摘要

目的：瞭解不同技術層次排球選手預測不同舉球動作之勝算差異。方法：以二所大學之排球運動績優生及初級班學生共137名為參與者，依其對舉球動作之判斷，來測試其視覺預測能力，資料以廣義線性混合效應模型來分析。結果：運動績優生預測舉球動作勝算顯著高於一般生的情況為：一、年齡為「18－19歲」且為4號位舉球動作。二、年齡為「20歲以上」且為3號位舉球動作。三、碰球後之2、3、4號位舉球動作。結論：熟練者因較能利用重要的前線索，致使其在3、4號位舉球動作上有較優的預測能力。2號位舉球動作在碰球前與中時，因反方向舉球及快攻掩護之假動作較難預測，使得不同技能者間沒有顯著差異；在碰球後時，因已暴露舉球動作的意圖，使得熟練者有較優的預測能力。

Purpose: To understand difference of prediction odds in different setting up movements from volleyball players of different skill levels. Method: The study was designed to test visual prediction competence of total 137 students with high athletic performance and basic skills from two universities based on their judgment of setting up movements. The data gained was statistically analyzed in Generalized Linear Mixed Effects Model. Results: Students with high athletic performance had significantly higher prediction odds than students with basic skills in the following aspects: a. students aged 18-19 in setting up movement position 4. b. students aged over 20 in position 3. c. positions 2, 3 and 4 after touching the ball. Conclusions: Masters had better prediction ability in positions 3 and 4 of setting up movement because they could make better use of precue. Position 2 of setting up movement before and while touching the ball, since the false setting up movement of opposite direction and false movement of quick attack covering were harder to predict, so there existed no significant difference between students of different skill levels. Masters had better prediction ability only after touching the ball because their intentions of setting up movement had been exposed.
