The purpose of this study was to investigate in cerebral blood flow velocity, pulsatility index, O2 uptake in various exercise intensity of Judo athletes. Twelve healthy males received the medical test and stress test. After a week, they were tested by transcranial doppler ultrasonography at stable(before exercise), moderate exercise intensity(O2max 50%), maximal exercise intensity(O2max 100%), recovery time 1-minute and 3-minute, respectively. First, systolic cerebral blood flow velocity(sCBFV) was significantly different in group and time, diastolic cerebral blood flow velocity(dCBFV) was significantly different in time and interaction, and then mean cerebral blood flow velocity(mCBFV) was significantly different in group and time. These results mean that regular exercise may increase the blood flow supply and facilitate the recovery ability in men. Second, the pulsatility Indices were significantly different in time and interaction. The pulsatility Indices of exercise group were down-regulated in maximal exercise intensity, recovery time 1-minute and 3-minute, respectively. These results mean that regular exercise may decrease the stickness of arteries and increase the circulation of body. Finally, O2 uptakes were significantly different in group, time, and interaction, respectively. At last, the O2max significantly correlated with sCBFV(r=0.680, p=0.015), dCBFV(r=0.662, p=0.019), and mCBFV(r=0.671, p=0.017), respectively. The sCBFV significantly correlated with dCBFV(r=0.846, p=0.001) and mCBFV(r=0.958, p=0.001), respectively. The dCBFV significantly correlated with mCBFV(r=0.948, p=0.001) and pulsatility Indices(r=-0.644, p=0.024), respectively. In conclusion, O2 represents the higher correlation coefficients with cerebral blood flow velocity and pulsatility index, regular exercise may enhance the blood flow velocity in exercising and recovering from maximal exercise.
