Title

COMPARISON OF THE IMMEDIATE AND SHORT TERM (12 SESSIONS) EFFECTS OF WHOLE BODY VIBRATION ON THE SPINAL MOTOR NEURONS EXCITABILITY IN HEALTHY YOUNG MEN

Pages

  46-54

Abstract

 Background and Aim: Despite the widespread use of WHOLE BODY VIBRATION (WBV),especiallyin recent years, its neurophysiological mechanism is still unclear and the results about the facilitatory or inhibitory effects of WBV widely vary in different studies. The aim of this study was to compare between immediate (one session) and short term (12 sessions) effects of WBV on the spinal motor neurons excitability in healthy young men.Materials and Methods: Ten voluntary non-athlete healthy young-men (mean age: 26.1±2.23) were participated in this study. In the sham sessions subjects stood on the turned off vibration plate while were maintaining the semi-squat position and then after 2 weeks wash-out, vibration training sessions were done on the same position with frequency of 30 HZ and peak to peak amplitude of 3 mm training sessions (sham d vibration) consisted of 12 sessions (3 sessions per week) and 4 set in each of them, weekly one set added to the training protocol. H REFLEX RECRUITMENT CURVE of SOLEUS MUSCLE was recorded before and after first and also 12 th sessions in both sham and vibration training protocol. Ascending slope of recruitment curve, threshold and peak amplitudes and related intensities, amplitude of Mh and Hmax/Mmax ratio were determined.Results: Immediate effects of vibration training 12th session caused a significant decrease of threshold amplitude and an increase of peak intensity (p=0.05 and p=0.05 respectively). Short term WBV training significantly decreased the threshold intensity of soleus recruitment curve (p=0.01).Conclusion: The results suggest the inhibitory effect of acute WBV training on the spinal motor neurons excitability. It seems that short term WBV training may be effective to facilitate the motor neurons excitability or increase the muscle spindle sensitivity.
