Exercise can help smokers quit because it makes cigarettes less attractive. A new study from the University of Exeter shows for the first time that exercise can lessen the power of cigarettes and smoking-related images to grab the attention of smokers. The study is published in the journal Addiction.
The study involved 20 moderately heavy smokers, who had abstained from cigarettes for 15 hours before the trial. During two visits to our laboratory participants began by being shown smoking-related and neutral images, and then spent either 15 minutes sitting or exercising on a stationary bike at a moderate intensity. Afterwards, they were again shown the images.
While the participants were shown the images, the research team used the latest eye tracking technology to measure and record their precise eye movements. They were able to show not only the length of time people looked at smoking-related images but also how quickly pictures of cigarettes could grab their attention, compared with non-smoking matched images.
The study showed an 11% difference between the time the participants spent looking at the smoking-related images after exercise, compared with the after sitting. Also, after exercise, participants took longer to look at smoking-related images. Exercise, therefore, appears to reduce the power of the smoking-related images to grab visual attention.
