From: Gastric transit and small intestinal transit time and motility assessed by a magnet tracking system
Small intestinal contraction frequency during fast and postprandially (example from investigations in one subject). The progression in the small intestine is on the x-axis, and the contraction frequency in the small intestine for two hours after pyloric passage is on the y-axis. In general, the mean contraction frequency was lower during fast compared to postprandially (9.48 min-1 vs. 10.25 min-1). The decrease in contraction frequency per 2 hours was smaller during fast when compared to postprandially (-0.18 Hz cm-1 vs. -1.45 Hz cm-1).
