This is the mental fatigue susceptibility ranking portion of a study seeking to determine metabolic biomarkers for resistance to fatigue. A total of 23 paid subjects completed a fatigue protocol involving informed consent, medical screening, Tuesday and Wednesday evening training on cognitive tasks, providing five urine samples (beginning with a Friday morning baseline), refresher training, and an experimental session (with six, four hour long blocks) starting Friday evening.
