584 Energy Conservation Joint Protection

  1. What are the two major components of Energy Conservation and Joint Protection?
    • 1. Physiological Aspects
    • 2. Biomechanical Aspects
  2. What are the "unseen" considerations?
    • physiological components
    • -muscle fatigue levels
    • -endurance
    • -total body energy expended
  3. The external forces which are applied to
    a particular area. Items which would be included here would be gravity,
    leverage, force required, torque, weight and time.
    Biomechanical components
  4. Biomechanical considerations:
    the pull exerted on all bodies within
    the earth’s sphere
  5. Biomechanical considerations:
    the action or mechanical power of a
    lever. In the case of joint protection, this will refer to the leverage of
    specific limbs and muscles
  6. Biomechanical considerations:
    energy that causes or alters motion
  7. Biomechanical considerations:
    a measure of the tendency of a force to
    cause rotation
  8. Biomechanical considerations:
    heaviness, specific gravity
  9. Biomechanical considerations:
    measure, duration. The period during
    which something exists or happens
  10. the primary indicator of the functional capacity of the circulation to meet the
    demands of physical activity 
    Cardiac Output
  11. Output from the heart as with any pump, is determined by its rate of pumping (_____ ____) and the amount of blood ejected with each stroke (____ _____).
    • heart rate
    • stroke volume
  12. The result of many factors which are related to the specific demands of the
    exercise that ultimately affects either contraction or excitation or both. 
    Muscular Fatigue
  13. A significant reduction in glycogen is related to fatigue during submaximal exercise leading to _______ ______
    nutrient fatigue
  14. In short-term maximal exercise, muscle fatigue is related to oxygen deficiency and increased ____ ______ concentrations
    blood lactate
  15. Staying power -- ability to maintain task
  16. the preservation of physiological reserves
    Energy Conservation
  17. This 5 level classification system is based on the energy required by untrained men
    and women performing different tasks
    The Met
  18. ______ and _______ are 2 very important components in determining the difficulty of particular tasks, from an energy conservation point of view.
    Intensity and duration
  19. the factor distinguishing the manner in
    which a specific work task is completed.
  20. the factor distinguishing the length of
    time it takes to complete the task
  21. True or false?
    How much you weigh will increase the # of mets for the activity
  22. Refers more specifically to the
    biomechanical forces which are involved in the performance of a task or work
    Joint Protection
  23. What are the 5 components to be analysed for joint protection?
    • 1.Joint positioning
    • 2.Static or dynamic actions of muscle
    • groups
    • 3.Force, strength required and strength
    • available
    • 4.Physical properties of the object(s)
    • involved in the task
    • 5.Necessity of the task
  24. Joint protection:
    Avoid positions in the hands which cause ____ ________
    ulnar deviation
  25. Should you employ larger or smaller joints whenever possible?
    Larger joints as they are stronger
  26. Wrist position anything beyond ___ degree is bad
  27. True or false?
    Dynamic is better than static (eg. Lifting a weight not just holding a weight)
  28. How to change the physical properties of the task or object (5)
    • 1. Alter the weight
    • 2. Alter size/grips
    • 3. Alter ego
    • 4. Alter frequency/rate
    • 5. Modify work space
  29. A way of avoiding fatigue by using common
    Energy Conservation
  30. Balance between rest and play.  Not only do you pace the activities but also pace the rate at which you do them
    Activity Pacing
  31. Planning can help you prevent fatigue and overwork. It can also prevent disappointment at not having energy to participate in an activity that is more meaningful to you.
    Planning Activity
  32. 7 Tips for planning activities for energy conservation
    • 1.Allow rest periods throughout the day
    • 2.Be prepared to take a rest at any time, even in the middle of the task.
    • 3. Break up larger tasks into manageable
    • components.
    • 4.Alternate heavy and light jobs.
    • 5.Avoid standing, lifting and holding.
    • 6. Avoid people, situations, and topics of
    • conversation which may upset you, make you tense or angry.
    • 7.Avoid working in very cold or hot temperatures.
