摘　　要：Background:Core affect is defined as the most general affective construct consciously accessible that is experienced constantly.It can be experienced as free-floating(mood)or related to prototypical emotional episodes.The aim of this study was to examine the influence of pleasant and unpleasant core affect on cyclo-ergometer endurance performance.Specifically,we considered the influence of pleasant and unpleasant core affect on performance outcomes(i.e.,time to task completion)and rate of perceived exertion(RPE;Borg Scale,category ratio-10)collected during the task.Methods:Thirty-one participants aged 20-28 years were recruited.Core affect was randomly elicited by 2 sets of pleasant and unpleasant pictures chosen from the international affective picture system.Pictures were displayed to participants during a cyclo-ergometer performance in 2 days in a counterbalanced order.RPE was collected every minute to detect volunteers’exhaustion.Results:The study sample was split into 2 groups.Group 1 comprised participants who performed better with pleasant core affect,whereas Group 2 included participants who performed better with unpleasant core affect.Mixed between-within subjects analysis of variance revealed a significant 2(group)×2(condition)×5(isotime)interaction(p=0.002,ηp^2=0.158).Post hoc comparisons showed that participants who obtained better performance with pleasant core affect(pleasant pictures;Group 1)reported lower RPE values at 75%of time to exhaustion in a pleasant core affect condition compared to an unpleasant core affect condition.On the other hand,participants who obtained better performance with unpleasant core affect(unpleasant pictures;Group 2)reported lower RPE values at 75%and 100%of time to exhaustion in an unpleasant core affect condition.Conclusion:Findings suggest differential effects of pleasant and unpleasant core affect on performance.Moreover,core affect was found to influence perceived exertion and performance according to participants’preferences for pleasant or unpleasant core a
