目的:活化後增能 (Post-activation potentiation, PAP) 是指主要活動前進行高功率之 肌肉收縮刺激,使肌肉收縮力急劇改善;並可能發生活化後表現增強 (Post-activation performance enhancement, PAPE) 使優化運動表現。然而以重負荷或高收縮速度的方 式進行訓練皆屬高功率之訓練,故何者是促發PAP優勢方式並能有較佳PAPE尚待 研究驗證。本研究的目的是比較跆拳道選手以重負荷半蹲舉 (Half squat, HS) 及高收 縮速度蹲跳 (Squat jump, SJ) 促發PAP及PAPE之差異。方法:以12名曾獲全國賽 前三名之男性青少年跆拳道選手為受試者 (年齡 = 16.2±1.1歲,身高 =173.1±4.1公 分,體重 = 60.3±5.5 公斤) 並隨機分配為二組,每組交替執行HS及SJ之訓練動作 (HS = 6 × 85% 1 RM,SJ = 6 × 30% 1 RM),二種執行方式間隔 48 小時。受試者在 HS 或SJ 執行前及執行後進行各依變項檢測,包括:最大自發性等長收縮之峰值力 量 (Peak force, PF)、踢擊速度 (Kick speed, KS) 與力量 (Kick force, KF)、蹲踞跳高 度 (Heigh of count movement jump, HCMJ)、15 公尺衝刺速度 (Velocity of 15m sprint, V15m) 。以相依樣本t檢定比較HS與SJ促發PAP及PAPE之差異。結果:執行 HS 與SJ後所測得之PF,均顯著高於前測 (p .05)。HS對KF之增強率顯著高於SJ (p
Purpose: Post-activation potentiation (PAP) is a phenomenon which can improve force performance after a high-power output activity. the PAP mechanism could influence post-activation-performance enhancement (PAPE) to increase sporting performance. Heavy load training or high velocity training are both high-power output training method, but which method is better to induce PAP and enhance PAPE remains unclear. This study aimed to analysis the effects of heavy load and high velocity resistance training on PAP and PAPE in young Taekwondo athletes. Methods: twelve young male Taekwondo athletes were divided into two groups. Each group alternated the training method of half squat and squat jump (HS = 6 × 85% 1 RM, SJ = 6 × 30% 1 RM). The interval between HS and SJ training was 48 hours. Peak force of maximum voluntary isometric contraction (PF), kick speed (KS), kick force (KF), counter movement jump height (CMJH), velocity of 15m sprint (V15m) were tested to analyze PAP and PAPE. Data were analyzed by using Paired-Sample T-test to compare differences between HS and SJ. Results: After HS and SJ, PF was significantly higher than the pre-test. (p .05). The enhancement rate of HS on KF was significantly higher than that of SJ (p
