Reliability
Reliability would depend upon how strict the test is conducted and the individual’ s level of motivation to perform the test. As the audiotapes may stretch over time, the tapes need to be calibrated – which involves timing a one-minute interval and adjusting the distance between markers. The recording is also available on compact disc, which does not require calibration.
Validity
There are published VO2max score equivalents for each level reached and the correlation to actual VO2max is high.
