BACKGROUND: The workplace is a suitable place for the introduction of health-orientated physical activity interventions. Study goal is to determine if workplace-based whole-body vibration (WBV) training for 6 months improves basic physical abilities, daily physical activity and health-related quality of life of office employees.
METHODS: A total of 119 subjects (78% female, mean age 41.6±9.8 years, mean BMI 25.4±4.1 kg/m2) were randomly allocated to an intervention group (INT, N.=60) and a control group (CON, N.=59). The INT participated in WBV training 2.5 times per week for 6 months. At the beginning and directly after the intervention period, data were collected using jumping mechanography, progressive isointernal lifting evaluation, static posturography, and the questionnaires SF-36 and Freiburger Activity Questionnaire.
RESULTS: There were no significant differences between the groups regarding mean change from baseline in any of the outcome parameters. No improvement was observed from baseline compared to 6 months later in both groups. However, we found a trend (P=0.062) regarding a positive effect of the intervention on the maximum jumping height in the INT. The overall attendance rate was 71.6%. No unwanted side effects were detected.
CONCLUSIONS: We showed that WBV training is a safe and feasible intervention in workplace health promotion but had no significant effects on the measured parameters of the study population. The lack of effectiveness of WBV training might be due to possibly suboptimal individually configured training parameters. It seems that this intervention is ineffective as a stand-alone primary preventive intervention.
