Abstract :
A measurement system was developed, which was able to measure synchronously blood flow velocity distributions and ECG during exercise. It was found from the results of experiments that the slower maximum blood flow velocity and the faster wave propagation time were observed for standing posture as compared with those for supine. Similarly, it was found that these became faster in proportion to work rate during walking on a treadmill
