The purpose of this study was to investigate the physical activities of referees during rugby games. Referees in 6 games (including 2 company games, 2 university games and 2 high school games) were filmed with 2 video tape recorder to estimate the distance and velocity using a DLT method. Accelerate phase and tum movement of referees were videotaped using another video tape recorder.
The results were summarized as follows:
(1) The mean time of out-of-play per a play was almost 30 second.
(2) The mean time of in-play per a play in high school games was almost 20 second.
(3) The longest total distance was 6567.4m in university games.
(4) Jogging (under 4m/sec.) shared the highest percentage of almost 90%.
(5) There were 286 times of accelerate phase in university games.
(6) There were 379 times of tum movement in high school games.
