Comparación de diferentes ejercicios con vibración sobre el rendimiento neuromuscular
The first purpose of this study was to determine the effects of whole-body vibration (WBV) exercise during an isometric handgrip
exercise. The second purpose was to evaluate whether more than one vibratory focus would evoke an increase in the effects
evoked by only one vibratory focus. The present study investigated whether WBV exposure during 10 repetitions of a handgrip
dynamometer while standing on a WBV platform. Twenty-eight recreationally active university students completed 3 different
test conditions, in random order: 1) grip dynamometer exercise with superimposed WBV and contralateral arm vibration
(WBV+AV); 2) superimposed arm vibration only (AV); 3) grip dynamometer exercise without vibration (Control). The hand grip
strength was slightly higher in the WBV condition as compared to the Control and AV conditions (1.1% and 3.6%, p>0.05, respectively).
A main effect of the EMGrms of extensor digitorum muscle (ED) was observed indicating that the WBV+AV condition
produced a lower co-activation of ED during a flexor digital task than the Control and AV (p<0.05) conditions. The application
of WBV+AV may acutely increase muscle coordination and decreases the coactivation of ED. Furthermore, the muscle EMGrms
showed increases in activation near the vibratory focus in both upper- and lower-body.
