This study was to quantitatively investigate the ball’s impact position and the ball-to-body tilt angle according to success (center and sideline) and failure in the tennis serve motion. For five tennis players of the Jeju Tennis Association, the flat serve motion was continuously attempted at the centerline (T-line) and the sideline (W-line) five times, respectively, super-high-speed video of 240 fps was taken. Variables (ball impact height, front and rear distance, whole body inclination angle, incidence angle) were calculated for this image using the Dartfish analyzer program. As a result of the study, it was found that there was no significant difference in all variables according to the success and failure of serving five tennis players. However, in the results, according to the characteristics of each individual, it was found that the higher the impact height of the ball, the higher the serve success rate. Also, it can be seen that the probability of success is higher when the ball is placed in front. This explains that athletes who show a statistically significant level in each variable during serving are more likely to need or improve their posture. Therefore, this study data suggests that tennis players, coaches, and related researchers can easily create serve models that can successfully serve and apply them in the field. Also, research on players with high skill in serve-skills can be more reliable data, and it is thought that it is necessary to verify various variables through three-dimensional analysis rather than two-dimensional analysis.
