We investigate neural activation of physical exercise related pictures in exercise addiction. Our results demonstrate that exercise addiction group showed lower activation in ventral striatum than the moderate exercise group, indicating that dopamine release of the ventral striatum in exercise addiction group may reduce because of withdrawal symptoms and negative prediction error. Moreover, we found that exercise addiction group showed less activation in the posterior orbitofrontal cortex than the other groups, suggesting that exercise addiction group may not deliberate fitness equipment and body shape of exerciser as reward value.
