The flashcards below were created by user jpowell22 on FreezingBlue Flashcards. What would you like to do?


  1. What is the bodys maximal oxygen consumption?
    VO2max
  2. What is oxygen consumption influenced by?
    • age
    • gender
    • heredity
    • inactivity
    • disease
  3. What is the ability to work for prolonged periods of time and ability to resist fatigue?
    endurance
  4. What is the ability to perform repeated contractions of a specific m. group over a period of time?
    muscular endurance
  5. What is the ability to perform large muscle exercise for long periods of time?
    cardiovascular endurance
  6. What is aerobic exercise training?
    • exers program to improve the energy capacity of a m.
    • exers must be sufficient intensity, duration, and frequency
  7. How long does it take to see significant changes in aerobic programs?
    10-12 weeks
  8. What is adaptation of aerobic exers dependant on?
    • ability of organism to change
    • training stimulus threshold
  9. What occurs with prolonged bed rest or extended illness?
    deconditioning
  10. Why does the body adjust circulation during exers?
    • increase O2 and nutrients
    • remove carbon dioxide and lactic acid
    • dissipate excessive heat
  11. What is the rate a conditioning response occurs at? (HR)
    70-85% of max HR
  12. How do you determine ones HR using the Karnovens formula?
    • young n healthy= 220-age
    • exercise HR= HR(at rest) + 60-70%(max HR- rest HR)

    older at risk or with coronary artery disease may be as low as 40-60% of their max HR
  13. Who developed the rate of perceived exertion (RPE) scale?
    Borg
  14. Using the RPE scale, what is considered very, very light exers?
    6-8
  15. Using the RPE scale what is considered very light?
    9-10
  16. Using the RPE scale, what is considered fairly light exers?
    11-12
  17. Using the RPE scale, what is considered somewhat hard exers?
    13-14
  18. Using the RPE scale, what is considered hard?
    15-16
  19. Using the RPE scale, what is considered very hard?
    17-18
  20. Using the RPE scale, what is considered very very hard?
    19-20
  21. What artery is ant. to the SCM?
    carotid pulse
  22. What artery is midwat between the elbow and shoulder on the medial arm?
    brachial pulse
  23. Where is the radial pulse?
    wrist, lateral to the carpi radialis tendon
  24. Where is the ulnar pulse?
    between flexor digitorum superficialis and flexor carpi ulnaris
  25. What is the amt of blood pumped out of the heart per minute?
    cardiac output
  26. What is stroke volume?
    amt of blood ejected by the ventricle during contraction
  27. What is the blood volume of adults?
    7-8% of bodyweight
  28. What is the MET (metabolic equivalents)?
    amt of oxygen consumed per kilogram of bodyweight per minute to perform a given activity

    normal at rest= 3.5ml/kg/minute
