  1. What is Energy?
    Is essentially the capacity to do work.
  2. What is Bioenergetics?
    The study of energy in the human body.
  3. Bioenergetics, looks at how ______________________________
    chemical energy (food) is converted into mechanical energy (work).
  4. During this conversion process, _________________________ are broken and this ________________________________ that is utilized to produce ________________
    • chemical bonds
    • releases energy
    • work (muscle contractions)
  5. At the cellular level, food (carbohydrates, fats, protein) are converted into ________________
    adenosine triphosphate (ATP)
  6. What is ATP?
    Is the body's energy source ( a high-energy molecule) used for bodily functions and physical activity.
  7. There are _________ main bioenergetic pathways that produce ATP.
  8. Which bioenergetic pathways are categorized as anaerobic (without oxygen (O2))?
    • ATP-CP
    • Glycolysis (lactate acid) pathways
  9. Which bioenergetic pathway is classified as aerobic (with oxygen (O2))?
    Oxidative pathway
  10. Collectively, the three main bioenergetic pathways are known as _______________________________________.
    the bioenergetic continuum.
  11. Energy:
    The capacity to do work.
  12. Bioenergetics:
    The study of energy in the human body.
  13. Adenosine triphosphate:
    Energy storage and transfer unit within the cells of the body.
  14. ATP-CP system, aerobic or anaerobic?
  15. ATP-CP use?
    High-intensity, short-duration activity such as heavy weight training.
  16. ATP-CP time?
    Up to approximately 10 sec. of activity.
  17. Glycolysis system, aerobic or anaerobic?
  18. Glycolysis use?
    Moderate to high-intensity, moderate duration activities such as a typical set of 8-12 repetitions.
  19. Glycolysis time?
    30-50 sec. of activity.
  20. Oxidative system, aerobic or anaerobic?
  21. Oxidative use?
    Lower-intensity, longer-duration activities such as walking on the treadmill for 20-30 min.
  22. Oxidative time?
    Activities greater than 2 min.
  23. What are ATP and creatine phosphate (CP) called?
  24. The ATP-CP system is sometimes referred to as the __________________________________.
    phosphagen system.
  25. The ATP-CP system provides energy for _______________________________________
    primarily high-intensity, short-duration bouts of exercise or activity.
  26. ATP-CP characteristics:
    • Used in power and strength forms of training, where heavy loads are used with only a few repetitions or during short sprinting events.
    • Activated at the onset of any activity, regardless of intensity.
    • Ability to produce energy very rapidly in comparison to the other pathways.
  27. Anaerobic:
    • Without oxygen.
    • Activities that do no require oxygen (O2).
