Rugby Tackle is an only method for defense to attack. It is necessary to clarify the motion during tackle to know effective tackle. The purpose of this study is to clarify the characteristics and difference of tackle motion among different competitive levels by analyzing tackle motion of rugby players belonging to high school, college, and professional. In this study, tackle form was especially investigated and compared. Subjects ran enough, landed on the force plate, and tackled on the tackle bag on which an acceleration sensor attached. Impulse of the tackle bag increased as the competitive level increase. The angle of truncus to direction greatly changed in professional players compared to high school and college players. The average angle of truncus to horizontal plane was smaller for the professional players at Foot Contact phase, almost same at Tackle phase, and bigger at Foot Off phase. Distance between stepping position and the tackle bag was longer for professional players. Therefore, it can be considered that professional players could change those truncus angles after Foot Contact.
