  1. Textbook Questions

  2. Define a-vO2 difference The difference between the amount of O2 In the artery and in the vein

  3. Define Asthma and give one symptom of this disease. Asthma is a disease characterized by spam of the smooth muscle that line the respiratory system Dyspnea: shortness of breath

  4. Define COPD and give one symptom of the disease. Chronic obstructive pulmonary disease This disease leads to a dramatic reduction in airflow through the respiratory system.

  5. What is VO2 Max? The maximum volume of Oxygen that the human body can use in one minute. Fick Equation: VO2 Max= Q X a-vO2 difference Cardiac Output X the difference in O2 between the arteries and the veins.

  6. What is VO2 Max? VO2 maxis the maximum capacity of an individual's body to transport and use oxygen during intense exercise which reflects physical fitness. http://www.youtube.com/watch?v=4l8M5P__Qd8

  7. Is it true that an individual with a high VO2 Max is a better athlete than those with a lower VO2 Max? No, there are many factors to consider in competition. http://www.youtube.com/watch?v=3r-ganOuV78

  8. Name 3 athletes that have a high VO2 Max. Lance Armstrong, Bjorn Daehlie, Frank Shorter, Grete Waitz, Miguel Indurain.

  9. Describe how each of the following systems can potentially limit VO2 Max. Respiratory System: In adequate ventilation and oxygen diffusion Cardiovascular: in adequate blood flow or inadequate oxygen-carrying capacity. Working Muscle: lack of mitochondria and metabolic systems.

  10. Describe what is meant by ventilator threshold A point in exercise where ventilation Increases much more rapidly than work-load.

  11. Describe how ventilatory threshold and lactic acid are related It is said that the VT begins once an increase in lactic acid occurs and oxygen is needed to remove it.
