Carotid artery blood flow velocity which reflected cerebral blood flow under physical exercise was measured by the ultrasound Doppler method, and the electrocardiogram(ECG) was measured simultaneously. Results : (1)The result of the simulation of the sound field distribution showed that the flow distribution waveform of the ultrasound probe might be considered on the assumption of the transposition of the blood vessel under exercise in order to deal with the transfer of right and left or top and bottom. (2)The crystal-oscillator circuit was solved by using IC type filter circuit and Gilbert multiplication type circuit in this by using Gilbert cellular demodulation circuit and band-pass filter for oscillation circuit in the detection circuit. (3)It was indicated that it could be applied to the early detection of cardiovascular disease from the difference the discipline person and the non-discipline person for the maximum blood flow velocity and for ECU pattern during physical exercise test. (4)It was recorded that the change of the blood flow velocity increased under increment load of exercise and that it decreases in the decrement load. However, maximum blood flow velocity component of carotid artery was almost fixed during a measuring time. It is guessed that the self-regulation of cerebral blood flow sufficiently works on this in the exercise of this degree. Through the measurement by this equipment, it was proven that large effect was not caused circulatory system including the brain in the exercise test by the total of these results. (5)It was measured that the fluctuation of arterial blood pressure and heart rate changed by change of the attitude and exercise. However, carotid artery maximum blood flow velocity under these exercise confirmed that the change with the meaning was not produced in the healthy examinee. It can be expected that the establishment of the safe prescription for health based on this knowledge is attempted.

通过超声多普勒方法测量了体育锻炼下反映大脑血流的颈动脉血流速度，同时测量心电图（ECG）。结果：（1）声场分布的仿真结果表明，在锻炼中血管的换位时，可以考虑超声探针的流动分布波形，以处理右，左或底部和底部的转移。 （2）通过使用IC类型滤波器电路和吉尔伯特乘法类型电路求解晶体振荡器电路，并使用吉尔伯特细胞解调电路和带通滤波器在检测电路中进行振荡电路。 （3）表明，它可以从学科人和非学科人的差异中的早期检测到心血管疾病的早期检测，以最大的血流速度和在体育锻炼测试中的ECU模式。 （4）记录在运动载荷下的血流速度的变化增加，并且在减少载荷中减少。但是，在测量时间内，几乎固定了颈动脉的最大血流速度成分。可以猜测，在行使这一程度上，脑血流的自我调节足以实现这一目标。通过该设备的测量，证明并未通过这些结果的总和在运动测试中引起循环系统效应。 （5）衡量的是，动脉血压和心率的波动随着态度和运动的改变而改变。然而，这些练习下的颈动脉最大血流速度证实，其含义的变化不是在健康的考生中产生的。可以预期，试图基于这些知识建立安全的健康处方。
