桌球反手切球技術動作分析－以大專男子選手為例

本研究目的在探討分析桌球反手切球技術動作，編製桌球反手切球技術動作觀察表並建立測驗的品質。研究對象：大專男子甲、乙組各六名選手，分別各五位右手、一位左手。研究方法：利用IPhone 6S錄製反手切球時的動作，再分解成每秒10張圖片，從圖片中擷取反手切球的六個階段：一、預備動作。二、引拍動作。三、擊球前動作。四、擊球動作。五、擊球後動作。六、還原動作。由五位評分者觀察評分。資料處理利用FACETS 3.67.1估計。研究結果如下：一、編製完成具有邏輯效度的反手切球技術觀察表。二、選手層面Rasch個別信度為.99非常優異，具有鑑別效度及代表性，證明本研究的選手測量有效。三、評分者層面評分一致性度為60.8%，表示評分有高低差異，但樣本具有代表性。四、組別層面Rasch個別信度.99非常優異，具有鑑別效度及外在效度。最後結論是成功編製桌球反手切球技術動作觀察表，並且有良好的測驗品質。

The purpose of this study was to analyze the technical movement of the back-hand-cutting of the table tennis, and to prepare a scale of technical observations of the backhand-cutting of table tennis and to constructthe quality of the test. The research objects were12 players of the table tennis players of colleges, including 10 right-hand players and 2 left-hand players. The research method was recorded backhand-cutting action by iPhone 6S and then decompose into 10 pictures per second. Capture the backhand-cutting from the picture in six stages: First, preparing stage. Second, the cue action stage. Third, hit the ball before the action stage. Fourth, hit the ball stage. Fifth, following action. Six, restore action. The score wereobserved by five raters. Data pro-cessing was estimated using FACETS 3.67.1. The results of the study were as follows: First, prepared an effectiveanalysis Scale of the backhand-cutting of table tennis. Sec-ond, the player level Rasch's individual reliability is .99, which is very good, with dis-criminant validity and representativeness. It proved that the player's measurement of this study is effective. Third, the grader-level scores were poorly rater consistency, with high and low scores, but the samples were representative, with a consistency of 60.8% among the scorers. Fourth,Rasch's individual reliability at the group level is 99. It is Excellent with discriminant validity and external validity. The final conclusionwas that the Scale of the backhand-cutting of table tennishadbeen successfully prepared. It hadgood test quality.
