Many people do not currently undertake the necessary amount of physical activity to benefit their health.

If people could see the positive effects of being physically active on their health today, such as changes to their glucose levels, we believe this could nudge them to change their behaviour.

The Sensing Interstitial Glucose to Nudge Active Lifestyles (SIGNAL) study collected physical activity and glucose data over a period of two weeks and looked at how people responded to their personalised information using functional magnetic resonance imaging (fMRI), a tool able to monitor patterns of brain activation in response to information. Brain imaging has the benefit of giving researchers an objective view of whether the information will likely change behaviour as it is thought that the brain activation is a truer representation than self-report.

This work is being undertaken by researchers within the Movement Insights Lab.
