Abstract

[[abstract]]本研究的主要目的在探討不同羽球技能水準的受試者,在不同的 發球方式(正手、反手發球)及不同的視覺前線索時段下,預期羽球落 點的影響。本研究的受試者共計60名,並區分為高級羽球技能水準組 20名、中級羽球技能水準組20名、以及初級羽球技能水準組20名等三 組,分別觀看由一位高級羽球技能水準球員發球的影片,此影片係以 時間遮蔽法將畫面處理成為5種不同時段的視覺前線索畫面,共計100 個發球畫面。受試者在觀看完有限的發球動作畫面後,必須在2秒內 將該次發球的落點口頭告知在旁的研究者,然後將資料轉換成預期的 方向誤差率和深度誤差率,分別以三因子變異數分析及N-K 法事後比 較進行統計分析,以驗證假設。 研究結果發現,在預期的方向誤差率上結論為: 一、在正手發球的情況下,於時段1時,甲組球員的預期方向誤 差率低於其他兩組,顯示其在擷取視覺前線索訊息的能力上優於其他 兩組,至於其他時段裡則無差異。在反手發球的情況下,羽球技能水 準較高的運動員,在利用視覺前線索訊息的能力上,亦優於羽球技能 水準較低的運動員。 二、甲組球員、大學校隊與一般大學生,在時段1∼3時,正手 發球的方向誤差率均高於反手發球的方向誤差率。至於其他時段裡, 兩種發球方式則無差異。 在預期的深度誤差率上結論為: 一、甲組球員及一般大學生,反手發球的深度誤差率均高於正手 發球的深度誤差率。 二、在時段1、時段2及時段4時,反手發球的深度誤差率均高 於正手發球的深度誤差率,至於其他時段,兩種發球方式則無差異。 三、在時段2∼4裡,羽球技能水準較高的運動員,在預期發球 深度的能力上,要優於羽球技能水準較低的運動員。至於在其他時段 裡則無差異。 This study was mainly to explore how the subjects of different badminton skill levels would anticipate the shuttlecock's landing position under different serves (forehand serve and backhand serve) and different visual precue time periods. This study totally covered 60 subjects who had been equally divided into three groups : senior- level group (Group A), middle-level group (Group B) and primary-level group (Group C). Each subject should separately watch the film in which one senior- level player was serving a ball. This film had been processed into 5 different time periods visual precue by using the temporal occlusion method and had totally 100 pictures for serving a ball. The subjects should exactly speak out the landing position of that serve to the researcher at side within 2 seconds after watching the designated pictures for serving a ball. Then, the related data would be converted into the anticipated direction error and depth error which should be analyzed separately by three-way ANOVA and N-K method in order to verify the hypothesis. As the result of this study turned out that in the anticipated direction error, this had reached the following conclusions: 1.In the forehand serve circumstance, the anticipated direction error of the players from Group A was lower than the ones from the other two groups during time period one,indicating that Group A players' ability in picking the information of visual precue was superior to the other two groups in time period one. But, it maked no difference in other time periods. In the backhand serve circumstance, the players of higher-level badminton skill was also superior to the players of lower-level badminton skill in the ability of using the information of visual precue. 2.As to the players from Group A, the college representation team members and common college students, their forehand serve's direction error was higher than their backhand's during time period one to three. But, during other time periods, there was not found any difference between these two kinds of serves. In the anticipated depth error, the conclusions should be : 1.As to the players from Group A and common college students, their backhand serve's direction error were all higher than their forehand's. 2.During time period one, two and four, the backhand's depth errors were all superior to the forehand's. As to other time period, there seemed no difference between two kinds of serves. 3.During time period two to four, the players of higher-level badminton skill were superior to the ones of lower-level skill in the ability of anticipating the serve depth. As to other time periods, it had not found any difference. This study was mainly to explore how the subjects of different
