In this study, we investigated the effects of whole body vibration (WBV) training on postural balance and gaitfunction in elite inline skaters. The study included 40 elite inline skaters who were randomly assigned to theWBV (N=20) or control (N=20) group. The movement velocity (degrees/s) in the anterior and posteriordirections, as well as on the left and right sides for the limit of stability and spatiotemporal gait parameterswith passive and active range of motion (ROM) of the ankle joint were recorded. WBV group participantsperformed WBV exercises in the vertical direction using a vibration device for 5 min, five times a week for6 weeks. Control group participants performed the same procedure but on a stable surface. Participants whounderwent WBV showed a significant increase in the anterior limit of stability (p<0.01). Both groups showedsignificant improvement in most gait parameters associated with ROM of the ankle joint; however, the WBVgroup participants showed significantly increased stride length (p<0.01) and left step length (p<0.01). WBVmay serve as a potentially useful strategy to improve an individual’s ability to maintain increased anteriormomentum and gait functions, which are necessary for improved performance of in-line skaters.
