Response of Cerebral Circulation during Warming Up Exercise
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.5 Vol.5】
It was studied that the common carotid artery (CCA) blood flow in 3 healthy young males responded during and after the light-exercise by a bicycle ergometer, using of the quantative flow measurement system.
Main conclusions were as follows:
1. The mean CCA blood flow volume of all subjects was inclined to increase over the resting level in the exercise of work loads with 25 watt and 37.5 watt.
2. There was the significant relation (r=0.949, p<0.001) between mean blood velocity and mean blood flow volume in CCA.
3. The mean diameter of the CCA didn't much change in these three stages: before exercise, during exercise and after exercise.
