We analyzed the movement of Stöckli on a pommel horse based on the data acquired with a motion capture system. The following results were obtained from the analysis. (1) The center of gravity moves around in a wider range in Stöckli than a double-leg circle. (2) Upper body muscles working in the performance of Stöckli are almost the same as a double-leg circle. However the activity level of muscles differs with each other in Triceps Brachii Caput Laterale which shows frequent steep peak in the performance of Stöckli . (3) An evaluation method using the Lissajous diagram generated by two harmonic oscillations of the body rotation and the hip rotation is useful for Stöckli.
