摘要

本研究旨在探討不同技能水準排球選手在四號位置的扣球時宜，研究對象為國立花蓮教育大學排球校隊四號位置主攻擊手、非主攻擊手、系排球隊、無經驗組之男生各四組，每組各5名，共20名受試者參與測試。研究工具為Panasonic NV-GS 250高速攝影機(60Hz)所拍攝之影片，配合Kwon 3D（3.0版）軟體分析影片。並以單因子變異數分析進行統計考驗，研究結果發現：一、知覺扣球時間上之tau(τ)值在各組之間並無顯著差異。二、不同技術水率動作之穩定性，各組在起跳時間、起跳球高、擊球點、起跳距離等項目上有顯著差異，呈現：（一）非主攻手的起跳時間最早，顯示慣打快速球者，不因位置不同而有所改變。（二）有經驗的選手起跳時球的高度較無經驗者高，故運動技能較好的選手能有較多的時間應用視覺調整攻擊策略。（三）從擊球點分析顯示：主攻擊手在運動控制上的表現均優於其他組別。（四）主攻擊手與無經驗組起跳至擊球距離短於非主攻手。

This study investigated the spike timing of the volleyball players with different skill levels at the fourth position. Twenty males from National Hualien University of Education were evenly designated to four groups according to skill levels: primary hitters of the university team, non-primary hitters of the university team, hitters of the departmental team, and inexperienced hitters. A camera (60Hz) was used to record the actions of Volleyball spiking. The kinematical parameters were analyzed by using the Kwon 3D system. One-way ANOVA was used to test the ‘variables. The statistical significant level was set at α= .05. The main findings of this study were: First, there were no significant differences among groups in the perception of timing of spiking described by tau(τ). Second, there were significant differences in the timing of the initial jump, the height of the ball in the initial jump, the height of the hit point, and the distance of the initial jump to the hitting point as follow. First, the non- primary hitters had the fastest timing of the initial jump in both gender groups, indicating that they might be used to perform the quick attack and did not change their pattern at different positions. Second, the experienced hitters had a higher height of the initial jump compared with the inexperienced hitters in both gender groups, suggesting that the skilled hitters might have more time to adjust their hitting tactics visually. Third, from the analysis of the hitting height, the primary hitters performed a better control of the spiking approach compared to the other groups. Fourth, the primary hitters and the inexperienced hitters had a shorter distance of the initial jump to the hitting point compared with the non-primary hitters.
