Abstract

Radiography and xerotomography of the chest in highly trained endurance sport athletes has revealed a marked increase in pulmonary vascularization especially in the upper regions of the lungs. On the basis of these observations (asa condition of increase of regional blood flow) the authors studied by scintigraphy the pulmonary blood flow distribution of athletes at rest and after submaximal exercise and have compared the results with those of non athletic subjects. The scintigraphic data show that athletes in rest conditions have a higher percentage of blood flow distribution in the right lung (58 ) than in the left (42 ) while in sedentary subjects the difference between right (52)and left (48 ) is less. Along the vertical axis of the lung, both in athletesand in non athletes the blood flow is distributed in the same percentage at the level of the upper and middle third; at the level of the lower third the differences are not significant. In confirmation of these results the index of perfusion presents a similar trend in the two groups of subjects. On the basis of these results, the authors conclude that in athletes trained for endurance sports, compared with non athletes, there exists a different anatomo-functional condition of pulmonary vascularization.
