The purpose of this study is to show objective data about the amount of the activity of the referee in an actual game, and to use these for the referee training in the future. As a result of consideration, the main referee became clear that an equal ability of moved distance, the movement speed, and the turn frequency, etc. with the field player was demanded. The main referee showed total moved distance twice the sub?referee, and this moved distance was almost equal to the field player. Moreover, it has been understood that a considerably high ability is demanded from the main referee about brilliant because the frequency about four times the sub?referee of the turn is done. Therefore, the main referee is doing advanced work of giving a decision while equal stamina's with the field player being demanded and repeating the turn and the movement according to a diagonal method. On the other hand, the moved distance of the sub?referee was main referee and field player's halves. Moreover, it is thought that the sub?referee is giving the judgment (offside and ball out) in the stopped state at the moment from low?speed movement frequency high. The future tasks are to analyze the accuracy of the work of the sub?referee by comparing sub?referee's position with the position of an offside line, and to consider the sub ?referee qualitatively.

The purpose of this study was to make clear what affects the running speed of a player in a game. This research made the game of soccer of two games a research object. Two games of these were Japan versus UAE and Sanfrecce Hiroshima versus Yokohama Marinos. The method of calculating the amount of the activity used three dimensions DLT method. First of all, it takes a picture to install the entire pitch from the main stand rooftop in the competition site on each camera in two video cameras and this image is capture in PC every 1/3 seconds. And, the three?dimensional image analysis software was used, digitized, player's movement and the ball were converted into objective positional coordinates, and the amount of the activity was calculated on coordinate data. The following results were obtained by analyzing these data. In the J league game, the average speed of the ball was 6.04±6.26m/sec in the first half, and 6.23±5.52m/sec in the second half. In the game Japan versus UAE, the average speed of the ball was 6.11±6.29 in the first half, and 5.12±6.56 in the second half. The change of the average running speed of the field players of a team was highly affected by the change of the ball speed from both 2games.
