Abstract
Together with other physiological responses, the neuromuscular fatigue mechanisms, and related perceptual responses, accompanying task failure are suggested to be dependent on the intensity domain within which exercise is sustained. Here, we show that peripheral fatigue demonstrates a high domain specificity, whereas such specificity is absent for central fatigue. Sensations of fatigue, pain, and breathlessness demonstrated intensity domain specificity and might have contributed to reaching maximal levels of RPE and, thus, task failure.
