Transcript

  • 1. The Components of Fitness
  • 2. PHYSICAL FITNESS • THE ABILITY OF THE BODY TO ADAPT TO THE DEMANDS AND STRESSES OF PHYSICAL EFFORT. • Fitness itself can not be described in a single definition, but must be looked at in its ten separate components.
  • 3. Health Related COMPONENTS OF FITNESS Flexibility Strength Speed Power Aerobic Capacity Muscular Endurance Agility Balance Co-ordination Body Composition (Anaerobic Capacity)
  • 4. Flexibility • Flexibility – the ability of your muscles, ligaments and tendons to stretch so that your joints allow large range movements.
  • 5. Strength • Muscular strength – the force that a muscle or group of muscles can generate against a resistance in a single contraction.
  • 6. Factors Affecting Strength • • • • • • Recruitment of muscle fibres Cross-sectional area of a muscle Prestretch Muscle fibre types Age gender
  • 7. Anaerobic Capacity • Anaerobic Capacity (Speed) - the ability to get your body moving quickly. • Uses anaerobic energy system (I.e. no oxygen but P-Cr and Lactic acid Explosive energy systems). Energy
  • 8. POWER • Power is the functional application of both strength and speed. It is the key component for most athletic performances. • Muscular Power – the ability to use a lot of strength very quickly to produce an explosive effort.
  • 9. Balance • Balance – your ability to maintain the body in equilibrium while you are moving (dynamic) or stationary (stationary).
  • 10. Muscular Endurance • Muscular Endurance – the ability of your muscles to produce small efforts that are repeated over and over again.
  • 11. Aerobic Capacity • The ability to keep producing energy aerobically and using it to perform tasks involving the whole body for extended periods of time • Aerobic capacity depends on the ability of your heart and lungs to deliver oxygen through your blood to your muscles, to produce aerobic energy. • Long duration, low intensity.
  • 12. Agility • Agility – your ability to change direction quickly and precisely and still retain balance. • To be agile , you must be able to accelerate quickly, turn, dodge and weave.
  • 13. Co-ordination • Coordination – the ability to time your movements so that you perform skills smoothly and accurately.
  • 14. Body Composition • Body composition the ratio of the different types of tissue in your body (fat, muscle, bone).
