Abstract

The purpose of this study was to clarify the transition of playing time in tennis. To analyze about playing time in tennis, we use the computerized scorebook for tennis developed by the authors. Six matches, men's singles final of Wimbledon held in 1980,1981,1993,1994,2004 and 2005 were analyzed. The results about the transition of playing time in Wimbledon men's final were obtained as follows. Time duration per point was longest on 2000s (3.99 + 4.00 sec), and was shortest on 1990s (2.70 + 3.22 sec). Rally length was also longest on 2000s (4.1 + 3.0 shots), and was shortest on 1990s (3.0 + 2.1 shots). The inter-point time was shortest on 2000s (19.10 + 4.83 sec). These results showed that playing time became longer and rest time became shorter on 2000s matches. Players' physical ability was highly required on 2000s matches. The time duration of lst service shot was shortest on 1990s (0.69 + 0.07 sec). The time duration of ground stroke shot was shortest on 2000s (1.34 + 0.31 see). First service shot became faster from 1980s to 1990s, ground stroke shot became faster from 1990s to 2000s. These results were based on the changes of rule (e. g. ball regulation, inter-time rule) , the innovaion of racket technologies and the changes of players' play-style. The computerized scorebook developed by the authors was able to analyze about playing time in tennis.

Key Words: time duration of point, inter-point time, time duration of shot
