This study aimed to develop a scale of designated images about the triangle and the circle for college football players. The study used a questionnaire answered by 369 students and the data collected was subjected to exploratory factor analysis, confirmatory factor analysis and reliability analysis. The resulting scale comprised two factors : a triangle image and a circle image. Each factor was measured on three subscales : physical activity, evaluation in physical activity and potency in physical activity. The scale had sufficient reliability, and we provided suggestions about the use of this scale. In addition, the result indicated that the triangle image evoked more negative perceptions and these were opposite to those evoked by the circle image. Further, the circle image was emphasized by the triangle image.
