To examine the effect of combined exercise on colonic transit time (CTT) in admitted psychiatric patients. Over a 6-mo period, consecutive in patients with mental illness were recruited from the Somang Hospital Psychiatry Unit. A combined exercise program that included 60 min per day of exercise 3 d per week for 12 wk was performed. Physical fitness and CTT of the patients were measured twice before and twice after the exercise program. CTT was measured using a multiple marker technique with a radio-opaque marker. Changes in the exercising patients' CTT and weight-, cardiovascular- and fitness-related parameters were statistically assessed. After the 12-wk combined exercise intervention, decreased intestinal transit time was observed in all CTTs of the exercise group, including the right CTT (exercise: 15.6 ± 15.2 9.2 ± 11.9, control: 13.1 ± 10.4 10.9 ± 18.7), left CTT (exercise: 19.7 ± 23.5 10.4 ± 13.2, control: 19.2 ± 19.0 16.9 ± 19.8), recto-sigmoid CTT (exercise: 14.3 ± 16.7 6.7 ± 7.9, control: 15.0 ± 14.4 19.3 ± 30.3), and total colonic transit time (TCTT) (exercise: 50.2 ± 38.1 27.1 ± 28.0, control: 47.4 ± 34.6 47.3 ± 47.3). After the 12-wk combined exercise period, TCTT was significantly shortened in the exercise group compared with that in the control group. In addition to eating habits, water intake, and fiber intake, the increased physical activity level as a result of the 12-wk combined exercise program reduced the CTT. The CTT of the psychiatric patients was reduced due to increased physical activity a 12-wk combined exercise program.
