摘要

背景：扯鈴中的拋接多鈴動作，在表演或比賽中常是觀眾注目、獲得高分的來源。拋接鈴的動作，隨著鈴數的增加，難度也跟著提高。學習拋接扯鈴的動作，往往從單鈴開始，再隨著拋接少鈴的成功，逐漸增加鈴數。然而在拋接不同數量的鈴時，其動作型態的特性為何？少鈴與多鈴之間是否有關連性？目的：探討單鈴繞腿、雙鈴繞腿以及雙鈴等三種不同拋接扯鈴動作型態之差異。方法：具一年以上扯鈴經驗之國中體育班八名學生參與實驗。以雙鈴、單鈴繞腿和雙鈴繞腿之順序，利用高速攝機拍攝三種動作影片，再以Kwon3D進行影片數據化，擷取運動學資料。導出之動作型態資料分別以單因子、雙因子重複量數變異數分析與卡方檢定，進行統計檢定。結果：三種拋接鈴動作的週期、兩手相對相位、鈴的滯空時間，及手與鈴的相對相位達顯著差異。結論：鈴線上的鈴數除了會影響雙手協調的週期與頻率外，一個鈴與兩個鈴的差別在於鈴與手間的時宜。未來將進一步探討三鈴以上的動作，以增加了解拋接不同數量扯鈴的動作特性，希望可以提供指導者設計課程、提供學習者回饋的相關訊息。

Diabolo juggling has always been an eye-catching performance and was often awarded high points in competitions. The difficulty of performing the diabolo juggling increases with the number of diabolo juggled. Therefore, beginners usually start from learning to juggle one diabolo then increasing the number of diabolo after acquiring the single diabolo juggling skill. However, little was known about the difference in movement between different numbers of diabolo juggled, as well as the reason why learning to juggle fewer diabolos would help to learn to juggle more diabolos. The purpose of the study was to investigate the movement characteristics of 3 kinds of diabolo juggling patterns: single diabolo around-the-foot orbits, double diabolo around-the-foot orbits, and double diabolo juggling. There were 8 eighth graders who had at least one year's experience in diabolo spinning participated in the study. All the participants performed 3 diabolo juggling tasks in the following sequence: double diabolo juggling, single diabolo around-the-foot orbits, and double diabolo around-the-foot orbits. A high speed video camera was used to video tape the frontal view of the juggling movement, and the Kwon3D digitizing system was used to capture the kinematics of the left and right sticks and the center of the diabolo. One way, two way repeated measure ANOVA, and the Chi-Square test were used for statistical analyses. The results showed that the movement period, the relative phase of the two sticks (hands), air time of the diabolo, and the relative phase of the stick and the diabolo had significant differences among the 3 kinds of juggling pattern. In conclusion, the number of diabolo juggled, not only affects the period and frequency of the bimanual movement, but also influences the timing between the diabolo and hand-stick movement. Future study will examine the movement characteristics of juggling 3 and more diabolos in order to better understand the relation between the number of diabolo and the movement characteristics in diabolo juggling.
