Abstract: The purpose of this study was to investigate to find some efficient teaching methods of Flip turn. Experiment was taken by means of electromyographical survey. Motions during flip turn were analyzed by means of making EMG of flip turns to be synchronized with the pictures of flip turn. Subjects were 7 male swimmers as expert group and 8 male college students as none-expert group, were participated in this experiment. The findings appeared to warrant the following conclusions: 1) It appeared to be 2 kinds of body rotation during flip turn of swimmers. One is vertical-axis rotation and another was horizontal-axis rotation. In the case of students, those rotations were overlapped each other. 2) In the case of Swimmers, a slight dolphin kick during the last armstroke of flip turn was appeared. But, such kind of kick has not seen during flip turn in the case of student. 3) Before foot touching the wall, swimmers showed a tendency to sink their upper body to the depth of space foot touch on the wall with their palms pushing the water directing to the bottom of pool as an opportunity to start roll the body. In the case of students, such kind of actions did not appear. Therefore, it was desired that 2 kinds of body rotation should be taught individually, when teaching the flip turn to student. And after recognizing vertical rotation and horizontal rotation of stability, it is required to combine those body rotations. After those instructions, it is better to get started to use a slight dolphin kick before vertical-axisrotation.
