Aim: Health-behavioral research has been focused on the influence of physical activity on affect, mood, and emotion (Ekkekakis, 2013). In the current study, we examined the influence of core affect on cycleergometer endurance performance. Methods: Participants were 10 sport science students, aged from 20 to 28 years. Core affect was randomly elicited by two sets of pictures, one positive and another negative, chosen from the International Affective Picture System (IAPS, Lang et al., 2008), during cycle-ergometer performance. In a preliminary visit, participants rated the pictures in terms of affective valence, arousal, and dominance and undertook a ventilatory threshold assessment. Afterward, pictures were shown to the participants during their performance. ECG was continuously recorded before, during, and after performance using a Bioharness (Zephyr technology), in order to assess the influence of positive and negative pictures on HRV and related parameters (e.g. HF, LF). Scores of perceived effort (Borg scale, CR-10) and ratings of arousal and hedonic tone (affect grid) were collected every minute during performance. Results: Core affect elicited idiosyncratic responses that resulted in different performance effects. Compared to positive pictures, negative pictures had a positive effect on time spent on the cycle-ergometer mainly in unfit participants, likely because of their impact on HF parameter. In contrast, positive pictures had beneficial effects on fit participants. Furthermore, negative pictures exerted a stronger impact on hedonic valence intensity in both groups of participants. Conclusions: In summary, positive and negative core affect was found to exert beneficial effects on cycle-ergometer endurance performance as a function of the physical fitness level.

Abstract
Aim: Health-behavioral research has been focused on the influence of physical activity on affect, mood, and emotion (Ekkekakis, 2013). In the current study, we examined the influence of core affect on cycleergometer endurance performance. Methods: Participants were 10 sport science students, aged from 20 to 28 years. Core affect was randomly elicited by two sets of pictures, one positive and another negative, chosen from the International Affective Picture System (IAPS, Lang et al., 2008), during cycle-ergometer performance.
