    Measuring VO2 max It is important that you understanding what VO2 max. is and what is means to the endurance athlete. As you know, VO2 max. refers to the Maximum Volume of Oxygen that you can use, or the amount of oxygen you use at maximal levels. To determine VO2 max, all one needs to do is measure the amount of oxygen used during a minute of maximal work. You may have seen a picture of a person competing a VO2 max. test on a treadmill. They wear an apparatus with a tube going into their mouth and a peg on their nose. All breathing is done through the mouth, and a machine measures the amount of oxygen going into the mouth and the amount of oxygen coming out. The difference between the two is the oxygen used by the body. They measure it over a minute (or 30 seconds multiplied by 2) to get a figure in litres per minute (l/min). View the video showing one method of measuring VO2 max. While a person is standing on the treadmill before the test begins, we can measure his/her VO2 at rest (usually about 0.5 litre/minute). This is the amount of oxygen required to keep the body going at rest (that is; heart beating, lungs breathing, brain working, etc.) As they begin exercising, the subject's VO2 increases as the intensity of exercise increases. This increase is usually done gradually over a period of 15-20 minutes. If the intensity is increased too rapidly, the amount of lactate produced is likely to fatigue the muscles before the person reaches maximal heart rate. The idea is to get the person working at maximal intensity (max. HR) for 30 seconds or 60 seconds, and measure the amount of oxygen being used by the body. This is the person's VO2 max.
