Outline of Final Research Achievements

Irritable bowel syndrome (IBS) is characterized by central nervous system to processing visceral and somatic information recurrent abdominal pain and altered bowel habit. IBS symptom is known to reduce by exercise intervention. This study was tested effect of exercise for 4-week in 18 people with IBS and 10 asymptomatic participants and inspected the hypothesis that improvement and the desensitization of gastrointestinal symptoms produced. Results of gastrointestinal symptoms were significantly improved in high-locomotor activity group (more than 1,000 steps/day) than low-locomotor group. There were no significantly changes in somatic perception by exercise intervention in the both group. No difference of somatic perception was found on behalf of the difference in gastrointestinal symptom kept a 4-week momentum than 7,000 steps in IBS. These mechanisms should be demonstrated by analysis of the visceral and somatic information processing in human brain.
