Effects of an exercise program with audiovisual stimuli on affective mechanisms and future physical activity: a randomized controlled trial

Résumé

This study examined whether audiovisual stimuli influence affective valence (pleasure vs. displeasure), affective mechanisms (e.g., automatic affective valuation, exercise enjoyment), and future physical activity (PA) as a function of a 4-week exercise intervention. Sixty-one participants (55 females and 6 males) were randomly assigned to an audiovisual (watched and listened to self-selected audiovisual stimuli during exercise) or control group (without audiovisual stimuli) and completed 20-minute aerobic exercise sessions three times a week for four weeks. Affective valence and affective mechanisms were assessed at baseline, mid-intervention, end-of-intervention, and future PA engagement was evaluated one month post-intervention. Linear mixed models revealed that the audiovisual group had improved affective valence (p < 0.01) and exercise enjoyment (p = 0.02) during the 4-week exercise intervention compared to the control group (p < 0.01). A parallel-process latent growth curve model indicated that the initial level of automatic affective valuation was a predictor of the initial level of exercise enjoyment (p < 0.01), and positive changes in automatic affective valuation predicted better exercise enjoyment (p < 0.05) independent of the group. Affective valence directly predicted future PA (β = 0.44) and indirectly predicted future PA through automatic affective valuation and exercise enjoyment, respectively (β = 0.53). Results indicate that affective valence predicts future PA. Our findings, therefore, contribute to the growing body of evidence that hedonic responses evoked by audiovisual stimuli can positively influence lifestyle behaviours (i.e., PA) that are important for maintaining and improving health.
