Another term for aerobic capacity is:
VO₂ max, or maximal oxygen consumption, refers to the maximum amount of oxygen that an individual can use during intense exercise. The greater your VO₂ max, the more oxygen your body can consume, and the more effectively your body can use that oxygen to generate the maximum amount of ATP energy.
A high VO₂ max can be a good predictor of your athletic performance, especially if you’re a runner or a swimmer. While oxygen uptake is more frequently used for athletes, is not just for athletes. It is a way to determine cardiorespiratory fitness in anyone.
Testing should be done under professional supervision as it does require maximal effort and a breathing measurement apparatus. There are also formulas or testers, such as some smartwatches, outside of the clinical setting. Testers can be pricey though.
You can use a 1-mile walk test formula. Is it the same as having your oxygen consumption monitored? Well, not exactly, but it’s good for a starting place. Begin walking as fast as you can without running and use a stopwatch while you walk exactly 1 mile. When you’ve finished walking 1 mile, stop the stopwatch right away and count your pulse for 15 seconds. Then use the formula below.
VO2 max = 132.853 – (0.0769 x your weight in pounds) – (0.3877 x your age) + (6.315 if you are male or 0 if you are female) – (3.2649 x your walking time) – (0.1565 x your heart rate at the end of the test).
Fun, right?

OTHER ANSWERS:
B. Maximum heart rate – Maximum heart rate is the highest number of beats your heart can pump per minute when it’s under stress (physical or otherwise). Your maximum heart rate is about 220 minus your age. It does not get better or worse with fitness. However, it is used to test fitness as the amount of stress increases over time and your heart becomes better adapted to pump oxygenated blood.
C. Cardiorespiratory endurance – Cardiorespiratory endurance is the ability to perform large-muscle, whole-body exercise at moderate to high intensities for extended periods of time.
D. Motor skill ability – Motor skill ability is the ability to manage the process of movement. To execute motor skills, a person’s brain, muscles and nervous system must all work together.
