This study was conducted to investigate the effects of the core exercise program on tennis performance in tennis players. The study included a total of 31 male tennis players of 13-16 years of age who were at least 2 years of sports age. The tennis players were randomly divided into two different groups as the 1st group (exercise = 16; core exercise + tennis technical training) and the 2nd group (control = 15; tennis technical training). The participants involved in the study were evaluated 8 weeks before and after the exercise. During the performance assessment, long jumping, hand capability, flamingo balance, seating-long flexibility and mocking tests were performed. The "Shapiro-Wilk" test was performed with examples of graphic approaches and normality tests for normal distribution compatibility of data. To compare all the parameters between the two group average, the "Independent Sample T Test" was performed with the "Paired Sample T Test" in the analysis of repeated variables to determine the effects of time (pre-exercise - post) in group comparisons. The limit value for statistical significance was determined by 0.05-0.01 p. The study resulted in a significant difference in the flamingo balance test in the experiment and control group (p<0,05 - p<0,01). The core post-training experimental group was found to have a significant increase in the average post-training parameters in the long jumping, hand capability, seating-long flexibility and post-training parameters (p<0,01). As a result, core exercise programs can be said to have an impact on tennis performance.
