A brief whole-body vibration intervention to avoid weight gain in college students: A randomized controlled pilot trial.

Over one-third of college students are overweight or obese and rates are rising. Whole body vibration (WBV) training could prevent weight gain but has not been tested in college students. Methods: Randomized controlled trial comparing thrice weekly WBV for 6 months to controls (CON) in undergraduate students. Feasibility included retention, adherence and safety and outcomes included changes in weight, body mass index (BMI) and fat mass. Results: 77 students enrolled in the trial (WBV: n = 40, CON: n = 37), 81% completed the study. Adherence to WBV averaged 59%. Average group differences were 1% body fat (p = 0.049) and 1 kg fat mass (p < 0.01), favoring WBV. Among students completing >80% of prescribed WBV sessions significant group differences widened, while group differences in BMI (p = 0.026) and weight (p = 0.02) change became significant. Conclusions: WBV may be a feasible, safe and effective approach to weight management in college students, though strategies to optimize adherence should continue.
