EFFECT OF WHOLE BODY VIBRATION ON THE ELECTROMYOGRAPHIC ACTIVITY OF CORE STABILIZER MUSCLES: WBV ON CORE STABILIZER MUSCLES

Abstract Objective To analyze the effects of whole body vibration on electromyographic activity of the core muscles. Methods This is an observational cross-sectional study composed of 30 males who practice physical activity. The amplitude of the electromyographic activation (Root Mean Square - RMS) of the rectus abdominis, external oblique, longissimus thoracis, multifidus muscles were evaluated during supine bridge, side plank and frontal plank exercises, performed with and without vibration (frequency: 50Hz and amplitude: 4mm). A significance level of 5% was assigned for all analyzes. Results Whole body vibration did not alter the amplitude of electromyographic activity for any of the evaluated muscle groups, showing no difference between the conditions with and without vibration during the performance of the proposed exercises. Conclusion Under the conditions analyzed in this study, the vibrating platform does not change the activation amplitude of core muscles, suggesting that the use of whole body vibration is not necessary as an additional method to increase muscle activity during stabilization exercises in healthy men.
