The purpose of this study is to investigate the relationship between vividness of mental imagery and effectiveness of image training for sport performance. Seventy four university students (30 males, 44 females) were participated in this research. The subjects were randomly divided into the control group and the experimental group. Moreover, both the control group and the experimental group were asked to answer the vividness of mental imagery questionnaires (Nishida, 1981). Then, they were divided into high image group and low image group according to the median score of mental imagery questionnaires. The subjects who were in the experimental groups were participated in the image training programs. On the other hand, the subjects who were in the control groups were not participated in the image training program. All subjects were participated in the experiments ‘Foot Back’ to evaluate the effects of the image training and the performance levels. The results of two-way layout ANOVA (high image control, low image control, high image experimental, low image experimental × pre, post) showed that the main effect was found both control group and experimental group. The result of this analysis means that effectiveness of image training could not always effective to the performance level. The result also showed that the relationship between vividness of mental imagery and effectiveness of image training could not find in this experiment. However the subjects of high vividness of mental imagery group showed high sport performance before image training. This study concluded that high vividness of mental imagery is something related high sport performance.
