雙自由球員與單自由球員在接發球與防守效果之比較

Abstract

前言：自1999年得球得分制的改變以及增訂了特殊身分的自由球員後，比賽的得分結構也成了強力發球的趨勢，企圖在第一波進攻上搶分抑或是破壞對手組織進攻，自由球員成了提高接發球到位率以及防守起球率的角色。有鑑於各國攻擊手威力不斷增強以及在技戰術上的提升，單一自由球員在接發球及防守上如欲趨於全面，可想而知其訓練量的加重，以及在球場上體力消耗也是一個問題，因此，國際排球總會(FIVB)透過不斷的測試與修改，在2012倫敦奧運時便開始使用了「雙自由」的新規則。目的：在2013年天津東亞運拿下金牌的中華男排，即選擇使用不同以往的雙自由規則，因此本研究的目的旨在了解並探討中華男排雙自由球員與其對戰對手單自由球員在接發球與防守之效果分析比較。方法：以2013年天津東亞運男子中華台北隊及其對戰對手(香港、中國、南韓、日本)之比賽內容進行運動表現記錄，記錄中華隊雙自由球員及對戰對手單自由球員在接發球與防守之效果，並使用獨立樣本 t 考驗進行分析。結果：雙自由球員與單自由球員在接發球表現上沒有顯著差異；雙自由球員與單自由球員在防守表現上有達顯著差異(p<.05)。建議可多把握防守後反攻得分的機會，並提升接發球好球率，未來可在其他賽事多嘗試使用雙自由規則。Background: Since 1999, the scoring rules has changed and the number of libero player in one play has increased.. Given that attackers around the world now perform more powerful attacks than before, a libero has to be more comprehensive when handling reception or defense in a game. In addition, physical exertion for single libero in a game has become a challenge for players. Purpose of the study: In 2013 the 6th East Asian Game in Tianjin. Chinese Taipei Men’s volleyball team chose to use double libero. This study focuses on comparing the effect of reception and defense between using double libero and single libero through the case of Chinese Taipei men’s volleyball team. Method: Using the independent sample T test to analyze the records of game between Chinese Taipei men’s volleyball team and its opponents (Hong Kong, China, South Korea, and Japan) in 2013 East Asian Game in Tianjin. The analysis focuses on comparing the effect of the reception and defense between Chinese Taipei men’s volleyball team using double libero and their opponents using single libero. Results: There is no significant difference in the performance of reception between using double libero and single libero; however, significant differences in the performance of defense (p<.05) were found in the comparison between using double libero and single libero. This study suggests that players grasp the opportunity of defensive counterattack to score, increase the success rate when receiving a serve, and try to use double libero more in the future.
