Scholarcy highlights

  • Mental fatigue reflects a change in psychobiological state, caused by prolonged periods of demanding cognitive activity
  • It has been well documented that mental fatigue impairs cognitive performance; more recently, it has been demonstrated that endurance performance is impaired by mental fatigue
  • It has been suggested that the negative impact of mental fatigue on endurance performance is primarily mediated by the greater perception of effort experienced by mentally fatigued participants
  • Pageaux et al first proposed that prolonged performance of a demanding cognitive task increases cerebral adenosine accumulation and that this accumulation may lead to the higher perception of effort experienced during subsequent endurance performance
  • The role of extracellular adenosine in chemical neurotransmission in the hippocampus and basal ganglia: pharmacological and clinical aspects
