摘要

目的：本研究探討拉力帶組、槓鈴組等長收縮型式的活化後增能作用，在不同恢復時間（4分鐘、8分鐘）對跳躍能力的影響。方法：3名大專盃甲一級籃球員參與重複量數隨機分配之實驗，以Kistler測力板收集下蹲跳，並分析跳躍高度、最大力量峰值、發力率、最大功率等參數。以Wilcoxon符號等級檢定時間及組別的差異，顯著水準值為α=.05。結果：檢定後發現時間和組別在跳躍高度、最大力量峰值、發力率、最大功率沒有顯著差異。結論：以拉力帶及槓鈴組從事3組3秒最大自主等長收縮恢復時間4分鐘及分8鐘無法增進跳躍能力，需再做進一步的探討。

Purpose: This study investigated the effects of the ability of countermovement jump after different isometric contraction post-activation potentiation by using lifting straps or barbell at different recovery times (4 minutes, 8 minutes). Methods: Three college basketball players were recruited. A Kistler force platform was used to evaluate the jumping performance and the BioWare was used to analyze the jump height, peak force, rate of force development and peak power. Wilcoxon sign rank test (Time X Group) was used for statistics and the significant level was set to α = .05. Result: After the intervention, there was no significant difference in time and group between jump height, peak force, rate of force development and peak power. Conclusion: The intervention (3-sets of 3-second maximum isometric contraction and the recovery time of 4 minutes and 8 minutes) cannot improve the jumping ability.
