Purpose: Purpose of this study was to investigate which assistant equipments was most suitable for novice gymnasts to perform circles. Methods: Thirteen gymnasts were asked to perform 5 circles on three small pommel horse of the assistant equipment. A three-dimensional motion capture system with sampling frequency 60Hz was used to record each gymnast's performance. One-way ANOVA with LSD post-multiple comparisons was used to exam inter-group differences. Significant level was set at α<.05. Results: In judge's assessment domain, the judge's principles ”roundness, amplitude, no deviation, aesthetics and average of sun of deduction points” showed significant difference among the 3 assistant equipments. In terms of kinematics, the duration, height of ankle, radius of circles of rate, angular velocity of circle, and hip angle were significantly different among the 3 assistant equipments. Conclusion: This study found that gymnast performing on the lower assistant equipment, they appeared larger radius, short duration, faster angular velocity of circle movement.
