摘要

目的：瞭解視覺偵察影片不同擊球時間點之信效度。方法：以北部某大學選修排球初級之男女同學共73名爲受試者，依其對2000年男子奧運排球冠軍隊攻擊球員中攻擊動作與攻擊落點之判斷，來測試受試者在三套不同擊球時間點影片中的視覺偵察能力，所得資料以廣義線性混合效應模式進行統計分析。結果：擊球前第六個畫面(180ms)、擊球中畫面及擊球後第二個畫面(60ms)之影片最具有信效度，而擊球前第九個畫面(270ms)、擊球中畫面及擊球後第三個畫面(90ms)影片之信效度亦可接受。結論：擊球前180ms、擊球中及擊球後60ms之影片顯示，由於擊球時間點與球路存在交互作用，球路之預測難度符合內容效度，使得在不同的擊球時間點下，球路預測難度存在邏輯性之差異。而球路預測難度之再測值符合再測信度，使得相同的球路在前後預測難度上是穩定的。因此其最具有信效度，將有利呈現最豐富的攻擊訊息，可供運動情境應用。

Purpose: This study was to understand the reliability and validity of different time points of hitting the balls in visual detection films. Method: The subjects were73 male and female students from a university in the north selecting basic volleyball skills. The study tested the subjects’ visual detection competence in different time points of hitting balls in three films based on their judgment of attack movements and falling points of attack by watching the attackers in the film of male volleyball champion of 2000 Olympic Games. The data gained was statistically analyzed in Generalized Linear Mixed Effects Model. Result: The following scenes had the highest reliability and validity: the 6(superscript th) scene of 180ms before hitting the ball, the scene of while hitting the ball and the 2(superscript nd) scene of 60ms after hitting the ball. Besides, the following scenes also had acceptable reliability and validity: the 9(superscript th) scene of 270ms before hitting the ball, the scene of while hitting the ball and the 3rd scene of 90ms after hitting the ball. Conclusion: The film of 180ms before hitting the ball, while hitting the ball and 60ms after hitting the ball showed that because of the interaction between time points of hitting the balls and ball paths, and difficulty of predicting ball paths corresponded to content validity, there existed logic differences in difficulty of predicting ball paths under different time points of hitting the ball. In addition, test-retest values of ball paths corresponded to test-retest reliability, so the predicting difficulty of the same ball paths in test-retest were stable. Therefore, the film had the highest reliability and validity in that it provided the most abundant offensive information to apply for sport situations.
