What is indicated by the term "volitional fatigue" in the context of aerobic tests?

The term "volitional fatigue" refers to a state of fatigue that occurs when an athlete consciously decides to stop an activity or exercise, despite the physical ability to continue. In the context of aerobic tests, volitional fatigue is significant because it indicates that the individual has reached a point where they no longer wish to exert themselves, often due to perceived effort, discomfort, or mental fatigue, rather than an absolute physiological inability to continue.

This concept is critical when assessing an athlete’s performance, as it can highlight mental and emotional factors influencing the ability to endure physical challenges. Recognizing this form of fatigue helps distinguish between physiological limitations and an individual’s mental decision-making process regarding their effort levels.
