Abstract

The aim of the present study is to describe echocardiographically determined functional changes in Athletes, which enhance the left ventricular function and to compare them with sedentary individuals. Materials and Methods: The study was conducted on male subjects (n=50), aged between 20 and 25 years, who are non smoking and non alcoholic. First the resting values are taken in both the groups and the parameters selected for the study are End Diastolic volume, End Systolic volume, Stroke volume and cardiac output. After making the initial recording through Echocardiography of the above parameters at rest, the subject is instructed to run for 15 minutes and the respective parameters are recorded as previously. Results and Discussion: In this study, when athletes were compared with sedentary lifestyle men, there was an increase in End Diastolic volume, Stroke volume and Cardiac output both at rest and during exercise, thus enhancing the left ventricular functional capacity in Athletes. Conclusion: Regular dynamic exercise induces significant physiological adaptations of cardiac functioning, which allows higher peak working capacity , making the Athletes more work efficient than the non-exercising sedentary individuals.
