The purpose of this study was to examine the characteristics of skill levels and phases for players to enhance the performance of straight course in short track speed skating. For the analysis, the events were classified into left touch down, right push-off end, right touch down, left push-off end and second left touch down and the phases were right push-off, right recovery, left push-off and left recovery. The subjects were 4 Korean elite woman short track skaters. The motion were analysed using the DLT(Direct Linear Transformation) method of three dimensional cinematography. The primary findings of this study were included as follows; 1. Comparing the temporal valuables of the skaters, it is desirable that push-off of right leg should be faster than that of left leg and recovery of right leg should be slower than that of left leg. 2. In gliding phase, it is recomended that the skaters try to decrease the propulsion angle which the other leg is in recovery to avoid the plantar flexion. 3. It was founded that the trunk angle was increased for the right stroke and decreased gradually while the left stroke, which could reduce the centrifugal force in the curve. 4. The knee angular velocity of the left leg should be increased gradually after the maximum knee angular velocity of the right leg, which could a positive effect on the push-off force on the ice surface. 5. After the push-off motion, the distance between both legs was greater in right push-off end than in left push-off end because players sould move inner course in right push-off. In addition this study analysed positionof center of mass and ankle angle and so on.
