![]() ![]() Alice Thackray, a Senior Research Associate in Exercise Metabolism from Loughborough's School of Sport, Exercise and Health Sciences (SSEHS) was the lead author for the study. Using a different type of fMRI, the study team also detected changes in blood flow in the brain after exercise, although these changes did not appear to influence the food cue reactivity signals.ĭr. Researchers found that the bout of exercise suppressed how hungry participants said they felt but it increased the reactivity of multiple parts of their brain to food cues. ![]() During the scan, they were asked to look at three types of images ranging from low-energy dense foods such as fruits and vegetables to high-energy dense foods such as chocolate, as well as non-food items such as furniture. ![]() fMRI scans help us evaluate what is happening in the brain by detecting small changes in blood flow.įor this study, twenty-three men underwent fMRI scans before and after 60 minutes of running or rest. These changes can be captured using functional magnetic resonance imaging (fMRI). The study team wanted to explore whether exercise-induced blood flow changes in the brain can influence how people react to food. Food cue reactivity can have an impact on our appetite and how much we end up eating. It's the way we react (both physically and psychologically) to the sight or smell of food, for example. However, we don't fully understand the extent to which exercise impacts how likely we are to eat.įood cue reactivity is the way our body responds to food. Previous studies have shown that single bouts of exercise such as running can temporarily suppress appetite. How much we eat is influenced by systems in the brain that are sensitive to changes in our body and the food environment we are in. They found that changes in how participants responded to visual food cues happened independently of the overall changes to blood flow in the brain. Researchers from the UK's Loughborough University, University of Bristol, University of Nottingham and the University of Leicester, and Waseda University in Japan investigated the impact of running on blood flow in the brain and how this influenced brain activity in relation to appetite. ![]()
