Abstract:	背景：近年來，非傳統替代式訓練器械逐漸受到關注；而雪橇則是最常被應用的器材之一。目前利用雪橇所進行的研究大多以輕負荷進行訓練，至於探討大重量及高負荷雪橇推行訓練的活化後增益作用相關研究仍缺乏大量科學佐證。目的：本研究旨在探討不同休息時間的高負荷雪橇推行對橄欖球選手運動表現增益之立即影響。方法：招募9名18至22歲大學公開組橄欖球選手為受試者。所有受試者分別以80%自身肌肉量與背蹲舉最大肌力和之總負荷強度，搭配組間休息時間5分鐘與7分鐘，進行3趟10公尺雪橇推行，；測驗項目為3次下蹲跳。統計方法採混合設計二因子變異數分析，考驗其是否達顯著差異性，並以α=0.05為顯著性考驗水準。結果：5分鐘組在峰值功率上達顯著性下降 (F=4.785；p=0.09) ，其餘皆未達顯著性差異 (p>.05) ；而7分鐘組之垂直運動表現 (垂直跳高度、平均力量、平均功率、平均速度、峰值力量、峰值功率與峰值速度) 皆無任何顯著性差異 (p>.05) 。兩者之交互作用也皆未達顯著性差異 (p>.05) 。結論：本研究顯示5分鐘與7分鐘休息時間的雪橇推行運動無法誘發活化後增益作用。建議未來相關研究定義出更適合誘發活化後增益作用的負荷與休息比例。 Background: In recent years, non-traditional alternative training equipment have warranted more attention. Notably, the sled is one of the most commonly used tools. Most of the current researches related to sled exercises were forced on light loading. However, the scientific researches on the post-activation potentiation (PAP) responses after heavy loading or high intensity in sled-pushing exercises have been still limited. Purpose: This study aimed to explore the acute effects of different interset rest duration of sled-pushing exercise on the post-activation potentiation response. Method: 9 male collegiate rugby athletes (20.78 ± 0.83 years old) with two-year experiences of strength training were recruited. The subjects performed three sets of 10-meter sled-pushing with 80% system weight (the summation of the weight of muscle mass + the weight of 1 repetition maximum of back squat), and the inter-set rest were 5 and 7 minutes respectively. The participants performed (countermovement jump, CMJ) test for 3 times before the experiment and after every rest time. The two-way ANOVA mixed design was used to analyze the data of CMJ. The significant level was set at α=0.05. Result: The data revealed that the peak power in 5-mintute inter-rest significantly decreased (F=4.785; p=0.09); but 7-minute inter-rest had non-significant difference (p>.05). The interaction between two groups have non-significant differences (p>.05). Conclusion: This study elucidated that two different inter-set rest (5 and 7 minutes) may not induce the post-activation potentiation response after sled-pushing. It recommended that the future researches could define the optimal radio of loading and inter-rest.
