To quantify the acute effect of whole body vibration (WBV) training on arm countermovement vertical jump (ACMVJ), grip strength, and flexibility performance.
Eighteen female elite field hockey players each completed three interventions of WBV, control, and cycling in a balanced random manner. WBV was performed on a Galileo machine (26 Hz) with six different exercises being performed. For the control, the same six exercises were performed at 0 Hz, whilst cycling was performed at 50 W. Each intervention was 5 min in duration with ACMVJ, grip strength, and flexibility measurements being conducted pre and post intervention.
There was a positive interaction effect (intervention x pre-post) of enhanced ACMVJ (p<0.001) and flexibility (p<0.05) parameters following WBV; however no changes were observed after the control and cycling interventions. There was no interaction effect for grip strength following the three interventions.
Acute WBV causes neural potentiation of the stretch reflex loop as shown by the improved ACMVJ and flexibility performance. Additionally, muscle groups less proportionally exposed to vibration do not exhibit physiological changes that potentiate muscular performance.
量化全身振动(WBV)训练对手臂反向运动垂直跳(ACMVJ)、握力和柔韧性表现的急性影响。
18名女子精英曲棍球运动员以平衡随机的方式分别完成了WBV、对照和骑行三种干预。在伽利略机器上进行WBV(26赫兹),并进行六种不同的练习。对于对照,在0赫兹下进行相同的六种练习,而骑行在50瓦功率下进行。每次干预持续5分钟,在干预前后进行ACMVJ、握力和柔韧性测量。
WBV后ACMVJ(p<0.001)和柔韧性(p<0.05)参数有增强的正向交互作用(干预×前后);然而,对照和骑行干预后未观察到变化。三种干预后握力无交互作用。
急性WBV导致牵张反射环的神经增强,如ACMVJ和柔韧性表现的改善所示。此外,较少比例暴露于振动的肌肉群未表现出增强肌肉表现的生理变化。
