跆拳道踢擊期間的注意需求

中文摘要

本研究的主要目的係以雙重任務設計探討跆拳道旋踢踢擊過程的各階段注意需求，實驗以23名跆拳道運動員為實驗參與者，其平均年齡16.4 ± 0.8歲、平均身高169.7 ± 5.8 cm、平均體重61.1 ± 12.2 kg，每位實驗參與者均需執行40次旋踢的主要任務，而實驗則在旋踢的準備階段（踢擊腳離地前）、踢擊階段、踢中目標階段與踢擊腳收腳階段隨機加入簡單反應時間測試。實驗參與者的踢擊力量、反應時間按鍵訊號則分別使用大道跆拳道專用電子護具及計分系統、BioPac MP-150和50 G加速度傳感器進行紀錄。經重複量數單因子變異數分析後，結果發現在踢擊階段執行反應時間測試時的踢擊力量顯著小於單純踢擊動作，反應時間測試結果顯示由快至慢依序為簡單反應時間、收腳階段、踢擊階段與準備階段。此結果說明了執行旋踢動作時，跆拳道運動員在準備階段與踢擊階段期間的注意需求相當高。

The Attentional Demand during the Taekwondo Kick

Abstract

The purpose of this study was to investigate the attentional demand during the roundhouse kick process of Taekwondo by the dual-task design. Twenty-three Taekwondo athletes were recruited to participate in this study. Their average age, height, and body weight were 16.4 ± 0.8 years old, 169.7 ± 5.8 cm, and 61.1 ± 12.2 kg, respectively. Each participant was asked to perform 40 roundhouse kick trials as the primary task, but the simple reaction time test (RT) would be inserted at four probe position randomly that prepare phase (before kick leg takeoff), kicking phase, impact phase, and backward phase of roundhouse kick. Dae do protector scoring system and BioPac MP-150 with 50 G accelerometer (2000 Hz) were used to record the kick force and switch pulse respectively. Repeated measures one way ANOVA showed the kick force with RT at kicking phase was significantly less than simple kick movement. The RT results from fast to slow in sequence were simple RT, at backward phase, at kick phase, and at prepare phase. It indicated that the prepare phase and kick phase were the important duration that a Taekwondo athlete required higher attentional demands to execute the roundhouse kick.
