| Outline of Final Research Achievements |
This aim of this study was to investigate the effect of gastrointestinal blood flow on the digestive and absorptive activations following strenuous exercise in humans. A carbohydrate-protein drink was ingested at either 5 min (i.e., profoundly decreased celiac artery blood flow; CABF) or 30 min (i.e., already recovered CABF) post-exercise. In the 5 min post-exercise trial, the gastric emptying (GE) rate and superior mesenteric artery blood flow (SMABF) response were slower than those in the 30 min post-exercise trial. The GE rate and SMABF response may be altered depending on the post-exercise CABF response.The present data provide useful information to prevent GI distress and encourage effective recovery from physical fatigue among athletes.
