摘要

本研究旨在以籃球攻守紀錄探討球隊勝負之關鍵及特性，以參加九十九學年度大專籃球聯賽公開男生組第一級之台灣藝術大學男籃隊及其對戰球隊為研究對象，分組預賽共七場次之攻守記錄數據為研究範圍，探討台藝大男籃隊及其對戰球隊之攻守技術表現的情形及勝負場次之攻守技術表現的差異，並透過主成分分析探討台藝大男籃隊整體之特色。研究顯示，平均而言攻守表現上，對戰雙方在攻守數據上的差異並不顯著，而在台藝大的落敗比賽中，兩分命中率、三分球命中率、得分、防守籃板等項目都低於對手，並透過主成分分析，解析出四個主成分：第一個主成分包含三分球得分、三分球命中率及搶截；第二個主成分分別為二分球得分、二分球命中率、得分、進攻籃板（負相關）及助攻；第三個主成分包含罰球命中率（負相關）、阻攻（負相關）、犯規及失誤；罰球得分及防守籃板組成了第四個主成分，此一分析可作為球隊之攻守內容判斷依據。最後，依據本研究結果建議球隊應針對本身之弱點加強訓練，有助於在未來比賽中能夠在戰力上有所提昇。

The purpose of this study was to investigate the key factor of win/lose from offensive and defensive data of basketball games. The case study of National Taiwan University of Arts (NTUA) men's basketball team and its competitors during 99 academia year. This study discussed the difference of offensive and defensive data between NTUA teams and its competitors. Furthermore, Principal Component Analysis (PCA) was used to investigate the characteristics of NTUA team. The results showed that the offensive and defensive performances were not statistically significant between NTUA teams and its competitors. As for the games that NTUA team lost, the 2-point shooting percentage, 3-point shooting percentage, total score, and defense rebound were behind his rivals. PCA indicated four components of NTUA team from offensive and defensive data; the first component include 3-point score, 3-point shooting percentage and steals; the second component include 2-point score, 2-point shooting percentage, total score, offensive rebounds, and assists; the third component include free-throw percentage (negative correlation), block (negative correlation), fouls, and turnover; the fourth component include free-throw score and defensive rebounds. These data can be a useful analysis to judge the team's characteristics. In conclusion, this study suggested that team should step up training for its own weaknesses and this would be helpful for the coming games.
