<p> The purpose of this study was to clarify the characteristics of the exercise intensity in a Rugby Sevens Game by a DLT method that measured the moving speed and the moving distance in a game and comparing with previous research of a Fifteens rugby game. No significant difference was observed between the average distance (1.45±0.15km) and the average speed (1.60±0.16m/s) of FW during a game and the average distance (1.48±0.14km) and the average speed (1.63±0.15m/s) of BK. There was also no significant difference between these parameters for each uniform number. From the analysis of six categories on the basis of the maximum speed in the game, it was estimated that about 10 seconds of middle/high-intensity exercise per in-play and out-play time and about 51 seconds of low/middle-intensity exercise including a rest period per in-play and out-play time were repeated during one game. These results showed that a Sevens rugby game has less specific characteristics in terms of position and is faster in terms of moving speed than a Fifteens rugby game. From the results of exercise intensity in this study, it was considered that the higher exercise intensity, the longer exercise time and the shorter rest time were needed in training for a Rugby Sevens Game than for a Fifteens rugby game.</p>
