The study used SPSS 20.0 statistical program with data of 316 middle and high school players participating in the 36th national student tennis tournament. It is concluded. First, there were no differences in analysis based on gender among background variables, while there were some differences in analysis based on levels of schools. Second, the effects of sport performance strategy and emotion change were influenced by perfectionism. Third, the effects of emotion change were partially influenced by sport performance strategy. The current findings suggest that individual function of perfectionism factors may be re-categorized.
