In other words, he consumed about 42.12 milliliters of oxygen for every kilogram that he weighed during each minute of his 1.5-mile run. Using Table 1, his oxygen consumption for this particular running time is 42.12 ml/kg/min, or simply 42.12. Let’s suppose that a 35-year-old man ran 1.5 miles in 12 minutes 30 seconds. Table 2 shows norms for oxygen consumption in absolute terms based on age and gender.2,6 Oxygen consumption: Absolute These values are an absolute measure of how much oxygen is consumed in milliliters per kilogram of bodyweight per minute (or ml/kg/min). Various running times are given in five-second intervals between eight minutes and 15 minutes 55 seconds. Table 1 lists predicted values of oxygen consumption based on the time it takes to run 1.5 miles. While the results of the 1.5-mile running test are an excellent predictor of oxygen consumption,3 it’s important to realize that this test favors runners. Running on an indoor or outdoor track is preferred. For this field test to be as accurate as possible, distance must be precise and running must take place on a level surface. (A 1-mile running test is more suitable for adolescents and the elderly.) The primary objective of this test is to run 1.5 miles in the least amount of time. One of the most popular field tests used to determine oxygen consumption is the 1.5-mile running test. Certain field tests have a high correlation to laboratory test results. A much more practical way to assess oxygen consumption without the drawbacks of laboratory testing is field testing performed outside the laboratory. For the average person, however, such tests can be expensive, time-consuming and impractical. Laboratory testing is an excellent means of providing accurate and valid data. This allows for measurement of various physiological responses, including the amount of expired air, heart rate, blood pressure and body temperature - all of which can help determine the amount of oxygen being consumed. Each of these methods makes it possible to exercise at different levels of intensity while maintaining a relatively stable position.

Other methods are stepping up and down on a bench of standard height at a fixed rate, or pedaling a bicycle ergometer (a device that measures work) in an upright or a recumbent position using the legs and/or arms. The most widely used method is the motor-driven treadmill. There are a number of ways to accurately measure oxygen consumption in a laboratory. Oxygen consumption is also affected by age, gender and body size. Like virtually all of a person’s other physiological characteristics, potential for aerobic fitness is greatly influenced by genetics. Oxygen consumption is considered the best indicator of a person’s level of aerobic fitness. Reference: A Practical Approach to Strength Training, 3rd edition.
