Is whole body vibration a good way to lose weight and improve fitness?

Answer

from Edward R. Laskowski, M.D.

Whole body vibration can offer some fitness and health benefits, but it's not clear if it's as good for you as regular exercise.

With whole body vibration, you stand, sit or lie on a machine with a vibrating platform. As the machine vibrates, it transmits energy to your body, forcing your muscles to contract and relax dozens of times each second. You may feel as if you're exerting yourself when you do whole body vibration. You may find a whole body vibration machine at a local gym, or you can even buy one for home use.

Advocates say that as little as 15 minutes a day of whole body vibration three times a week can aid weight loss, burn fat, improve flexibility, enhance blood flow, build strength and decrease the stress hormone cortisol.

But comprehensive research about whole body vibration is lacking. It's not yet clear if whole body vibration provides the same range of health benefits as exercise you actively engage in, such as walking, biking or swimming. Some research does show that whole body vibration may help improve muscle strength and that it may help with weight loss when you also cut back on calories.

Whole body vibration also may have a role beyond sports and fitness. Some research shows that whole body vibration, when performed correctly and under medical supervision when needed, can:

• Reduce back pain
• Improve balance in older adults
• Reduce bone loss

Still, if you want to lose weight and improve fitness, enjoy a healthy diet and include physical activity in your daily routine. If you choose whole body vibration, remember to do aerobic and strength training activities as well. And because whole body vibration can be harmful in some situations, check with your doctor before using it, especially if you're pregnant or have any health problems.
