Method: five elite male finswimmers participated voluntarily in this study and all in the nationals top 3. Two digital video cameras (JVC, 120Hz) and APAS (Ariel Performance Analysis System) software were used to analyze the collected data, then, used the method of pair-sampling t-test in SPSS for windows 12.0 to analysis the differences between the two starts. Results: 1. The arch of foot standing posture and the sole of foot standing posture were significant differences in angle of attack, take-off velocity, take-off vertical velocity, take-off horizontal velocity, 15 meters velocity and flight distance(p<.05). By above parameters, the arch of foot standing posture is better than the sole of foot standing posture. 2. There were no significant differences between these two standing postures in take-off angle, entry angle, body inclination, entry velocity, entry vertical velocity and entry horizontal velocity. By above results, we can found these two standing postures have consistency, but the arch of foot standing posture have the better start velocity so it causes farther flight distance. Conclusion from the results: the arch of foot standing posture is better start movement.
