目的：探讨轻度运动对肠道气体输送和清除的影响。方法：8例健康成人，空肠内连续注入气体混合物（12 mL/min） 120分钟，同时十二指肠脂质灌注（1 kcal/min）。在休息和间歇蹬车期间，受试者采用仰卧位，每隔15分钟测量一次气体排出、腹部感觉知觉（0[无]至6[痛]）和腹部围。结果：运动时平均（+/- SD）肠道气体潴留低于静止时(-84 +/- 303 mL vs. 143 +/- 219 mL， P
PURPOSE: To determine the effects of mild physical activity on intestinal gas transit and clearance.METHODS: In 8 healthy adults, a gas mixture was infused continuously into the jejunum (12 mL/min) for 120 minutes with simultaneous duodenal lipid perfusion (1 kcal/min). Gas evacuation, perception of abdominal sensations (on a scale of 0 [none] to 6 [pain]), and abdominal girth were measured at 15-minute intervals during rest and intermittent pedalling, with subjects in a supine position.RESULTS: Mean (+/- SD) intestinal gas retention was lower during exercise than at rest (-84 +/- 303 mL vs. 143 +/- 219 mL, P
