%X Purpose: Quantify changes in blood flow velocity in radial artery after local dynamic exercise and compare these results between a group of women and men. Acquire data of normal resting blood flow in radial artery. Methods: We examined 42 healthy young volunteers (21 men and 21 women) of the age about 20. A pocket Doppler ultrasound device was used for measurements. Physical exercise was defined as one-minute-long, one-handed weightlifting. Hemodynamic parameters were registered during resting before exercise and immediately after exercise. Results: Resting baseline values: overall maximum blood flow velocity 26.49 cm/s (SD: 9.99 cm/s), mean blood flow velocity 8.46 cm/s (SD: 6.17 cm/s), and pulsatility index (PI) 5.46 (SD: 5.7) for the whole group. Mean percentage increase of maximum blood flow velocity is 36.5 %, mean blood flow velocity 243 %. PI was reduced by 52.8 %. There was a presumed significant difference in the percentage change of PI between the group of women and men (p<0.05). . There is also a typical change in velocity waveform after exercise. Conclusion: The most altered parameter is mean blood flow velocity, which corresponds to observed change of velocity waveform probably caused by local vasodilatation lasting only for several seconds
