdominals
  - Gastrocemius
  - Trapezius
  - Pectorals
  - Gluteals
  - Quadriceps
  - Hamstrings
  - Triceps
    - Antagonistic muscle pairs - create movement when one (prime mover) contract and the other (agonist) relaxes.
      - Deltoid
      - Pectorals
      - Quadriceps
      - Hamstrings
  - Biceps
    - Antagonistic muscle pairs - create movement when one (prime mover) contract and the other (agonist) relaxes.
- Types of Muscle
  - Cardiac - unique to the heart. Never tires.
  - Involuntary - work the internal organs. We do not consciously control these muscles.
  - Voluntary - makes our body move. Attached to the skeleton and can be controlled.
- Muscle fibres
  - Slow Twitch
    - Contract slowly
    - Use oxygen
    - Keep going for long periods of time
    - Endurance athletes - Mo Farah, The Brownlee's.
    - Aerobic activites
  - Fast Twitch
    - Contract quickly
    - Tire quickly
    - Bigger than slow twitch muscles
    - Anaerobic activities
    - Usain Bolt, Greg Rutherford
- Muscle Movements
  - Extension - movement that increase the angle at a joint.
  - Abduction - movement of a limb away from the body.
  - Flexion - movement that decrease the angle at a joint.
  - Adduction - movement of a limb towards the body.
  - Rotation - widest range of movement possible, only produced at ball & socket joints.
- Injury
  - Preventing injury - warm ups and cool downs. Check equipment. Protective clothing/equipment. Using the correct technique.
  - Soft tissue injuries - RICE.
Isotonic
- Eccentric - fibres contract as muscles lengthen.
- Concentric - muscle shortens as fibres contract.
- Muscle contractions
  - Isometric - muscles contract and no movement occurs.
