- The gadgets, which can cost £1,200, send vibrations through the entire body
- Researchers found that the mimic the muscle strength benefits of a brisk walk
- However, the popular machines prevent anyone from ever breaking into a sweat
Trendy exercise machines that simply vibrate the body are just as good at burning fat as running, scientists claim.
The devices, which range from £165 to £1,200 – send vibrations throughout the entire body, mimicking traditional exercise.
They are growing increasingly popular among adults who haven’t got the time or motivation to run, cycle or visit the gym.
And the latest study on mice shows that they are on par with treadmills in helping to achieve weight loss.
Professor Meghan McGee-Lawrence, of Augusta University in Georgia, said: ‘Our study is the first to show whole-body vibration may be just as effective as exercise at combating some of the negative consequences of obesity and diabetes.
‘While WBV did not fully address the defects in bone mass of the obese mice in our study it did increase global bone formation – suggesting longer-term treatments could hold promise for preventing bone loss as well.’
Adults can sit, stand or lay down on a vibrating platform. When the machine is switched on it transmits energy to the body.
This causes the muscles to contract and relax involuntarily multiple times every second – simulating conventional exercise with no exertion.

To test their effects, researchers assigned two groups of rodents to three separate measures: the vibration devices, treadmills or no exercise.
One set of mice were deemed normal, while the others were genetically engineered to be unresponsive to the hormone leptin – which promotes feelings of fullness.
The animals were weighed every week of the three month experiment which was published in the journal Endocrinology.
The researchers found the genetically obese mice showed similar benefits from the vibrating devices and exercising on the treadmill.
Both activities also strengthened their muscles, and boosted their insulin sensitivity – protecting them from diabetes.
The researchers are now calling for trials in human patients. Professor McGee-Lawrence said: ‘These results are encouraging.
‘However – because our study was conducted in mice – this idea needs to be rigorously tested in humans to see if the results would be applicable to people.’
