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.

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.
