A decrease in arterial compliance or an increase in arterial stiffness is common with advancing age and it is a predictor of cardiovascular risk factors. Epidemiological studies have found that physically active person have lower prevalence of cardiovascular disease compared to sedentary, it has been reported that agerelated increases in central arterial stiffness are absent or attenuated in endurance-trained adults. The purpose of this study was to estimate the indexes of aortic elasticity in the sportsperson and the correlation between them and left ventricular mass index. This study was carried on 46 sportsperson, their mean age of 31.3 + or - 11.4 and compared with the sedentary healthy control group of 60 people. They are all under echocardiography to measure systolic aortic diameter and diastolic aortic diameter, left ventricular mass, and left ventricular mass index. Then, assess the indexes such as: aortic strain, aortic stiffness, aortic distensibility and correlation between them and left ventricular mass index. The results showed that aortic strain and aortic distensibility were significantly higher in the active group compared with those in the sedentary people. There was no difference in aortic stiffness index between the sportsperson and healthy sedentary group. There were positive correlation between left ventricular mass index and both aortic strain and aortic distensibility. In contrast, there is no correlation between aortic stiffness and left ventricular mass index. Thus, physical activity may have beneficial effects on arterial elasticity, therefore reducing the risk of cardiovascular disease.
