Study of Exercise Subscription in the Human Common Carotid Artery Blood Flow by the Quantitative Flow Measurement
【Supercategory：7. DESCENTE SPORTS SCIENCE Subcategory：7.2 Vol.2】
This study was undertaken in order to investigate the response of the cerebral blood circulation system to the effects of a number of exercise-load levels-(2 kp, 2.75 kp and 3.5 kp). We were able to develop the ‘non-invasive’ method of measuring the blood flow in the common carotid artery under normal conditions by using the Quantitative Flow Measurement. The following results were obtained;
1) Blood volume flow increased for 60 seconds immediately after cessation of exercises in proportion to the level of exercises.
2) Blood flow velocity was constant at every level. It increased slightly for 60 seconds immediately after cessation of the 2.75 kp load and the 3.5 kp load, but not significantly.
3) Blood pressure increased during and after exercise, however cerebral circulation resistance always increased with blood pressure. This phenomenon suggested a possible auto-response control to regulate blood volume in the brain.
