Does physical exercise influence bowel transit time in healthy young men?

An examination was performed on 20 healthy men, who had a specific diet, to test the influence of moderate physical activity on bowel transit. During a 3-day pause and a 3-day phase of easy sports activity (jogging), oro-anal transit was measured with the help of radiopaque markers (Hinton method)....

Summary:An examination was performed on 20 healthy men, who had a specific diet, to test the influence of moderate physical activity on bowel transit. During a 3-day pause and a 3-day phase of easy sports activity (jogging), oro-anal transit was measured with the help of radiopaque markers (Hinton method). While the subject was under exertion, the entire weight of stool rose significantly (743 vs. 600 g), whereas we found no significant influence on the oro-anal transit time (39 vs. 48 h) or on stool frequency (1.3 vs. 1.3 per day). Moderate physical activity had no effect on bowel transit time of healthy men under a constant diet. The effect of the so often recommended increase of physical activity on constipation remains to be elucidated.
