The maximum oxygen intake level can only be measured using the multistage fitness test.

The maximum oxygen intake level (VO2max) is is the maximal rate at which oxygen can be used by the body during exhaustive or maximal exercise.

The statement that the maximum oxygen intake level can only be measured using the multistage fitness test is false. Directly VO2max can be measured by measuring the oxygen intake while running  on a treadmill, which increases speed.
