本研究旨在探討巧固球選手從事中樞騰空射網動作與兩側射網動作差異及射網成功率之比較。以苗栗縣教師男子巧固球代表隊十名運動員為研究對象，其身高為174 ± 3.66公分、體重為72 ± 5.04公斤、年齡為35.4 ± 1.25歲、球齡為21.9 ± 3.79 年。採用Panasonic DV攝影機及SONY數位相機拍攝選手的射網動作，從影片記錄20場練習比賽過程後，統計射門方式及成功率次數，以T–test考驗分析，得結果如下：
一、不同方向中樞射網與兩側射網動作出手水平與垂直角度有顯著差異(p<.05)。
二、不同方向中樞射網與兩側射網得分成功率及防守成功率有顯著差異(p<.05)。
三、不同方向射網估計可得分區域，兩側射網有效範圍、着地面積較優於中樞射網。
　　本研究結果發現，影響比賽勝負的關鍵，主要在射網成
功率，而非射網的總次數，同時射網成功率又以兩側騰空射網為主。

Abstract
　　The purpose of this study is to compare the differences and the successful rate between the central shootings and two-sided shootings of Tchoukball players. The subjects of this study are 10 players, whose stature is 174±3.66cm，weight is 72±5.04kg；age is 35.4±1.25 years，and experience on the Tchoukball game is 21.9±3.79 years.，Adopting the Pansonic DV and SONY digital camera to record the shootings of players in 20 practical games, using the T–test to account the times of shootings and the successful results as follow:
1. The horizontal vertical angel in different directions of
central and two-sided shootings results in the significant difference.p（p<.05）.
2.The successful rate of the goal and the defense in different directions of central and two-sided shootings results in the significant difference（p<.05）.
3. According the estimation of the effective range of the
goal in different directions of shootings, the two-sided one have the larger effective range and the larger area of the goal.
　　In this study, the critical factor of the game is the successful rate of shootings rather than total times of shootings. Meanwhile, the major factor of the successful rate of shootings is whether or not to take the two-sided shooting.
