Abstract
The consideration of the end-point of exercise (teleoanticipation) may influence fatigue development. This study examined the effect of expected exercise duration on physiological and psychological variables. 20 male cyclists participated in a graded maximal aerobic cycling test and two 20 minute cycling bouts. Participants expected to cycle for 20 minutes for the first bout (20 MIN), and for 40 minutes for the second (40 MIN) VO, was higher at 2 minutes and lower at 17 minutes in the 40 MIN condition. RPE was lower throughout the 40 MIN condition. Following initial analyses, participants were separated into intensity groups based on whether they exercised above RER=l.00 at any time during either cycling bout. RPE was lower for 40 MIN in the lower intensity group only. Results suggest that teleoanticipation alters both physiological and psychological variables via separate mechanisms that may be intensity-dependent.
