不同頻率全身震動對下肢運動表現之立即性影響

The Immediate Effect of Whole Body Vibration with Different

目的：探討兩種不同頻率(肌梭激發頻率與下肢肌肉共振頻率)的全身性震動對於下肢運動表現之立即性影響。方法：本研究以13位健康大學生為受試者，並依照平衡次序法依序進行三種不同訓練(高頻刺激：頻率32Hz、振幅1mm。低頻震動介入：頻率18Hz、振幅3mm。控制組：無震動刺激)，分別在震動平台上做60秒，2秒1次的蹲踞訓練，每次訓練五組。刺激前後以測力板擷取連續三次垂直跳與單足閉眼站立平衡。結果：連續三次垂直跳第三跳中，低頻震動介入在後測的跳躍高度及衝量顯著高於前測(p.05)。結論：低頻之震動刺激對於連續三次垂直跳之第三跳跳躍高度及衝量有顯著增進，但無法改善平衡能力。

Purpose: Investigate the immediate effect of two different frequencies (muscle spindle stimulus frequency and lower-limb muscle resonance frequency) of whole body vibration on the performance of lower limbs. Methods: Thirteen healthy university students were recruited in this study. All of the subjects received 3 different intervention， which were high frequency vibration stimulation (HFV， frequency/amplitude: 32 Hz/1mm)， low frequency vibration stimulation (LFV， frequency/amplitude: 18 Hz/3mm) and control (CON， no vibration stimulation) while they were doing squat training for 60 seconds in the frequency of 2 seconds per squat. Three consecutive counter movement jumps (CMJ3) and standing balance test (BT) with eyes closed were performed in the pre and post test of this study. Results: The height of counter movement jump in the third jump and impulse increased significantly between pre and post test after the stimulation (p
