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.

Abstract
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.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
