EVALUATION OF ELECTRO MYOGRAPHIC SIGNALS SUBMITTED TO WHOLE-BODY VIBRATION EXERCISE: CONTROLLED AND RANDOMIZED CROSS-CROSS CLINICAL TRIAL

Abstract

Introduction: Studies indicate Whole Body Vibration Exercise (EVCI) as a rehabilitation tool. The response of the muscles to fatigue, during a submaximal exercise, translates into an increase in the number of recruited motor units, which can be observed in the electromyography (EMG) signal by the increase in its amplitude. Objective: To evaluate the effects of EVCI through electromyographic signals in adult individuals. Methods: This is a block-randomized, controlled, cross-sectional clinical trial. Developed at the UNIG Physiotherapy School Clinic – Nova Iguaçu – RJ, with a population between 18 and 60 years old. 22 individuals divided into 02 groups were evaluated: Control (11) and EVCI (11). ). Results: There was evidence of an increase in muscle fiber recruitment during EVCI at 5Hz (p 0.0002), 10Hz (p 0.0009), 20Hz (p 0.0009) and 30Hz (p 0.0009). Conclusion: EMG is an effective tool for capturing signals during EVCI.
