When assessing VO2 max, what does a participant's request to stop imply?

When assessing VO2 max, a participant's request to stop indicates a potential health concern at the exertion level. This request often signifies that the individual may be experiencing excessive fatigue, discomfort, or distress associated with high-intensity exercise. It's essential to interpret this as a signal that the current level of exertion may be unsafe or unsustainable for the participant.

Monitoring participants during a VO2 max test is crucial, as individuals can vary widely in their responses to intense physical activity. If a participant feels the need to stop, it can reflect physiological limitations or risk factors that need to be taken seriously. Hence, recognizing this request is vital for ensuring the safety and well-being of the participant during the assessment process.
