Across
  1. 1. the total volume of air breathed in and out of the lungs in one breath(L/breath)
  2. 5. the force of your blood on your artery walls during heart contraction
  3. 6. the movement of gases (including oxygen and carbon dioxide) between the alveoli (lungs) and the capillaries (blood)
  4. 8. exercise intensity that can be maintained up to but not exceeding 85 percent of your maximum heart rate
  5. 9. the maximum amount of oxygen able to be taken up by, transported to and used by the body for energy production. This value is commonly used to determine an athlete’s capacity to perform in aerobic (endurance) activities
  6. 11. Tiny air sacs at the end of the bronchioles(tiny branches of air tubes in the lungs)where the lungs and the blood exchange oxygen and carbon dioxide
  7. 12. where more blood flow is redirected to the working muscles and less of it goes to other body organs such as the digestive system
  8. 15. body system made up of the muscles and muscle fibres and includes motor units recruitment, muscle temperature, energy substrates, enzyme activity and metabolic by-products
  9. 18. the narrowing of blood vessels supplying the other organs resulting in reduced blood flow where oxygen demand is lower
  10. 20. the total volume of air breathed in and out of the lungs in one minute (L/min)
  11. 25. the widening of blood vessels supplying the other organs resulting in increased blood flow where oxygen demand is higher
  12. 26. Increased blood flow to the muscles, coupled with the heat generated as a by-product of the increased production of ATP during exercise, results in an increase in...
  13. 28. the maximum number of beats your heart can make per minute normally achieved during incremental exercise such as a VO2Max test
  14. 29. the volume of blood ejected from the left ventricle each beat measured in ml/beat
  15. 30. the total volume of oxygen that the body is using for aerobic ATP (energy) production
  16. 31. the body system made up of the airways, lungs and alveoli and includes acute responses of increased tidal volume, respiratory rate ventilation and pulmonary diffusion. Primary function is to take oxygen into the blood
Down
  1. 2. the force of your blood on your artery walls in between beats, during heart relaxation
  2. 3. the number of time the heart contracts in one minute measured in bpm
  3. 4. the volume of blood ejected from the left ventricle per minute measured in L/min
  4. 7. term used to describe a straight-line relationship between two variables such as heart rate and exercise intensity
  5. 10. These are involved in all of the chemical processes that produce energy via the three energy pathways. There activity increases in the muscle in response to exercise
  6. 13. the amount of oxygen consumed during the recovery period after the cessation of an exercise bout that is over and above the amount usually required during rest
  7. 14. the maximum volume of oxygen that the body is using for aerobic ATP (energy) production achieved during incremental exercise to exhaustion
  8. 16. the state in which there is a discrepancy (shortfall) between oxygen supply and demand and the oxygen needed to meet the energy requirements of the activity. Under these conditions the anaerobic pathways must supplement the energy demands of the activity.
  9. 17. the difference in oxygen content between the arteries and veins
  10. 19. the body system made up of the heart, blood and blood vessels with the primary function of transporting oxygen and nutrients
  11. 21. the total number of breaths taken in one minute (breaths/min)
  12. 22. the state in which oxygen supply equals oxygen demand so that virtually all of the required ATP to maintain the current exercise intensity is being supplied aerobically.
  13. 23. the body's immediate, short term changes that occur in response to exercise. usually to increase oxygen uptake
  14. 24. the amount of oxygen transported to, taken up by and used by the body for aerobic energy production
  15. 27. o reach a state or level of little or no increase or decrease; to remain at a stable level or to level off
