The purpose of this research was to examine the hypothesis that feminine-typed females who process exercise-related physiological changes via affective schema overreact to the actual intensity of work. The design involved two groups of women, 20 in each group, who were feminine-typed on the Personal Attributes Questionnaire. One group was shown an intolerant model prior to a bicycle ergo-meter ride, whereas the second group viewed a tolerant model. Results revealed that those females in the intolerant condition experienced negative affect prior to the task, a set that resulted in higher RPEs during ergometry performance when compared to those in the tolerant condition. The data are discussed from the perspective of a parallel processing model of pain and their practical implications for exercise and sport.
