| Summary: | 博士 === 國立臺灣師範大學 === 體育學系 === 105 === The periodic relations between ball and bat in table tennis may represent timing performance that is tied closely to the result of each point in competition, and demonstrates the speed-accuracy tradeoff inherent in interceptive actions. The novel way of measuring timing performance on table tennis drive was first introduced by Chuang and Liu (2017), the method, however, has not yet been extensively explored. While most of literatures on table tennis drive treat only in block practice condition, there have been few attempts to establish a direct relationship between ball and bat in terms of timing performance. The purpose of practice and drills is to win the games. Therefore, it is important to identify the data collected in the practice condition can reflect the game situation. In addition, the application value of the timing performance may be significantly increased if a trained analyst can use the video recorded from a 30 fps camera to analyze the timing performance instead of using movement data derived from the multiple high-speed camera system. The propose of this study was therefore threefold: (1) examining the performance of the table tennis drive in the controlled laboratory condition; (2) examining the performance of the players in simulated table tennis matches; and (3) comparing timing performance derived from high-speed cameras (200fps) and 30-fps camera. Ten advanced and ten intermediate table tennis players were recruited from universities and performed forehand and backhand table tennis drives under normal drill conditions followed by a simulated match play. The high-speed-cameras system and a 30 fps camera were used for data collections. The results showed the significant difference on driving performance from player levels and approaching ball characteristics. The differences between drill and matches indicated the task requirement and experience effects. Finally, data collected from the 30-fps camera provided suitable basis for analyzing timing performance. The study demonstrated a promising way to measure timing performance, and established appropriate procedure for testing in drills and matches. Results of sport science research should be further tested in both drills and matches in order to offer applied knowledge for researchers, PE teachers, coaches and athletes.
