The linear blood flow velocity and the diameter of main arteries of the lower extremities were measured before and after a 30-min bicycle ergometer exercise in 18- to 22-year-old healthy male volunteers not involved in professional sports (controls), as well as in highly qualified wrestlers and track-and-field athletes. In comparison to the control group, the track-and-field athletes have wider arteries, whereas the wrestlers have stronger muscles. The arteries become wider during the first minutes after the bicycle ergometer exercise, which is accompanied by a decrease in the linear velocity of the blood flow. The athletes, especially the track-and-field athletes, have a shorter transitional period. The arterial blood flow in an extremity shows a 20% increase in the first minutes after the test; the shortest recovery period for this parameter was found in the track-and-field athletes. |
