VO2max is the maximum capacity for oxygen consumption by your body during maximum exertion. This is also known as aerobic power or maximal oxygen intake/consumption. VO2max is a commonly used determinant of aerobic (cardiovascular) fitness. The most accurate way of determining your individual VO2max is to perform a maximal exercise stress test in a laboratory. Aerobic fitness relates to how well your cardiovascular system works to transport and utilize oxygen in your body. VO2max is used in the estimation of energy expenditure.
Note:
•VO2max is used in Program creation. If you do not know this value, you can determine a comparable value, your OwnIndex, by performing the Polar Fitness Test. For further information, see the section Test Your Fitness Level - Get Your OwnIndex.
