Fitness can be measured by the volume of oxygen you can consume while exercising at your maximum capacity. VO2max is the maximum amount of oxygen in millilitres, one can use in one minute per kilogram of body weight.
Numerous studies show that you can increase your VO2max by working out at an intensity that raises your heart rate to between 65 and 85% of its maximum for at least 20 minutes three to five times a week.
Aerobic fitness is primary for most sports. It is important to think carefully about the fitness level of the individual and choose the test that is most appropriate for their sport or activity.
The objective of these tests is to measure and monitor the development of a individual’s general endurance (VO2max).
