摘要

本研究以96學年度高中男子甲組籃球聯賽攻守紀錄為分析要素，採用高中籃球聯賽官方網站所提供之準決賽單循環28場資料，將八強中之某單一隊伍做為分析對象，以該隊7場比賽之單項攻守數據作主成分分析，探討單一高中男子甲組球隊在攻守表現上之特性，藉由主成分分析將原本14項攻守數據簡化成4個主要的趨勢，將有相同趨勢、相關的內容放置在同一主成分的內容中。教練依據專業知識對具有相同趨勢的攻守內容判斷，以找出球隊的特性。結果顯示在第一主成分中包含7項內容，助攻、三分命中率、二分命中率、三分得分等四項，有相同的趨勢；罰球得分、進攻籃板、犯規有相反的趨勢。第二主成分包含防守籃板、二分得分、失誤、總得分等四項。第三主成分內容包含阻攻、抄截。第四主成分為罰球命中率。建議日後教練可透過此方法蒐集相關資料，針對單一球隊進行分析，以瞭解球隊整體特色，作為擬定對戰策略或訓練改進之參考依據。

This study analyzed the offense/defense techniques of men's Level A High School Basketball League (HBL) in the 2007 academic year. Principal Component Analysis (PCA) was used to investigate the characteristics of offense/defense of an individual team. Fourteen items of data about offense/defense were grouped into four principal components. Similar trends and related contents were classified into the same category of PCA. Based on the coach's expertise and judgment, the characteristics of the team were discussed. Results indicated that in the first component, assistance, 3-point shooting percentage, 2-point shooting percentage and the 3-point were positively correlated. Whereas, free throw and offensive rebound foul were negatively correlated with the first four items. The second component was composed of defensive rebound, 2-point, foul and the total score. The third component contained blocked shot and steal. The fourth component was free throw percentage. From this data it is proposed that in future, coaches can adopt this method to analyze the characteristics of an individual team as to be the tactic and training reference.
