ACE literature states that you probably won’t ever use the formula in real life and you won’t be tested on it, so why do you need to understand the Fick Equation? Because the Fick Equation measures:
  1. The rate at which the body uses oxygen during physical activity
  2. The rate at which the body burns calories during physical activity
  3. The relationship between respiratory rate and heart rate during physical activity
  4. The rate at which the muscles use glycogen during physical activity
Explanation
Answer: A - The Fick Equation, expressed as the volume of oxygen (VO2) equaling (stroke volume x heart rate) x oxygen extraction, determines the rate at which the body uses oxygen during physical activity. Your maximum VO2 is the largest amount of oxygen you can take in and use. The concept of “Max VO2” is typically used to measure how aerobically fit an individual is. Although genetics plays a huge role in an individual’s VO2 max, properly designed training can certainly play a part as well.
