VO2 max is a measurement of the maximum amounts of oxygen that a person can take into the body, the maximum amount of oxygen that a person can transport through the body, and the maximum amount of oxygen that a person can use to fuel movement. VO2 max represent a physiological limit, and VO2 max serves as a metric for aerobic power. When a person exercises at a high level, a person may reach a physiological ceiling, and this physiological ceiling is the VO2 max.
The VO2 max provides information about cardiovascular efficiency, and the VO2 max shows how well the heart, the lungs, and the blood vessels works together to sustain workloads.
Different sports require different levels of VO2 max, because different sports places different types of demands on the cardiovascular system. For example, cross country skiers often have very high VO2 max levels because cross-country skiing requires a massive full-body effort that utilize a large amount of oxygen. In contrast, a person who plays basketball or tennis may have a lower VO2 max than a marathon runner, but a basketball player or a tennis player require explosive power and quick recovery rather than a steady output.

Therefore, a lower VO2 max does not necessarily mean that a person is less fit, but it does mean that the persons physiological specialty is different than a marathon runner. Age affect the VO2 max of a person, and the VO2 max typically declines as a person gets older. Aerobic capacity naturaly decline over time, so the VO2 max of many people will decrease as the decades pass.
However, staying active can help a person retain a higher VO2 max, and staying active can slow the decline of the VO2 max. A person who leads a sedentary lifestyle will likely have a lower VO2 max than a person who remain active. To increase a VO2 max, a person must introduce variety and intensity into a training routine, because the body becomes efficient at a specific level of exercise and will stop making adaptations if the level of exercise do not change. To improve a VO2 max, a person can use high-intensity interval training to increase the heart rate, and a person can also use long, slow distance training to build the aerobic system.
If a person only performs high-intensity interval training, a person may experience burnout, and if a person only performs long, slow distance training, a person may reach a plateau. Nutrition and recovery is also necessary to improve the VO2 max. A person must consume nutrients that support oxygen transport, and a person must get enough sleep to allow tissues to repair. Improvement in the VO2 max dont happen during the exercise itself, but improvement in the VO2 max happens while a person is resting.
Thus, training is only one part of the process for increasing the VO2 max, and nutrition and recovery are also parts of the process for increasing the VO2 max.
The VO2 max is a tool that a person can use to benchmark progress. The VO2 max tell a person where a person stands in terms of fitness, and the VO2 max helps a person determine which training methods a person should of use to reach a goal. Knowing the VO2 max is a way to understand the limits of the body, and understanding these limits is a step toward increasing the capacity of the body.
