Whole body vibration (WBV) has been suggested as an effective, alternative approach to moderate intensity exercise. Vibration causes instability throughout the body which stimulates stabilization muscles to contract, thus increasing energy expenditure (EE). PURPOSE: To evaluate EE while standing and while exercising on a WBV platform. METHODS: Fourteen healthy subjects (6 male/8 female) consented to participate in this IRB-approved study (18-29y; 71.8 + 8.6 kg; 169.0 + 7.6 cm). Participants completed four conditions in four-minute stages on the WBV platform separated by four minutes of rest. Condition 1: standing, no vibration; Condition 2: standing, with vibration; Condition 3: standing, wearing a vest loaded with 20% body weight, with vibration; Condition 4: wearing a vest loaded at 20% body weight while performing half-squats (15 squats in 30 sec, 30 sec rest), with vibration. Shoes were worn at all times. Oxygen consumption was measured using a wireless, wearable metabolic system which measured breath-by-breath VO2 . EE (kcal/min) was averaged for the last minute of each condition and rest period and analyzed for differences over time using a one-way ANOVA with repeated measures at p0.05), with the exception of the values between Conditions 2 and 3 (p
