| 中文摘要 | 緒論:高強度阻力訓練(≥ 85%最大反覆次數[85% of 1 repetition maximum, 85%1RM])可以提升隨後的運動表現,稱之為活化後增能作用(post-activation potentiation , PAP)。速度依循訓練(velocity-based training, VBT)可透過設定訓練時的向心速度流失(velocity loss, VL)比例控制訓練量以及疲勞程度。然而,目前低(5-20%)、高(>20%)VL對於垂直跳的PAP誘發效果仍不清楚。因此,本研究目的為探討低、高VL下肢高強度阻力訓練對後續下蹲跳(countermovement jump, CMJ)表現的急性影響。方法:招募12名有阻力訓練經驗的年輕男性(年齡:21.0 ± 0.8歲;身高:175.1 ± 2.9公分;體重:70.9 ± 6.0公斤),以交叉設計(crossover designs)、平衡次序方法(counterbalancing method)進行3組速度流失20%(VL20)或30%(VL30)、強度90%1RM的半蹲舉(half squat, HS),在HS訓練前以及訓練後第7分鐘進行CMJ測驗。以重複量數二因子變異數(two-way repeated measured ANOVA)進行統計分析。信心水準設定為α = .05。結果:CMJ各項參數經過二因子統計分析,沒有交互作用存在(p > .05)。後續進行主要效果分析,結果顯示在組別因子(p > .05)以及時間因子(p > .05)皆沒有顯著差異。結論:本研究結果指出VL20、VL30進行高強度HS皆無法有效提升訓練後第7分鐘的CMJ表現。因此,教練、運動員以誘發PAP效應為訓練目的時,進行高強度HS應避免設定>20%的速度流失。建議未來研究可以探討其他速度流失閾值(如:5%、10%、15%)的PAP效果,以期望建構出VBT誘發下肢PAP效果的有效處方。 |
| 英文摘要 | Introduction: High-intensity resistance training (≥ 85% of one repetition maximum [85%1RM]) can enhance subsequent exercise performance. This phenomenon has been termed post-activation potentiation (PAP). Velocity-based training (VBT) controls training volume and fatigue by setting the proportion of concentric velocity loss (VL) during training. However, the effects of low (5-20%) and high (> 20%) VL on vertical jump performance are still unknown. Therefore, the present study aimed to examine the acute effects of high-intensity resistance training with a low or high VL percentage on subsequent countermovement jump (CMJ) performance in resistance-trained young males. Methods: Twelve resistance-trained young males (age 21.0 ± 0.8 years; height 175.1 ± 2.9 cm; body mass 70.9 ± 6.0 kg) were recruited. The experiment had a crossover design and followed a counterbalancing method, where each participant performed three sets of half squat (HS) with 90%1RM at a 20% (VL20) or 30% (VL30) decrease in mean concentric velocity. The CMJ was performed before (pretest) and 7 minutes after (post-test) HS. A two-way repeated measures ANOVA (group [VL20 vs. VL30] × time [pre-test vs. post-test]), with the Bonferroni post-hoc test, was performed for each dependent variable. Statistical significance was accepted at the α = .05 level. Results: No significant group × time interactions were observed in the two-way repeated measures ANOVA for any of the CMJ parameters (p > .05). No significant main effects of group or time were observed for CMJ performance (p > .05). Conclusion: This study found that high-intensity HS with low (20%) or high (30%) VL was ineffective in improving CMJ performance. Therefore, when coaches and athletes aim to induce the PAP effect during training, it is important to avoid setting a VL threshold > 20% for high-intensity HS. Future research should explore different VL thresholds (e.g., 5%, 10%, and 15%) to construct an effective VBT training prescription for enhancing CMJ performance. |
