para physiology p1

• What type of exercise does a paramedic do?
• Exercise


  • Energy supply
  • Strength and dexterity with a little endurance
• Topics covered in the lecture

  • A reminder about dexterity
  • The biological basis of strength
  • A little about endurance and biomechanics
• Control of muscle

  Movement
• Strength


  The ability to exert force
• Strength determinants

  Muscle length<|>Muscle contraction speed<|>Muscle fibre type (myosin ATPase isoform)<|>Myofibril number (myofibrillar hypertrophy)<|>Penation<|>Mechanical advantage<|>Leverage<|>Strength Deficit (increased agonist activation)<|>Disinhibition<|>Antagonist inhibition<|>Synchronicity
• Mechanical advantage


  The advantage gained in strength or efficiency in lifting
• Aerobic Exercise


  Exercise that improves the efficiency of the body's cardiovascular system in absorbing and transporting oxygen
• Biomechanics – lifting
