  1. Acute Mountain Sickness
    A common ailment upon first arriving at high altitude characterized by headache, dizziness, lightheadedness, and nausea due to lowered oxygen intake or respiratory alkalosis.
  2. Aerobi
    The production of energy by metabolism in the presence of oxygen
  3. Aerobic Capacity
    The highest rate at which oxygen can be consumed in metabolism
  4. Aerobic Power
    The aerobic capacity per body weight
  5. Alveoli
    The tiny air sacs in the lungs across the surface of which the oxygen and carbon dioxide are exchanged with blood
  6. Barometric Pressure
    The pressure of the atmosphere as measured by a barometer
  7. Cerebral Edema
    The accumulation of fluid in brain tissue
  8. Cerebral Edema
    The accumulation of fluid in brain tissues
  9. Chronic Mountain Sickness
    A condition of natives or long-term residents of high altitude characterized by a loss of acclimatization, lowered ventilation rate, and a great increase in polycythemia.
  10. Edema
    An abnormal accumulation of fluid resulting in swelling
  11. Hemoglobin
    The protein that gives redblodded cells their color and their capacity to transport oxygen and carbon dioxide
  12. Hypoxia
    Low oxygen levels
  13. Muscle Strength
    The amount of force a muscle can provide based ont he cross sectional area of muscle
  14. Natural Hazards
    Naturally occurring perils such as storms, earthquakes, tsunamis, and volcanic eruptions
  15. Optimal foraging Strategies
    Foraging techniques that are most effective or efficient
  16. Phsycial Fitness
    The ability to maintain homeostatic conditions during strenuous activity or to rapidly restore those conditions after exercise
  17. Plycythemia
    A condition in which the percent of blood occupied by red blood cells increase from the 43-37 percent to well over 50 percent on the average.
  18. Pulmonary Edema
    The accumulation of fluid in the lungs, blocking oxygen transport
  19. Sub acute infantile mountain sickness
    A condition found in some infants born or brought to high altitude, characterized by low oxygen levels in blood, elevated levels of polycythemia, and a high risk of mortality
  20. Tsunamis
    A seismic sea wave
  21. Ventilation Rate
    The expansion of superficial blood vessels, which increase the rate of heat loss from the body to the air.
  22. Ventilary Drive
    The sensitivity of ventilation rate to hypoxic exposure
  23. Work Capacity
    The ability to use oxygen at a fast rate
