Abstract: The purpose of this study was to compare three passive attentional manipulations on ratings of perceived exertion (RPE) during exercise. College subjects (13 men, 11 women) completed four 20-min. periods of cycling at 70% of peak aerobic power. Four stimulus conditions were randomly assigned from auditory (listening to fast upbeat music), visual (viewing high-action videotape of human stunts), auditory/visual (both stimulations), and control (no stimulation), Heart rate, peripheral RPE, central RPE, and over-all RPE were measured at 5-min. intervals. Peripheral RPE was significantly higher for visual at 5 and 20 min. compared with auditory/visual and at 5 min. compared to auditory stimulation. Central RPE was significantly higher for visual stimulation at 5, 10, 15, and 20 min. compared with auditory/visual, at 5, 10, and 20 min. compared with auditory, and at 5 min. compared to the control condition. Over-all RPE was significantly higher for visual stimulation at 5, 10, 15, and 20 min. compared with auditory/visual and at 5 and 10 min. compared with auditory stimulation. Passive dissociations using high-action visual images may evoke a strong, emotional response which may heighten awareness of physical sensations.
