Abstract

The aim of this study was to determine the acute effect of a mechanical vibrations exposure on power during vertical jump. A total of 15 active and healthy subjects (11 males and 4 females) were exposed to a 60 s period of stimulation on a vibratory platform that induced vertical oscillations (frequency: 50 Hz; amplitude: 2 mm). Subjects were asked to perform three vertical jumps (before vibratory stimulation and 30 s and 2 min. after this period) on a resistive platform where the flight time (tv) and height (h) of each single jump were recorded. The results show a positive effect of vibratory stimulus on power during vertical jump performed 2 min. after vibratory stimulation period, since tvand h were significantly highly than those registered in the first jump. It can be concluded that 60 s of whole body stimulation on a vibratory platform based on high-frequency and low-amplitude oscillations generate a positive residual effect on vertical jump.
