Abstract: In order to elucidate the Negative phase of systoric blood pressure after the long time running, university athletes (6 males) were participated long distance running for about two hours. The examination items were dicrotic index (DI) that expresses caliber of peripheral vessels, elastic rate of peripheral vessels (ER), impedance index of vessels (VII), impedance of peripheral vessels (W), blood pressure and body weight. The results were summarized as follows. Systoric blood pressure (SBP) reached to highest value at 30 minutes of running and gradually decreased from this time regardless of constant of vasodilatation. Since the changes of SBP and body weight was parallel, a cause of decreased SBP was considered decrease of plasma volume on sweating i. e. decrease of stroke volume. And, SBP already fall into Negative phase of 8 minutes of recovery. It was considered that this cause was decrease of stroke volume and due to continue vasodilatation, as DI kept on decrease during re-covery. On the method for calculation of characteristlcs index of peripheral vessels, in spite of the methods of measurement was difference, W was showed sametendency as DI and VII. Therefore, it was proved that both methods was useful.
