Several groups have undertaken studies to evaluate the physiologic effects of whole-body vibration (WBV). However, the value of WBV in a training program remains unknown.
To investigate whether a WBV program results in a better strength and postural control performance than an equivalent exercise program performed without vibration.
Randomized, controlled trial.
Laboratory.
Thirty-three Belgian competitive skiers (ages = 9-15 years).
INTERVENTION(S): Subjects were assigned to either the WBV group or the equivalent resistance (ER) group for 6 weeks of training at 3 times per week.
MAIN OUTCOME MEASURE(S): Isokinetic plantar and dorsiflexion peak torque, isokinetic knee flexion and extension peak torque, explosive strength (high box test), and postural control were assessed before and after the training period.
Both training programs significantly improved isokinetic ankle and knee muscle strength and explosive strength. Moreover, the increases in explosive strength and in plantar-flexor strength at low speed were significantly higher in the WBV group than in the ER group after 6 weeks. However, neither WBV training nor ER training seemed to have an effect on postural control.
A strength training program that includes WBV appears to have additive effects in young skiers compared with an equivalent program that does not include WBV. Therefore, our findings support the hypothesis that WBV training may be a beneficial supplementary training technique in strength programs for young athletes.
多个研究小组已开展研究来评估全身振动（WBV）的生理效应。然而，WBV在训练计划中的价值仍不明确。
探讨与无振动的同等锻炼计划相比，WBV计划是否能带来更好的力量和姿势控制表现。
随机对照试验。
实验室。
33名比利时竞技滑雪运动员（年龄9 - 15岁）。
受试者被分配到WBV组或同等阻力（ER）组，进行为期6周、每周3次的训练。
在训练期前后评估等速跖屈和背屈峰值扭矩、等速膝关节屈伸峰值扭矩、爆发力（高箱测试）和姿势控制。
两个训练计划均显著提高了等速踝关节和膝关节肌肉力量以及爆发力。此外，6周后，WBV组的爆发力和低速时跖屈肌力量的增加显著高于ER组。然而，WBV训练和ER训练似乎都对姿势控制没有影响。
与不包括WBV的同等计划相比，包含WBV的力量训练计划对年轻滑雪者似乎具有累加效应。因此，我们的研究结果支持以下假设：WBV训练可能是年轻运动员力量训练计划中一种有益的辅助训练技术。
