Abstract
Tennis serve performance is essential because high-quality serves increase the chance of winning points by reducing the opponent’s time to return accurately. This study aimed to compare the displacements of tennis serve between Hyeon Chung’s junior match in 2013 Wimbledon Open - Boys’ singles and himself as a professional player in 2018 to explore the difference according to expertise. Every frame was captured from a high-definition video, and tennis serve displacements were processed using a specialized written MATLAB program. It determined where the tennis serves landed on one of the T, Mid, or Wide sections in the service box. Chung’s serve as a junior player landed in the T section showed 23.95 %, whereas 46.3 % of a professional player’s serve appeared in the T section. More frequent serves to the T section were observed for experienced players, shortening its distance and placing it at the furthest distance from the opponent.
