The impact of mental fatigue on a preloaded cycling-time trial in the heat
Journal Title: Journal of Science and Cycling - Year 2016, Vol 5, Issue 2
Abstract
Mental fatigue is a change in psychobiological state caused by prolonged periods of demanding cognitive activity and has been observed to decrease whole-body endurance performance [1-5]. Recently a decreased resting-state cerebral blood-flow in the fronto-parietal cortex in the heat compared to in thermoneutral temperature was observed [6], raising the question whether mental fatigue may be even more detrimental for wholebody endurance performance in the heat. In normal ambient temperatures, performancedecrements of 5% [2] and 2% [4] have been observed in self-paced time trials (TT) due to mental fatigue.
