前言：助跑單腳垂直跳是一種常出現於各種運動場上的動作，但是對於執行該動作訓練的優 勢或動作分析上尚未有太多研究專注於此。研究目的：探討不同助跑速度與不同助跑距離單 腳垂直跳動作的運動學、動力學與肌電圖差異，希望能找出適當的助跑單腳垂直跳助跑速度 與助跑距離組合。研究方法：招募15名自願參與本研究的曱組男性排球運動員，以隨機抽籤 方式安排助跑速度與距離進行助跑單腳垂直跳測試，每個助跑單腳垂直跳組合進行3次跳， 取3次平均進行分析。利用11台Motion紅外線高速攝影機（200Hz)，1塊AMTI測力板 (2000Hz)與Delsys無線表面肌電圖（2000Hz)，通過Motion Analysis同步擷取資料。本研究 統計分析以2x3 two-way ANOVA(助跑速度x助跑距離）考驗受試者各項參數的差異性。統 計顯著水準皆定為a=.05，當達到顯著水準時，利用Bonferroni法進行事後比較（Bonferroni post hoc)。 Introduction: the running 1-legged vertical jump is often seen in sports competition, but seldom study focuses on benefit of its training and motion analysis. Purpose: the present study compares the differences of kinematic, kinetic and EMG between different approaching speed and distance on running 1-legged vertical jump. Method: fifteen elite male college volleyball players participated in this study voluntarily. Participants perform running 1-legged vertical jump with different combination of approaching speed and distance randomly. Every combination is performed for 3 times. All data are recorded using synchronized high speed camera (Motion Analysis Corporation, Santa Rosa, CA, USA ), force plate (AMTI Inc., Watertown, MA, USA) and surface EMG (Delsys Inc., Boston, MA, USA.). Two-way ANOVAs (2 approaching speed x 3 approaching distance), complemented with Bonferroni post hoc, are used for establishing differences between approaching conditions. Significance level is set at a= .05.
