About this study
Official title: The Effects of Whole-Body Vibration, With and Without Balance Exercises, on Dynamic Postural Stability in Young Soccer Players: A Randomized Controlled Study
The goal of this randomized controlled study was to investigate the effects of whole-body vibration (WBV), with and without balance exercises, on dynamic postural stability in young male soccer players aged 18-22 years.
The main questions it aimed to answer were:
Read more
- Does whole-body vibration training improve dynamic postural stability in young soccer players?
- Does combining whole-body vibration with progressive balance exercises provide greater improvements in dynamic postural stability than whole-body vibration alone?
Researchers compared three groups: a control group (CON), a whole-body vibration group (WBV), and a whole-body vibration combined with balance exercises group (WBV+BE).
Participants:
- Were randomly assigned to one of the three groups.
- Completed an eight-week intervention period, with supervised training sessions three times per week in the intervention groups.
- Performed progressive balance exercises during vibration exposure in the WBV+BE group.
- Underwent dynamic postural stability assessments before and after the intervention using the Biodex Balance System.
Read the detailed description
Dynamic postural stability is an important component of neuromuscular control in soccer, contributing to the maintenance of balance during sport-specific movements. Whole-body vibration (WBV) training has been investigated as a method for improving postural control; however, the additional benefits of combining WBV with progressive balance exercises remain unclear.
This randomized controlled study was designed to examine the effects of an eight-week WBV training program, performed with or without balance exercises, on dynamic postural stability in young male soccer players.
Participants were randomly allocated to three parallel groups: a control group (CON), a whole-body vibration group (WBV), and a whole-body vibration combined with balance exercises group (WBV+BE). The intervention groups completed supervised training sessions three times per week for eight weeks. The WBV group received vibration exposure without additional balance exercises, whereas the WBV+BE group performed progressive balance exercises during vibration exposure.
Dynamic postural stability was assessed before and after the intervention using the Biodex Balance System. The Overall Stability Index (OSI) was used to evaluate changes in postural stability, with lower values indicating better stability.
The study was intended to determine whether WBV training improves dynamic postural stability and whether combining WBV with progressive balance exercises provides additional benefits compared with WBV alone.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Whole-Body Vibration TrainingBehavioural
Whole-body vibration training was performed three times per week for eight weeks using a Docamark Vibrapro vibration platform operating in vertical mode at a nominal frequency of 20 Hz and a peak-to-peak amplitude of 2 mm. Each session included a 10-minute warm-up followed by 12 bouts of 60 seconds of vibration exposure, with 30-second rest intervals between bouts and 60-second rest intervals between blocks. Participants performed the intervention barefoot. The same vibration parameters and exposure duration were applied in both the WBV and WBV+BE groups. In the WBV group, participants maintained a bilateral standing position, whereas in the WBV+BE group, progressive balance exercises were performed simultaneously with vibration exposure.
Balance ExercisesBehavioural
Progressive balance exercises were performed simultaneously with whole-body vibration exposure three times per week for eight weeks in the WBV+BE group. The exercises included bilateral mini squats, mediolateral weight shifts, anteroposterior weight shifts, and bilateral heel raises. During weeks 1-4, mini squats were performed at approximately 20-30° of knee flexion, with small-amplitude weight shifts and bilateral heel raises. During weeks 5-8, squat depth increased to approximately 30-40°, weight-shift amplitude was progressively increased, and heel raises included a two-second hold. The exercises were performed barefoot with eyes open, using the same vibration exposure duration as the WBV group.
| Study group | Role | What they receive |
|---|---|---|
| Control Group (CON) | No intervention | Participants in the control group (n = 12) continued their regular soccer training routines without receiving any additional whole-body vibration or balance exercise intervention during the eight-week study period. |
| Whole-Body Vibration Group (WBV) | Experimental | Participants in the WBV group (n = 12) received whole-body vibration training three times per week for eight weeks. The intervention was performed using a vibration platform operating at a nominal frequency of 20 Hz and a peak-to-peak amplitude of 2 mm. Each session included 12 bouts of 60 seconds of vibration exposure without additional balance exercises. Receives: Behavioral: Whole-Body Vibration Training |
| Whole-Body Vibration Plus Balance Exercises Group (WBV+BE) | Experimental | Participants in the WBV+BE group (n = 12) performed progressive balance exercises during whole-body vibration exposure three times per week for eight weeks. The vibration parameters were identical to those of the WBV group (20 Hz, 2 mm peak-to-peak amplitude). Exercises included mini squats, anterior-posterior and medial-lateral weight shifts, and bilateral heel raises, with progression implemented during the intervention period. Receives: Behavioral: Whole-Body Vibration Training; Behavioral: Balance Exercises |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change in Dynamic Postural Stability (Overall Stability Index)
Dynamic postural stability was assessed using the Overall Stability Index (OSI) obtained from the Biodex Balance System SD. Participants performed single-leg balance testing on their dominant leg at platform stability level 6 with eyes open. Two recorded 30-second trials were performed, and the mean OSI score was used for analysis. Lower OSI values indicate better postural stability. The primary outcome was the change in OSI from baseline to post-intervention.
Measured: Baseline (before intervention) and 48 hours after the final training session (end of week 8).
