Laboratory Determination Of Maximum Oxygen Consumption. Do We Actually Test The Maximum Values?
Vol.12,No.1(2018)
The main aim of this article is to enhance the readers interest in the current state of determination of
maximum oxygen consumption, an issue that is still current. Scientists are constantly discussing the testing protocol design. We wanted to provide not only an objective view on the concept of the testing protocol, but also we wanted to have a keen interest in validity criteria of maximum oxygen consumption. In general, VO2 changes ≤ 150 ml/min between two consecutive stages is still considered as the primary criteria. On the other hand, we can also find stricter values of VO2 changes ≤ 50–100 ml/min in scientific literature. In addition to this, the secondary criteria is often used for respiratory exchange ratio ≥ 1.15 and reached ≥ 90 % age predicted maximum heart rate). Subsequently, recent evidence suggests that using a verification phase is a valid tool for the scientist (verification phase usually starts until 20 minutes after the completion of the progressive test). This article is not a meta-analysis. The article provides basic information about the field of performance diagnostics. Key aspects of valid VO2max criteria are that they should be objective and specific to the subject.
