摘要

規則的修改對於球賽的內容勢必會有所變化，2010年國際籃球協會（FIBA）宣布修改籃球規則，將三分線由原本的6.25公尺增至6.75公尺。國內超級籃球聯賽（SBL）於2010年（第八季）開始採用國際籃協所修改的新規則，本研究目的為暸解三分線規則修訂後對籃球攻守表現的影響，以2008-2012年（第六、七、八、九季）SBL7隊每季各105場，共420場例行賽之攻守數據，探討三分線距離修改後對於籃球比賽各項攻守表現之影響。本研究方法由SBL官網所取得的攻守紀錄資料，以隊為單位，將各隊各球季數據所佔百分比進行變異數分析。結果發現三分球距離修改後，三分球投籃次數顯著低於前兩季，同時三分球命中數與三分球命中率亦顯著低於前兩季，造成三分球得分之分數少於前兩季。雖然兩分球投籃次數在第八季明顯增加，但兩分球命中率的下降，兩分球進球數並未明顯增加，使總得分有下滑的趨勢。本研究結論對於SBL各隊開始在第八、九季採用三分線新規則後的例行賽中，三分球與兩分球的出手次數和進球的比例有明顯變化。為了因應新規則的實施，籃球訓練應隨之調整，以維持高水準的籃球攻守表現。

Rules change is bound to affect games played. In 2010, the International Basketball Federation (FIBA) announced the distance increase of the 3-point line position from 6.25 m to 6.75 m in order to keep up with the playing rules of the National Basketball Association (NBA) of the American professional basketball league. The Super Basketball League (SBL) of Taiwan adopted the new 3-point line regulation in season 8 (2010-2011). The purpose of the study was to examine the influence of implementing the new 3-point line regulation to the game performance of the SBL teams. The offensive and defensive statistics of 420 games from seasons 6, 7, 8, and 9 (2008-2012) of 7 teams were analyzed. All the performance statistics were downloaded from the official SBL website, and the ANOVA was used to perform the statistical analyses in percentage of each team over 4 seasons. The results showed that the number of 3-p field goal attempts, the number of 3-p field goals made, and the percentage of the 3-p field goals from the post-rule-change seasons were significantly lower than those from the pre-rule-change seasons, therefore the points scored with 3-p field goals from the post-rule-change seasons were significantly lower than the previous 2 seasons. The number of 2-p field goal attempts was significantly increased in the post-rule-change seasons. However, the significant drop of the 2-p field goal percentage from pre- to post-rule-change seasons did not help to increase the number of 2-p field goals made. As a result, the overall game scores were decreased for the pos t- rule-change seasons. In conclusion, the SBL team performances were influenced by the implementation of the new 3-point line regulation, especially in the number of field goal attempts and field goal percentages from 2-p and 3-p ranges. The training program of the SBL teams should be adjusted to cope with the new regulation in order to maintain a high performance of basketball games.
