VO2max is the maximum rate of oxygen consumption as measured during incremental exercise. Maximal oxygen consumption reflects the aerobic physical fitness of the individual, and is an important determinant of their endurance capacity during prolonged, sub-maximal exercise. The name is derived from V – volume, O2 – oxygen, max – maximum.

Higher VO2 max means your muscle cells consume higher amount of oxygen and you are therefore fitter.

Accurately measuring VO2 max involves a physical effort sufficient in duration and intensity to fully tax the aerobic energy system. In general clinical and athletic testing, this usually involves a graded exercise test (either on a treadmill or on a cycle ergometer) in which exercise intensity is progressively increased while measuring:

•ventilation and

•oxygen and carbon dioxide concentration of the inhaled and exhaled air.

VO2 max is reached when oxygen consumption remains at a steady state despite an increase in workload.

VO2max can be estimated by performing the Cooper’s Test. This test was designed by Kenneth H Cooper for the US military. And interestingly our NS 2.4km run is based on this test. In Cooper’s test a runner has to run/walk for 12 full minutes. The distance covered (D12) in 12 minutes is then used to calculate the runner’s VO2max.

Researchers at the Norwegian University of Science and Technology has developed a fitness age calculator.

Taking information on your physical measurements and workout regime, the program calculates your VO2 Max.

VO2 Max is influenced by your age and gender but is determined by your workouts.
