A Study on the Exercise Intensity of Rugby Union Game by DLT Method
In this study, the movement distance and the movement speed of players were measured in the game by using the DLT method in order to clarify the characteristics of the exercise intensity of the university rugby union game. The total movement distance and the average movement speed of BK (5.16±0.48km,1.13±6.26m/s) were higher than those of FW (6.23±0.33km,0.94±8.92m/s), respectively. In addition, these values were significantly high at the positions where the players were located in the back row. From the movement distance and the movement speed in both the in-play and the out-of-play times, it was estimated that the middle-high intensity exercise of about 6 seconds and the low intensity exercise including 80 seconds rest were repeatedly performed in the game.
These results indicate that the training effect of rugby will be expected by : 1) Exercise intensity is set by the middle-high intensity exercise in the in-play time. 2) Exercise time is set by the time of the middle-high intensity exercise in the in-play time. 3) Rest time is set by the total of the low intensity time in the in-play and the out-of-play times in the game.
