大專女子排球不同攻擊位置之攻擊效益

Abstract

緒論：排球運動中攻擊是影響比賽勝負相關性最高的動作，本研究以大專女子排球為研究對象，歸納文獻所提出的攻擊效益分級與方法，探討大專女子排球不同攻擊位置之攻擊效益。方法：以112 年大專排球聯賽公開女子組第一級決賽之隊伍之決賽的比賽數據（共計6 場，22 局，906 分，1582 次攻擊動作）進行不同攻擊位置的攻擊效益分析，以出現次數、百分比及攻擊效益係數等描述性統計和卡方 (Chi- Square) 百分比適合度檢定分析5 項攻擊效益（攻擊得分、對方無攻擊回球、受限攻擊效果、無攻擊效果、攻擊失分）分別在不同攻擊手位置與不同排名隊伍之間的差異，卡方檢定顯著性水平定為p< 0.05。結果：1.不同位置的攻擊手所表現出來的整體攻擊效益的比例 是相似的(2  = 1.48, df=8, p =0.99 > 0.05, φ =0.03)，2. 從不同排名隊伍的所有位置攻擊 效益達顯著差異(2  = 39.99, df=20, p < 0.05, φ =0.15)以及各隊伍之間對不同位置攻擊手 的使用達顯著差異(2  = 128.67, df=10, p <0 .05, φ =0.29)， 3. 不同攻擊位置在排名領先 攻擊手的攻擊效益皆未達顯著差異。結論：這5 項攻擊效益的分級是評估攻擊手貢獻 度的有效評量方法，球隊倚重的主攻與副攻位置有所不同，但快攻在一個球隊中貢獻 度很高的位置。從攻擊效益的角度來看大會所公布的最佳選手評定的結果也些微落 差。建議未來對不同層級賽事將攻擊效益做進一步分析，適當地納入攻擊效益係數做 為攻擊表現的評量參考指標。 關鍵詞：運動表現分析、攻擊、效益、不同位置Introduction:. The attack is the action that has the highest correlation with the success ofvolleyball team. The purpose of this study was to find out the common tendencies of efficacyof attack between attack-positions among different ranking teams. Methods: The sample was1582 attack actions played by 6 1st-level of collegiate female volleyball matches, 22 sets, 906points, which released by Chinese Taipei University Sports Federation website was collectedand analysed. A descriptive analysis (occurrence, occurrence percentage and coefficient of attack efficacy), and an inferential analysis were made. Chi-square goodness of fit test was used to examine the difference of distribution of percentages among the efficacy variables between different positions and different ranking teams. The level of significance was established at p< 0.05. Results: 1. The proportion of the overall attack efficacy shown by the attackers in different positions is similar ( = 1.48, df = 8, p = 0.99> .05, φ = 0.03), 2. There were significant differences in attack efficacy from all positions of the ranked teams ( = 39.99, df=20, p < .05, φ =0.15) and between teams ( = 128.67, df=10, p < .05, φ =0.29), 3. There is no significant difference in the attack efficacy of the leading attackers at different attack positions. Conclusions: These 5 levels of attack efficacy are a valid measure of the attacker's contribution, and teams rely on different positions in side-attacker and opposite-attacker,but the middle- block attacker has a high contribution in a team. From the point of view of the effectiveness of the attack, the results of the evaluation of the best attackers of each positions announced by official report is controversial. It is suggested that in the future, efficacy of the attack in competition of different levels should be further studied, and then the evaluation method of efficacy of attack should be appropriately applied in the evaluation of attack performance.
