| Outline of Final Research Achievements |
The aim of this study was to clarify the effects of physical exercise and motor imagery on pain sensitivity/central sensitization and mood. A single bout of low-intensity exercise reduced pain sensitivity, and repetitive exercise reduced pain sensitivity for 2 weeks and central sensitization for 3 weeks. Motor imagery also resulted in hypoalgesia, as in actual exercise. Prolonged exercise for 2 hours increased elation at first and sedation later, although there was no change in pain sensitivity following exercise. These findings suggest that repetitive exercise for more than 3 weeks could activate the central pain modulation system responsible for exercise-induced hypoalgesia, prior to the improvement of subjective pain symptoms in chronic pain conditions.
