频率和振幅决定了全身振动（WBV）运动的训练负荷，从而决定了可能的神经肌肉适应。我们研究了单次WBV的幅度和频率对柔韧性和蹲跳性能（SJ）的影响以及这些影响的时间过程。在振幅研究中，25只雌性动物以25 Hz的频率和4 mm、6 mm和8 mm的振幅进行了6 min的三种振动方案（VP）和一种对照方案（CP）。在频率研究中，18只雌性动物在6 mm振幅和15 Hz、20 Hz和30 Hz频率下进行了3次VP和1次CP。在恢复前、恢复后即刻和恢复后15 min测量柔韧性和SJ。所有方案均在侧对侧交替振动板上进行。在振幅研究中，（p <0.01）VP4、VP6、VP8即刻后（分别为31.8 +/-8.2、31.9 +/-7.6、31.5 +/-7.9）和15 min恢复期（分别为31.6 ± 8.1、31.5 ± 7.9、31.0 ± 8.2）与振动前（分别为30.2 +/-8.6、30.3 +/-8.1、30.2 +/-8.3），但CP中保持不变（振动后即刻为30.6 +/-8.3，振动后15分钟为30.7 +/-8.2，振动前为30.4 +/-8.2）。在频率研究中，提高了灵活性（p <0.01）在VP 15、VP 20、VP 30中即刻后（分别为31.5 +/-5.2、31.3 +/-5、31.7 +/-5.3）和15 min恢复期（分别为31.3 ± 5.4、31.3 ± 5.0、31.3 ± 5.3）与振动前（分别为30.6 +/-5.4、30.2 +/-5.7、30.3 +/-5.9），但在CP中没有（30.7 +/-5.1，15分钟时30.6 +/-5，振动前30.5 +/-5.7）。振幅和频率对SJ无显著影响。总之，使用左右交替振动板的单次WBV回合可以增加持续至少15分钟的灵活性，而不会改变跳跃性能。观察到这些效应与频率和振幅无关。(C)2009年澳大利亚运动医学。由爱思唯尔有限公司出版。保留所有权利。
Frequency and amplitude determine the training load of whole-body vibration (WBV) exercise and thereby possible neuromuscular adaptations. We investigated the effects of amplitude and frequency of a single bout of WBV on flexibility and squat jump performance (SJ) and the time-course of these effects. In the amplitude study, twenty-five females performed three vibration protocols (VPs) for 6 min at frequency of 25 Hz and amplitudes of 4 mm, 6 mm, and 8 mm and one control protocol (CP). In the frequency study, eighteen females performed three VPs at 6 mm amplitude and frequencies of 15 Hz, 20 Hz, and 30Hz and one CP. Flexibility and SJ were measured before, immediately-post and 15 min recovery. All protocols were performed on a side-to-side alternating vibration plate. In the amplitude study, flexibility was improved (p < 0.01) immediately-post in VP4, VP6, VP8 (31.8 +/- 8.2, 31.9 +/- 7.6, 31.5 +/- 7.9, respectively) and at 15 min recovery (31.6 +/- 8.1, 31.5 +/- 7.9, 31.0 +/- 8.2, respectively) vs. pre-vibration (30.2 +/- 8.6, 30.3 +/- 8.1, 30.2 +/- 8.3, respectively), but remained unchanged in CP (30.6 +/- 8.3 immediately-post, 30.7 +/- 8.2 at 15 min vs. 30.4 +/- 8.2 pre-vibration). In the frequency study, flexibility was improved (p < 0.01) immediately-post in VP15, VP20, VP30 (31.5 +/- 5.2, 31.3 +/- 5, 31.7 +/- 5.3, respectively) and at 15 min recovery (31.3 +/- 5.4, 31.3 +/- 5.0, 31.3 +/- 5.3, respectively) vs. pre-vibration (30.6 +/- 5.4, 30.2 +/- 5.7, 30.3 +/- 5.9, respectively), but not in CP (30.7 +/- 5.1 immediately-post, 30.6 +/- 5 at 15 min vs. pre-vibration 30.5 +/- 5.7). There were no significant effects of amplitude or frequency on SJ. In conclusion, a single WBV bout using a side-to-side alternating vibration plate may increase flexibility which persists for at least 15 min, without altering jumping performance. These effects were observed irrespective of frequency and amplitude. (C) 2009 Sports Medicine Australia. Published by Elsevier Ltd. All rights reserved.
