title: A Randomized Controlled Pilot Study to Investigate the Effect of Whole-Body Vibration on Lower-Extremity Fatigue.
abstract: BACKGROUND
  Whole-body vibration (WBV) is a type of weight-bearing exercise used in the field of sport and rehabilitation. There is no study on the effects of WBV on muscle recovery after a fatiguing activity.
  
  
  OBJECTIVE
  To determine the effects of a single WBV session on lower-extremity fatigue.
  
  
  METHODS
  Randomized controlled pilot study.
  
  
  METHODS
  University Physiotherapy Clinic.
  
  
  METHODS
  A total of 13 healthy young men volunteered to participate in this study. Subjects were randomly assigned into the WBV group (n = 7, mean age: 21 y) or control group (CG; n = 6, mean age: 20 y).
  
  
  METHODS
  Subjects in the WBV group participated in a single-session WBV (30 Hz, amplitude 4 mm, 2 min) after lower-extremity fatigue.
  
  
  METHODS
  Peak force of quadriceps muscle, single leg hop test, and Y-test were measured before inducing muscle fatigue (T0), immediately after completing the fatigue protocol (T1), after WBV (T2), and 15 min following the application of WBV (T3). The same method was applied in the CG while the WBV machine was turned off.
  
  
  RESULTS
  Repeated-measure ANOVA revealed no significant differences between groups in any of the outcomes.
  
  
  CONCLUSIONS
  The findings indicated that WBV was not effective in the recovery of lower-extremity fatigue in healthy young men.
