In this study, we investigated the effects of whole body vibration (WBV) training on postural balance and gait function in elite inline skaters. The study included 40 elite inline skaters who were randomly assigned to the WBV (N=20) or control (N=20) group. The movement velocity (degrees/s) in the anterior and posterior directions, as well as on the left and right sides for the limit of stability and spatiotemporal gait parameters with passive and active range of motion (ROM) of the ankle joint were recorded. WBV group participants performed WBV exercises in the vertical direction using a vibration device for 5 min, five times a week for 6 weeks. Control group participants performed the same procedure but on a stable surface. Participants who underwent WBV showed a significant increase in the anterior limit of stability (p<0.01). Both groups showed significant improvement in most gait parameters associated with ROM of the ankle joint; however, the WBV group participants showed significantly increased stride length (p<0.01) and left step length (p<0.01). WBV may serve as a potentially useful strategy to improve an individual’s ability to maintain increased anterior momentum and gait functions, which are necessary for improved performance of in-line skaters.
