Exercise Capacitance Testing

At Elevation Physicians, your exercise capacity (or 5th Vital Sign) is tested on at least an annual basis.

Science Behind Exercise Capacitance Testing

  • VO2max (Maximum Oxygen Uptake) 
    An active test that measures how your body uses oxygen during exercise. It is a measure of aerobic endurance and is generally considered the best indicator of an individual or athletes cardiovascular fitness. (See VO2max Normative Data Chart)
  • Cardiac Stress
    Measures how well your heart responds to exercise stress and also tests for signs and markers of heart disease. (Only when indicated)
  • Respiratory Exchange Ratio (RER)
    This measurement is useful in deriving which fuel source your body is using (Fats, Proteins, or Carbohydrates)
  • Lactate Threshold
    Point where the lactic acid builds in the muscles due to the body's inability to process it.
  • Resting Metabolic Rate
    Calculates how many calories your body uses in a resting state, allowing for precise measurements of calorie intake vs. calorie output for your individual weight loss and exercise goals.
  • Body Mass Index
    Measures your body fat percentage in order to set healthy weight loss and exercise goals. (See Body Fat % Chart)
  • Pulmonary Function Tests
    Measures the function of the lungs, revealing problems in the way a patient breathes. The tests can determine the cause of shortness of breath and may help confirm lung diseases.
  • Ventilator Threshold
    Point during exercise training at which pulmonary ventilation becomes disproportionately high with respect to oxygen consumption; believed to reflect onset of anaerobic metabolism and lactate accumulation.
