PAPER 1 - HEALTH AND FITNESS

• What is health? 


  A complete state of positive physical, mental and social well-being not merely the absence of infirmity (by the world health organisation)
• What are the 3 parts of health?

  1. Physical well-being
  2. Mental well-being
  3. Social well-being
• What is fitness?


  The ability to meet the demands of the environment
• What are the health related components of fitness?

  • Flexibility
  • Muscular endurance
  • Cardiovascular endurance
  • Strength
• What are the skill related components of fitness?

  • Coordination
  • Reaction time
  • Agility
  • Balance
  • Speed
  • Power/explosive strength
• What is cardiovascular endurance? 


  The ability of the heart and lungs to supply oxygen to the working muscles
• What is the importance of cardiovascular endurance?

  • Long-duration activity
  • Known as aerobic power due to its demand on the aerobic energy system to supply oxygen needed for muscle contraction
• What is flexibility? 


  The range of movement around a joint
• What is the importance of flexibility?

  • Lowers the risk of injury through overstretching the muscle
  • Improve sporting performance
• What is strength?


  A measure of the force required to overcome a resistance
• What is maximal strength?


  The greatest possible force that a performer is able to exert against a resistance
• What is static strength? 


  The maximum force applied to an immovable object/body
• What is dynamic strength? 


  The force applied by a performer while moving
• What is explosive strength? 


  The ability to apply a large force as quickly as possible
• What is muscular endurance? 


  The ability of the muscles to repeatedly contract for an extended period of time without fatigue
• What is the importance of muscular endurance?

  • For extended duration activities when the muscles must sustain repeated contraction for an extended period time
  • For both long duration, high intensity exercise
  • Important when the same muscle group is used over and over
• What is agility? 


  The ability to change the body's direction quickly and under control
• What is balance? 


  The ability to maintain the centre of gravity over the base of support when still (static) or moving (dynamic)
• What is coordination? 


  The ability to move 2 or more parts of the body at the same time efficiently and accurately
• What is power/explosive strength? 


  The ability to apply a large force as quickly as possible. The product of strength and speed. Short duration and high intensity.
• What is the equation for power?


  Power = strength x speed
• What is speed? 


  The rate at which the body/parts are moved from once place to another. The maximal rate an individual is able to cover a set distance in a period of time.
• What is the equation for speed?

  Speed = distance / time
• What is reaction time? 


  The time taken to respond to a stimulus
