Abstract

The study aimed to investigate the effects of an acute exercise bout on urges to eat chocolate, affect, and psychological and physiological responses to stress and a chocolate cue. Following 3 days of chocolate abstinence, 25 regular chocolate eaters, took part, on separate days, in two randomly ordered conditions, in a within-subject design: a 15-min brisk semi-self-paced brisk walk or a passive control. Following each, participants completed two tasks: the Stroop colour-word interference task, and unwrapping and handling a chocolate bar. Chocolate urges [State Food Cravings Questionnaire (FCQ-S); Rodríguez, S., Fernández, M. C., Cepeda-Benito, A., & Vila, J. (2005). Subjective and physiological reactivity to chocolate images in high and low chocolate cravers. Biological Psychology, 70, 9-18], affective activation [Felt Arousal Scale; Svebak, S., & Murgatroyd, S. (1985). Metamotivational dominance: a multimethod validation of reversal theory constructs. Journal of Perception and Social Psychology, 48, 107-116], affective pleasure/valence [Feelings Scale; Hardy, C. J., & Rejeski, W. J. (1989). Not what, but how one feels: the measurement of affect during exercise. Journal of Sport and Exercise Psychology, 11, 304-317], and systolic/diastolic blood pressure (SBP/DBP) were assessed throughout. Exercise reduced chocolate urges and there was a trend towards attenuated urges in response to the chocolate cue. Exercise also attenuated SBP/DBP increases in response to the stressor and chocolate cue. The effects on urges varied across the dimensions of the FCQ-S.
