Displacement and frequency for maximizing power output resulting from a bout of whole-body vibration
The aim of this study was to investigate the acute effects of different displacement and frequency of a single bout of vibration on the power performance in a countermovement jump. 20 moderately trained athletes participated in this study. The 30Hz conditions (regardless of displacement) resulted in significantly higher peak power performance compared with the 35 and 40Hz conditions, but not with the 50Hz condition. A significant higher peak power was seen 1 minute post treatment compared with the other time points (pre, immediately, 5 and 10 minutes post treatment).Conclusion:
The results of this study demonstrate the effectiveness of 30Hz frequency in improving power performance, regardless of displacement. The data also indicate that the maximal athletic performance should occur approximately a minute after the application of the Power Plate® machine intervention.
