射門距離與足球守門員位置之關係

　　本研究對象為參加98年全國運動會男子足球決賽四強隊伍，分別為臺北市、高雄縣、臺南縣、花蓮縣等；試圖以具體距離數據測出射門距離（球與底線）與守門員位置（球與對方守門員）之關係為本研究目的；研究方法是以擷取現場實錄畫面，套入CoreDraw_x3軟體繪成的球場畫面圖，並測出實際距離，再以pearson積差相關進行相關性統計分析。經過分析結果：射門距離與守門員位置之關係為（r=0.98），且（p<.05）顯示兩者之間具有高度正相關。相關變數分析後的結論：射門距離與守門員位置顯示高相關，也就是說射門距離（球與底線）越遠，球與對方守門員的位置就越遠；射門距離（球與底線）越近，球與對方守門員的位置就越近。 　　This research was based on the best 4 teams that are respectively as Taipei City team, Kaohsiung County team, Tainan County team and Hualien County team for the Men’s Football Final of the National Athletic Meets in 2009. Of the purpose of this study, it would base Pearson correlation coefficient to found out the correlation of distance between players (when taking shots and scoring goals) to end line and the distance between opponent’s goalkeeper and the ball. CoreDrawx3 software was used to obtain the actual distance with video scene to carry out this research. As found from analyzed results, the correlations of distance between players (when taking a shot and scoring a goal) to end line and the distance between opponent’s goalkeeper and ball of each team were（r=0.98）(P<.05), and it showed high correlation between the two. As we were to integrate all figures obtained,,following conclusions were found: the distance between players (when taking a shot and scoring a goal) to end line and the distance between opponent’s goalkeeper and ball was highly related. As such, it indicated that the farther(away from end line) the player took a shot, the farther the distance between the ball and opponent’s goalkeeper would be. Besides, the closer (to end line) the player took a shot the closer the distance between the ball and opponent’s goalkeeper would be.
