Abstract

The aim of this study was to compare the psychological and physiological responses of self-selected and imposed sessions of equivalent intensities and durations and allowing to participants a free control of pace during the self-selected session. Seventeen participants completed three sessions on a cycle ergometer. Participant's VO2Peak and lactate threshold were measured during an incremental exercise test. During the second and third sessions, participants could view a virtual cyclist on a monitor. During the self-selected session, participants were allowed free control of the intensity and duration. To ensure that the imposed session replicated the self-selected session in intensity, participants were instructed to follow an additional virtual cyclist, which was displayed on a monitor using the CompuTrainer 3D software. Power output and physiological and psychological variables were recorded during the sessions. A two-way ANOVA showed no effect of condition for power output (P=0.940), heart rate (HR) (P=0.965), VO2 (P=0.898), blood lactate (P=0.667), Feeling Scale (P=0.877), Felt Arousal Scale (P=0.924) and CR100 (P=0.939). A paired t-test showed no significant difference in Physical Activity Enjoyment Scale scores between sessions (P=0.054). In contrast to previous studies, the self-selected session did not provide better affective responses than the imposed session with same intensity and duration.
