What are the advantages and disadvantages of each of the methods calculating maximum oxygen intake

Responses will vary. A sample response follows: The three methods of measuring maximum oxygen intake are the multistage fitness test, the direct VO2 max measurement, and the estimated VO2 max. The multistage fitness test is useful because many people can do the test at once, and the results are reasonably accurate, although it can be difficult to find the audio equipment to play the beeps.

The estimated VO2 max is simple to find and doesn't require activity, but it is the least accurate method of determining maximum oxygen intake.
