2017世界大冠軍杯男子排球賽二波結構性攻擊效益分析

Abstract

前言:排球比賽中的攻擊戰術是主要的得分方式。有別於一波攻擊時防守球員是面對離網較遠的發球攻擊，二波攻擊是在防守近網的各種進攻戰術下開始組織反擊，因此一波攻擊的組織結構遠較二波攻擊多變化。目的:探討2017年世界大冠軍杯排球賽男子組，在不同防守球質、反擊戰術及得分效益間之關聯。方法:以2017世界大冠軍杯男子排球賽15場比賽為研究範圍，以官方網站授權之比賽影片為資料來源，使用Simi Scout標記軟體設計紀錄系統，標記比賽防守表現、反擊戰術及反擊效果等內容，以 SPSS 23.0進行卡方獨立性考驗，檢驗一波攻擊、二波攻擊、攻擊戰術、防守球質及得分效益等比賽表現間之關聯性。結果:一、二波與得分效益，防守球質與攻擊戰術，無攔網下之防守前的攻擊戰術與防守球質，攻擊戰術與得分效益間均達顯著關聯。討論:一波的防守球質優於二波，進而影響攻擊戰術組成的不同，一波相較於二波有較多的快攻及後排攻擊，二波則有相對較多的機會球與無組織的戰術。在有攔網下確實能有效降低攻擊的威力，進而減低防守負擔，在無攔網下較無法產生高分的防守。整體而言，無論一、二波，快攻和6號位後排攻擊戰術有最佳的得分效益。

Introduction: Attack tactics in volleyball matches are the main scoring method. Different from complex I counterattack where the defending player is facing a far-off attack of the service, complex II counterattack is to organize an attack under various offensive tactics near the net. Therefore, there are more tactics can be used in the complex I. Purpose: To explore the relationship between different defensive qualities, counterattack tactics and scoring benefits in the 2017 Men's Volleyball World Grand Champions Cup. Method: The videos of the 15 games of 2017 Men's Volleyball World Grand Champions Cup authorized by the official website were used for data analyses. Simi Scout software was used to record all the variables. The SPSS 23.0 was used to perform the Chi-Squared tests of independence for the scoring performance of complex I, complex II, type of attack tactics, and defensive qualities. Results: There were significant positive associations between the scoring effectiveness and Complex I and II attacks, between defensive quality and types of attack tactics, between the types of attack tactics and the subsequent defense quality under no-blocking condition, as well as between the types of attack tactics and the scoring effects. Discussion: the defensive quality of Complex I was superior to that of complex II, which in turn affects the composition of the attack tactics. In complex I, there were more quick-set attacks and back row attacks. As for complex II, there were more chance balls or unorganized attacks. Blocking could effectively reduce the power of the attack, thereby reducing the defensive burden, and it was less likely to produce high quality defense under the no-block condition. Overall, the quick-set attacks and the back row position 6 attacks were the most effective tactics regardless of types of counterattacks.
