The purpose of this study was to examine if junior tennis players could improve their speed and accuracy of the serve by using direct video feedback. Ten intermediate junior tennis players completed 50 acceptable maximum effort serves, aiming to land the ball within a 1 m square area adjacent to the service box T-area. Time series design was used in the study as part of the analysis of the data. The results showed that when video feedback was given on test day 3, the accuracy of the serve improved on test day 4. Additionally more accurate services and more "acceptable" services were completed in the square. The implication of these findings is that direct video feedback is a good tool to use to enhance technique execution of the serve.
