足球比賽中射門技術之研究~以2010年東亞杯資格賽為例~

本研究目的乃針對2010年東亞盃男子足球賽在射門次數、射門時間、射門區域、不同部位射門得分及不同司職位置射門得分等之分析。研究對象是以本屆東亞盃男子足球錦標賽的4個參賽國家為主。研究方法以V8攝錄影機現場拍攝全場比賽之並經慢動作放映、記錄，再進行分析比較擷取本研究所需個各項數據，所得的資料以描述性統計與χ2統計方法考驗 (Chi-Square test) 來檢定各項差異情形。經由分析結果顯示:一、在本屆射門次數未達顯著差異外，其他以射門時間、區域、不同部位、不同司職位置等射門得分均達顯著差異(*p<.05)。二、射門時間：以上半場31－45分入球最多，而下半場61－90分也是入球之高峰期，同時經卡方檢定，均達顯著差異（χ2值=11.12）。三、在射門區域：為C區域入球數15球，佔41.67％最高；其次是B區域為11球，佔30.55％；依數據顯示射門成功之區域仍以C、B區所佔的比率最高，經卡方檢定均顯著差異（χ2值=49.69）。四、不同部位射門：以右腳射門得分22球最多，佔61.11％，與慣用腳有關，經卡方檢定均出現顯著差異（χ2值=82.09）。五、不同司職位置射門：前鋒入球25球，佔總入球數69.44％，經卡分檢定均達到顯著差異（χ2值=124.05）顯示前鋒仍是扮演主要得分的角色。然而在本屆射門次數未達顯著差異而言，顯示本屆射門技術的準確性與把握性是有重大突破。

The aim of the present study is to analyze the frequency, time and areas of shooting and the shooting leg and position to score a goal. The subjects of this study were the four teams competing in the 2010 East Asian Men Football Championship. The data were collected during the competition using V8 camera. The film was then played in slow motion in order to record all the information needed for further analysis. Descriptive statistics and Chi-Square test were used to examine the effects of the various shooting techniques of interest. The results suggest ed that: Firstly, except for the shooting frequency, there are significant differences among the various shooting time, areas, and positions and between the two shooting legs (*p<.05). Secondly, for the shooting time, more goals are scored during the 31st to 45th minute in the first half and during the 61st to 90th minute in the second half　(Chi-Square test, χ2=11.12). Thirdly, as far as the shooting areas are concerned, the highest percentage of point is scored in area C (41.67%, 15 goals) and it is followed by the area B (30.55%, 11 goals). Therefore, the findings show that the area C and B are the two most likely areas for successful goal with statistically significant difference. (Chi-Square test, χ2=49.69). Fourthly, shooting by the right leg scored more than by the left leg (61.11%, 22 goals) (Chi-Square test, χ2=82.09), which might result from the advantage of dominant leg. Fifthly, 25 goals by forward as 61.11％ of all scored the most among all positions (Chi-Square test, χ2=124.05), which implies that the forward plays an important role for winning. In addition, the null results of shooting frequency indicated that there is a major breakthrough for the accuracy and certainty of shooting in this year.
