The immediate effect of physical activity on ultrasound-derived venous reflux parameters

ConclusionsVenous reflux decreases within 1 minute after the end of the exercises. Reduction of the volume of retrograde flow occurs only owing to the shortening of reflux time, and not the flow rate, suggesting that venous reflux is influenced by exercise-induced changes in the volume of the venous reservoir.
