The Purpose of this study was to set a virtual overtaking space in a curve-straight transition section and to analyze the skater"s skating motion in the overtaking situation and provide data on skating strategies that can be effectively overtaken in this section. The study included five male short track speed skaters (mean height, 1.72 ± 0.07 m; mean weight, 65.8 ± 2.8 kg; years, 23.6 ± 3.8 yrs)were analyzed. Data were collected from middle of the curve to the 7 m of the straight section and recorded using five digital SONY FDR-AXP35 video cameras (SONY, Japan) operating at a sampling frequency of 60 fields/sec and shutter speed of 1/500 sec. For each film frame, the joint positions were digitized using the KWON3D motion analyzer. Position data were filtered with low-pass Butterworth 4th order at the cut-off frequency of 7.4 Hz. The results of the study showed that the faster the transition section, the more deviates f rom the course, and CMH to be higher. There were two patterns of increasing or decreasing speed when passing the target, and when the speed increased, the ratio of the y-axis distance was large. Therefore, the effective in-course overtaking defined in this study should have a small distance between the inner line and the gliding foot at the middle of the curve(MC) and at the end of the curve(EC). And we concluded that the pattern that the lateral movement range (X) in the course is small and the velocity increases in the direction of motion (Y) is advantageous to pass the target at high speed.
