目的:本研究以裁判「園、大、輕、正、美」的評分觀點及運動學角度，分析在三種鞍馬輔助器材上表現全旋動作之差異。方法:利用兩部60Hz的攝影機記錄13位國小男子體操選手在三種鞍馬輔助器材上的動作表現，再利用Studio 9.0影像編輯軟體剪接每一位受試者的表現，而後聘請四位國家級裁判 針對影像檔內容來進行評分，最後將實驗所得資料以one-wayANOV A來進 行按測，若達顯著水準時，再以LSD最小顯著差異進行事後比較。結果:在裁判評分中「園、大、正、美與總扣分」具顯著差異;在運動學方面，三種輔助器材上所表現的全旋其作用時間、躁關節高度、全旋半徑比值、全旋角速度及稅關節角度上皆具顯著差異。結論:本研究證實較低高度的輔助器材，促使選手能有較大的全旋半徑、較快的全旋角速度以及全旋時有較高的躁關節高度。

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