Transcutaneous Doppler ultrasound was used to assess the effects of exercise on both fasting and postprandial superior mesenteric artery blood flow. After treadmill exercise (speed 5 km/h, gradient 20%, duration 15 min) in 16 subjects, superior mesenteric artery blood flow decreased by 43% immediately after the end of the exercise and by 29% at five minutes and 24% at 10 minutes postexercise. The superior mesenteric artery blood flow response to a combination of a treadmill exercise and a liquid meal in 15 volunteers was significantly smaller at five minutes from the end of the stimuli, than the response to the meal alone (15 controls) (635 +/- 51 ml/min v 846 +/- 72 ml/min) (p less than 0.025), but not different at any other time. Thus exercise reduces mesenteric blood flow in both the fasting and postprandial state in normal subjects.
经皮多普勒超声用于评估运动对空腹和餐后肠系膜上动脉血流的影响。16名受试者在进行跑步机运动（速度5公里/小时，坡度20%，持续时间15分钟）后，运动结束后即刻肠系膜上动脉血流减少43%，运动后5分钟减少29%，运动后10分钟减少24%。15名志愿者在进行跑步机运动和流食混合刺激后，刺激结束5分钟时肠系膜上动脉血流反应明显小于单独进食（15名对照者）（635±51毫升/分钟对846±72毫升/分钟）（p<0.025），但在其他任何时间均无差异。因此，运动可降低正常受试者空腹和餐后状态下的肠系膜血流。
