The venous flow physiology in the athletes represents an interesting research field of sports angiology. The frequent observation of phlebectasias and/or varicose veins in athletes incited us to investigate the venous pathophysiological mechanisms predisposing them to such diseases. The maximal venous outflow (Rmax in millivolts) and the 1/2 venous refilling time (1/2 VRT in seconds) were evaluated in track racers, at rest and after exercise, by means of the light reflexion rheography (LRR). Thirty-two athletes (16 males, 16 females; mean age 23.4 years, range 15-37) were studied, dividing them in three groups: (A) 100 m (13), (B) 2,000 m (13), (C) 6 x 100 m with 2 minute recovery time (6). Among them six athletes performed the test wearing elastic compression stockings (25-32 mmHg). The results demonstrated a significant post-exercise modification of LRR curves and parameters in all groups, testifying superficial venous flow augmentation and deep venous flow overloading.
