目的：量化的急性效应的全身振动（WBV）训练手臂反向运动垂直跳跃（ACMVJ），握力，和灵活性performance.Methods：18名女子优秀曲棍球运动员完成三个干预WBV，控制，和骑自行车在平衡的随机方式。WBV在Galileo机器（26 Hz）上进行，其中进行六种不同的练习。对于对照组，在0 Hz下进行相同的六次锻炼，而在50 W下进行骑行。每次干预持续时间为5分钟，ACMVJ，握力和灵活性测量正在进行前和后intervention.Results：有一个积极的相互作用效果（干预x前后）增强ACMVJ（p< 0.001）和灵活性（p< 0.05）参数以下WBV，但没有变化后，观察到控制和骑自行车干预。有没有相互作用的影响，握力以下三个interventions.Conclusions：急性WBV导致神经增强的牵张反射环所示的改进ACMVJ和灵活性性能。此外，肌肉群较少比例地暴露于振动不会表现出增强肌肉性能的生理变化。
Objective: To quantify the acute effect of whole body vibration (WBV) training on arm countermovement vertical jump (ACMVJ), grip strength, and flexibility performance.Methods: 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.Results: 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.Conclusions: 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.
