The purpose of the study is to determine the effect of whole-body vibration (WBV) on body composition, physical fitness, and quality of life.
The purpose of the study is to determine the effect of whole-body vibration (WBV) on body composition, physical fitness, and quality of life.Twenty healthy adult males and females (ages 18-65) with no contraindications for exercise training will be recruited to participate in the study. Subjects will participate in a randomized, crossover trial for 24 weeks. Subjects will be assigned to either: (1) WBV for the first 12 weeks and then aerobic exercise training for the second 12 weeks 3 times per week (n=10) or (2) aerobic exercise training for the first 12 weeks and then WBV for the second 12 weeks 3 times per week (n=10). Subjects will be assessed at baseline and at 12 and 24 weeks on aerobic capacity (estimated VO2max), upper and lower body strength (1-repetition maximum on bench press and leg press, respectively), compartmental and total body fat mass, fat free mass, and bone mineral density (using dual energy x-ray absorptiometry (DEXA)), body mass index (height relative to weight), weight, skin fold and body part circumferences, resting blood pressure and pulse, and subjective health-related quality of life (SF-36). Participants will be trained and assessed at the University of Miami Miller School of Medicine UHealth Fitness and Wellness Center, in UHealth Champions Executive Medicine, and in the Department of Psychiatry and Behavioral Sciences.
No substantial psychological, medical, or social risks exist to the participants. Although all measures to protect confidentiality will be put in place, the possibility exists that electronic data could be jeopardized. In the remote case that such event occurs, it will be immediately reported to the Institutional Review Board (IRB).
Exercise has been shown to be safe among every population, including those with chronic diseases and/or other complications. A DEXA scan is the equivalent of about 4 extra days' worth of naturally-occurring radiation.
The use of the HyperVibe WBV training device should be harmless without any known negative effects, as WBV is even lower risk than aerobic exercise, as the participant simply stands on the platform without moving while being exposed to full-body vibration. The system is completely non-invasive, and no serious, untoward side effects have been reported to the manufacturer (HyperVibe) of this system. All study personnel will follow instructions for operating the system. Participants will incur no additional appreciable psychological or social risks by participating in this study.
The results obtained in this study may demonstrate a way to increase exercise efficiency through the use of WBV in helping overweight/obese participants to lose weight, gain muscular weight, and improve physical fitness levels. By participating in the study, subjects may improve their overall health status in a unique approach to exercise training. The minimal risk of participating in this study is reasonable because the potential information gained can be worthwhile for helping people to lose weight, which is significant, given the inordinate prevalence of overweight/obesity and its co morbid chronic diseases in the United States today.

| Whole Body Vibration training | Experimental | Use of the HyperVibe Whole Body Vibration training device for 12 weeks 3 times per week crossover to aerobic exercise |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| HyperVibe Whole Body Vibration training device | Device | Standing on the HyperVibe platform during WBV training will cause repetitive upward movements of platform to be felt by participant.Thus the participant will feel a whole body vibration, as the name of training implies. Each session will last approximately fifteen minutes. |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in body composition | Body composition will be evaluated by DEXA scan which measure fat free mass , total body and compartmental fat mass | Baseline,12 weeks and 24 weeks |
| Change from baseline in aerobic capacity | Aerobic capacity and strength will be assessed by Graded Exercise Test | Baseline,12 weeks and 24 weeks |
| Change from baseline in body strength | Overall upper and lower body strength will be assessed by one-repetition maximum strength tests | Baseline,12 weeks and 24 weeks |
| Change from baseline in bone mineral density | Bone mineral density will be assessed by DEXA scan | Baseline,12 weeks and 24 weeks |
| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in physical activity | Physical activity will be assessed with International Physical Activity Questionnaire (IPAQ). The IPAQ items are structured to provide individual domain specific scores for walking, moderate-intensity, and vigorous activity within the domains of work, transportation, domestic chores and gardening, and leisure-time. The tool asks about the time spent doing a specific physical activity in the last 7 days. For total scores, the duration (in minutes) and frequency for all types of activities in all domains are summed, while specific domain scores are calculated by the summation of the walking, moderate-intensity and vigorous-intensity activities within the specific domain. For activity-specific scores, the scores for the specific type of activity across domains are added. To measure the volume of activity, each type of activity is weighted by its energy requirement defined as the metabolic equivalent of task-minute (MET-min). |
