MOST us of us have probably, at least on our laziest days, dreamed of being able to increase our fitness without lifting a finger.

Well, that dream may soon be realised, thanks to a new technology currently in development in the UK.

Researchers at the University College London and Queen Mary University of London recently tested a small device that clips to the outer ear and sends gentle electrical pulses to increase the activity of the vagus nerve, which plays a key role in regulating heart function.

In a study involving 28 healthy volunteers, half were given the device to wear for 30 minutes per day while the other half were given dummy devices.

In subsequent tests, the researchers found that those who had worn the nerve stimulator were able to exercise at a greater intensity than the control group.

Additionally, those who wore the devices saw increases in their oxygen intake, maximum breathing rate and maximum heart rate during physical activity.

Blood sample results also suggested wearing the device helped reduce inflammation.

While more studies are needed, the researchers said they hope the new technology could eventually be used to improve wellbeing and quality of life for inactive people, as well as people with heart failure.
