摘要

本研究主要在探討四週全身震動刺激訓練對於下肢爆發力及跆拳道專項踢擊表現的影響。本研究以28名大專跆拳道專項選手為對象，先依量級分類，再隨機分為實驗組14名（7男7女）、控制組14名（9男5女）。實驗組與控制組除了接受四週且每周四次的常規式跆拳道專項訓練外，所有參與者均接受四種不同半蹲動作，每種30秒，共計2分鐘3回合，組間休息60秒。控制組站在訓練場旁的地面無震動刺激，但震動組站在震動平台上，震動刺激為30-50Hz，震幅6mm。四週訓練前、後進行垂直跳高度、發力率和衝量檢測，及旋踢與後踢的反應時間、動作時間表現。以前測表現為共變數，進行單因子共變數分析（one-way ANCOVA）考驗實驗組和控制組在四週震動訓練後各參數表現的差異，所有顯著水準皆定為α=.05。調整後平均數結果發現：實驗組在接受震動刺激訓練後的跳躍高度、發力率顯著高於對照組，但是兩組間的兩種踢擊反應時間與動作時間並無顯著差異。經過四週震動刺激訓練有助於提升大專跆拳道專項選手的下肢爆發力，但對卻無法加速踢擊動作表現。

The aim of this study was to evaluate the effect of 4-week whole body vibration training on explosive power and kicking performance of taekwondo (TKD) athletes. Twenty-eight college TKD athletes were recruited to participate in this study. Athletes were classified by their body weight, and then assigned into vibration group (VG, n=14: 7 males & 7 females) or control group (CG, n=14: 9 males & 5 females). All participants were underwent a regular TKD training 4 times per week for 4 weeks. In addition to training, athletes performed four different static squatting movements, 30 seconds each for a total vibration stimulus of 2 minutes for one set, 3 sets with 60-second rest time between the sets after a TKD training program. Athletes in VG squatted on vibration platform with frequencies of 30-50Hz and amplitude at 6 mm, while athletes in CG squatted only on ground. The vertical jump height and rate of force development as well as 2 kicking performance (roundhouse kick & back kick), including reaction time and movement time were examined before and after 4-week training period. One-way analysis of covariance was used to compare the difference in each parameter between VG and CG after the training program with pre-test values as a covariate. The statistical significant level was set at α=.05. The results showed that jump height and rate of force development in VG were significantly higher than CG. However, both kinds of kicking performance, including reaction time and movement time were not significantly different between the groups. Therefore, our study suggests that 4-week vibration training improved only jumping performance, not kicking performance in college TKD athletes.
