Abstract: Background: Whole body vibration was an effective training for improving muscle performance. The purpose of this study was to explore the effects of 12 week whole-body vibration training program on voluntary activation of quadriceps muscles of older people with age-related muscle loss (sarcopenia).
Methods: Twelve community dwelling seniors with age-related muscle loss were randomly allocated into whole body vibration training group and control group. The training lasted for 12 weeks. Twitch interpolation were conducted to examine the voluntary activation of quadriceps at pre- and post-intervention.
Results: Although there was no significant difference between whole body vibration training group and control group on the absolute values of the interpolated twitch ratio after 12 weeks of training. The changed values of ratio (Post minus Pre) were significantly different between the two groups (p = 0.044).
Conclusions: The voluntary activation of quadriceps muscles of older people with age-related muscle loss was facilitated after 12 weeks of WBV training with 40 Hz x 4 mm x 360 s. Considering the small sample size of this study, it may only provide a piece of evidence that WBV is effective for facilitating the central motor drive in seniors with age-related muscle loss. More subjects are needed to confirm the present finding.
