To compare whole-body vibration (WBV) with traditional recovery protocols after a high-intensity training bout.
In a randomized crossover study, 16 athletes performed 6 × 30-s Wingate sprints before completing either an active recovery (10 min of cycling and stretching) or WBV for 10 min in a series of exercises on a vibration platform. Muscle hemodynamics (assessed via near-infrared spectroscopy) were measured before and during exercise and into the 10-min recovery period. Blood lactate concentration, vertical jump, quadriceps strength, flexibility, rating of perceived exertion (RPE), muscle soreness, and performance during a single 30-s Wingate test were assessed at baseline and 30 and 60 min postexercise. A subset of participants (n = 6) completed a 3rd identical trial (1 wk later) using a passive 10-min recovery period (sitting).
There were no clear effects between the recovery protocols for blood lactate concentration, quadriceps strength, jump height, flexibility, RPE, muscle soreness, or single Wingate performance across all measured recovery time points. However, the WBV recovery protocol substantially increased the tissue-oxygenation index compared with the active (11.2% ± 2.4% [mean ± 95% CI], effect size [ES] = 3.1, and -7.3% ± 4.1%, ES = -2.1 for the 10 min postexercise and postrecovery, respectively) and passive recovery conditions (4.1% ± 2.2%, ES = 1.3, 10 min postexercise only).
Although WBV during recovery increased muscle oxygenation, it had little effect in improving subsequent performance compared with a normal active recovery.
比较高强度训练后全身振动(WBV)与传统恢复方案的效果。
在一项随机交叉研究中,16名运动员在完成6组30秒的温盖特冲刺跑后,分别进行主动恢复(10分钟的骑行和拉伸)或在振动平台上进行一系列练习,进行10分钟的全身振动。在运动前、运动期间以及10分钟的恢复期内测量肌肉血液动力学(通过近红外光谱法评估)。在基线以及运动后30分钟和60分钟时评估血乳酸浓度、垂直跳跃、股四头肌力量、柔韧性、主观用力程度(RPE)、肌肉酸痛程度以及单次30秒温盖特测试中的表现。一部分参与者(n = 6)在1周后进行了第三次相同试验,采用10分钟的被动恢复期(坐着)。
在所有测量的恢复时间点,恢复方案在血乳酸浓度、股四头肌力量、跳跃高度、柔韧性、RPE、肌肉酸痛程度或单次温盖特测试表现方面没有明显差异。然而,与主动恢复(运动后10分钟和恢复后10分钟分别为11.2%±2.4%[平均值±95%CI],效应大小[ES]=3.1,以及-7.3%±4.1%,ES=-2.1)和被动恢复条件(仅运动后10分钟为4.1%±2.2%,ES = 1.3)相比,全身振动恢复方案显著提高了组织氧合指数。
虽然恢复期间的全身振动增加了肌肉氧合,但与正常的主动恢复相比,对改善后续表现的作用不大。
