羽球反手拍發球不同時間遮蔽對羽球運動員預期準確率之研究

本研究目在探討發球區域、技能水準及時間遮蔽對羽球雙打反手拍發球落點預期準確率之影響。採實驗研究法，將發球影片剪輯成不同時間遮蔽並編製成測驗影帶進行施測。受試者專家組10名，(平均年齡21.1±1.51歲)；生手組10名，(平均年齡21.2±1.4歲)。以發球區域(左、右發球區)、技能水準（專家組、生手組）及時間遮蔽時段為自變項，預期發球落點準確率為依變項，所得資料採三因子混合設計變異數分析進行假設檢定，顯著水準(α)定為.05。本研究範圍內所得的結果顯示專家組平均預期準確率為63.25%，生手組為48.16%；右發球區預期準確率為61.63%，左發球區為49.78%；三因子混合實驗設計交互作用未達顯著水準，各項二因子交互作用也未達顯著水準，各因子間主要效果的分析發現：(1)專家組的預期準確率優於生手組。(2)面對右發球區情境的預期準確率優於左發球區。(3)羽球發球關鍵訊息出現的時段在球拍觸球前66毫秒至觸球後33毫秒之間。

The purpose of the study is to investigate the anticipation accuracy of badminton backhand serve affected by service areas, skill levels, and time obstructions. The study used actual badminton videos and edited it into five types by various time obstructions. They are 99ms before stroke, 66ms before stroke, 33ms before stroke, the moment of stroke, and 33ms after stroke. The subjects are two groups. One group is ten professional badminton players, their average age is 21.1±1.51. Another group is ten beginners, their average age is 21.2. The experiment is analyzed by three-way ANOVA, significance level was set as α=.05. Conclusions of the study are (1) the average anticipation accuracy of professional badminton players team is more excellent than the beginners team in five various time obstructions types. (2) the average anticipation accuracy of right service area is better than left service area. (3) the crucial clues of backhand serve shows up at 66ms before stroke, 33ms before stroke, and the moment of stroke.
