Abstract
Athletic training may cause important structural and functional changes at the myocardium. Its effect on the vascular tree has not been documented. This study aimed to examine the large (C1) and small artery (C2) elasticity indices in 11 athletic men well trained for more than 5 years (mean age 24±1.7 years) versus 13 age-matched healthy sedentary subjects. C1 and C2 were derived from from arterial waveforms detected non-invasively at the radial artery, using the modified Windkessel model of Goldwyn-Watt. The results are summarized in the following table. We conclude that in athletic subjects large artery elasticity index is higher than in control subjects. These results suggest that athletic training may enlarge large artery elastic behaviour which has a favourable effect on the ventricular outflow.
