摘要：

Several studies have indicated that vibratory training can contribute to the development of muscle strength and sports performance. The aim of this study was to investigate the effect of mechanical vibration application in the direction of the result of muscle forces vector addition on vertical jump. Eighteen volunteers performed vertical jump test 20 s before and after the application of mechanical vibration of 20 Hz and 6 mm amplitude in the direction of the result of muscle forces vector addition. The same volunteers were used as control group by performing the vertical jump test without pre- and post-test vibration application. The vibratory training caused an significantly increase of 8,5% at vertical jump height while jump height did not vary significantly in the control experiment. These data suggest that the application of mechanical vibration in the direction of muscle forces vector addition can increase the performance in vertical jumps.
