Amplitude is an important aspect for performing circles on a pommel horse, but the ability to maintain such amplitude over the course of a long performance, say, over 10 seconds, has not been studied. This study provides pilot data for the ability to perform many circles and maintain amplitude. In all, 28 gymnasts performed as many circles as possible on a pommel horse while maintaining as great an amplitude as possible. Kinematic data were recorded using a Kinect set above the pommel horse, and the head–toe distance on a horizontal plane was computed as an amplitude variable. As a result, the average number of circles was 46; only 25% of participants were able to perform over 50 circles. Even for them, it was difficult to maintain amplitude after 50th repetitions, suggesting that 50 circles was a discriminative number for higher-level performance.
