慣性阻力訓練機介入熱身對爆發力之立即性影響

Abstract

目的：本研究探討運用慣性阻力訓練機或槓鈴誘發活化增能作用，對於隨後爆發力表現的影響。方法：以16位大專公開組田徑短距離選手為受試者，先進行慢跑與動態伸展之預備熱身，預備熱身結束會進行爆發力前測，前測結束後進行慣性阻力訓練機或槓鈴熱身，控制組則無器材熱身。器材熱身結束後5分鐘進行爆發力後測。所收集的數據以混合設計二因子變異數分析 (mixed-design two-way ANOVA) 比較不同熱身方式對爆發力表現的差異。結果：槓鈴和慣性阻力訓練機熱身後對下蹲跳之高度、力量峰值、平均發力率，以及落地跳之跳躍高度、第二峰值、平均發力率、30公尺衝刺表現皆有顯著提升(p<.05)。結論：運用慣性阻力訓練機或槓鈴熱身，對於5分鐘後的爆發力表現皆有提升作用。

Purpose: This study investigates the effects of using an inertial resistance training machine or a barbell to induce post-activation potentiation on subsequent explosive performance. Methods: Sixteen collegiate-level sprinters were recruited as participants. They initially performed preparatory warm-ups consisting of jogging and dynamic stretching. After completing the preparatory warm-ups, pre-tests for explosive power were conducted. Following the pre-tests, participants performed warm-ups using either an inertial resistance training machine or a barbell, while the control group did not use any equipment for warm-up. Five minutes after completing the equipment warm-up, post-tests for explosive power were conducted. Data collected were analyzed using mixed-design two-way ANOVA to compare the differences in explosive power performance between different warm-up methods. Results: Significant improvements (p<.05) were observed in countermovement jump height, peak power, average rate of force development and drop jump height, second peak power, average rate of force development, and 30-meter sprint performance after warming up with either the barbell or the inertial resistance training machine. Conclusion: Warming up with either the inertial resistance training machine or the barbell enhances explosive power performance five minutes after warm-up.
