Undergraduates scoring low and high on a questionnaire measure of relatively extended fatigue were presented four versions of an auditory mental arithmetic challenge, ranging in difficulty from low to impossibly high. Among Low Fatigue participants, blood pressure and heart rate responses assessed during the work periods first rose and then fell with difficulty. Among High Fatigue participants, blood pressure responses remained low across difficulty conditions, while heart rate responses rose weakly from the low- to the moderate difficulty condition and then declined. Findings are discussed in terms of a recent interactional analysis of fatigue influence on cardiovascular response.
Research highlights
► Low- & high extended fatigue participants perform low to impossible difficulty tasks.
► Low Fatigue participants’ SBP responses rose then fell with difficulty.
► High Fatigue participants’ SBP responses remained low across difficulty.
► High and Low Fatigue participants had low SBP responses during impossible task.
► DBP and HR response demonstrated similar results.
