<p>目的：本研究旨在探索高強度排球比賽中技術指標之排名與獲勝基準。方法：資料透過排球資訊系統 (Volleyball Information System, VIS) 收集2017-2021 年台灣企業排球聯賽攻守數據。採用迴歸分析及條件機率鑑定各項技術指標之排名及獲勝基準。結果：結果顯示各項指標之排名及獲勝基準僅有些微地性別差異。首先，防守失誤及攻擊得分是男子組前兩名的指標，女子組則是攻擊得分為最重要之指標，防守失誤次之。其餘的八個指標排名男女組皆一致。 其次，若要將獲勝機率提升至50%以上 (獲勝基準)，攻擊得分必須要超過每局一半的分數，但僅僅2到3個攔網得分便能達到獲勝基準。再者，少數的發球失誤並不嚴重拉低獲勝機率，但1到2顆的發球得分卻可以達到獲勝基準。雖然非得分的技術指標 (如接發球失誤及舉球失誤) 之數量不多，但卻顯得相當重要。結論：條件機率足以呈現排球各項技術指標中整體團隊之獲勝基準。本研究基於統計的佐證提出陣容組建、訓練計畫、以及戰術運用等實務建議。</p> <p> </p><p>Purpose: This study aimed to investigate the rankings and benchmarks of performance indicators in high- intensity volleyball games. Methods: Data were collected through the Volleyball Information System (VIS)for the Top Volleyball League (TVL) seasons in Taiwan from 2017 to 2021. We adopted regression analysis and conditional probability to identify rankings and benchmarks of performance indicators. Results: Results revealed that there were no major differences between the sexes. Dig fault and spike point ranked men’s top 2 indicators while spike point possessed women’s highest rank followed by dig fault. The rankings for the remaining eight indicators were consistent across both sexes. In order to reach over 50% of the winning probability for a set (benchmark), more than half of the points must come from spiking. Achieving the benchmark could be accomplished with just 2 to 3 blocks, and a few service faults were not detrimental. In addition, 1 to 3 service aces was essential to meet the benchmark. Non-scoring indicators such as reception fault and set fault were not common but crucial for overall performance. Conclusion: Conditional probability could sufficiently present benchmarks of overall volleyball team performance indicators. This study offers statistical evidence for roster construction, training plans, and tactic applications.</p> <p> </p>
