The effect of direct video feedback on the accuracy of tennis serve / Ruhil Amal Razali

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 lm square area adjacent to the service box T. Time series design was used in the study as part of the analysis of the data. The results showed that the test on Day 4 had significantly higher accuracy than intervention day (Day 3). Specifically, the results suggest that when video feedback was given on Day 3, the accuracy of the serve improved on the next day (Day 4). The implication of these findings is that it is a good tool to use the direct video feedback as a way to enhance technique execution in serve.
