Abstract: During an endurance run various physiological changes occur in response to the metabolic energy demands of the activity, and the runner makes continuous cognitive appraisals of the experience. The purpose of this investigation was to document the changes and relationships in several metabolic indices and cognitive appraisals that occur throughout a two-hour run. More specifically, 12 male competitive runners ran on a treadmill at approximately 70 percent of their maximal oxygen consumption for two hours. The metabolic indices assessed at specific times during the run were heart rate (HR), ventilation (Ve), respiratory quotient (RQ), plasma lactate (La) and plasma glucose (Glu). Simultaneously, cognitive appraisals of exertion (ratings of perceived exertion; Borg, 1962), expectancies (self-efficacy; Bandura, 1977), and affect (profile of mood states; McNair, Lorr, & Droppleman, 1971) were assessed.
