| Summary: | 碩士 === 中國文化大學 === 體育學系運動教練碩博士班 === 107 === 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.
