Pathophysiology of Cardiac Output in Athletes and Non- Athletes
Sharad Mittal, Mahendra Kumar Jaiswal

Background: Overall cardiac function that includes both, flow  and pressure generating capacities of the heart are known as cardiac output. Athlete heart can be differentiated morphologically depending on the time of exercise performed. Aim: To assess pathophysiology of cardiac output in athlete and non athlete. Method: A total of 200 subjects were selected for present study. Of the 200 subjects 100 were athletes and 100 were non athletes. The samples selected were aged between 18 to 45 years. Cardiac Output was calculated at rest and after exercise. Measures of hemodynamic status, cardiac structure and pumping capability were assessed by echocardiography. Results: Work rate at peak exercise was higher for athletes than as compared to non athletes.  A significant difference was observed between work rate and peak exercise i.e. p<0.01. Conclusion: Cardiac pumping capacity was found to be higher in athletes than in non athletes. A stronger heart pumps more blood with less effort. Athletes showed lower systolic blood pressure. Further research is warranted for the same.
Key words: Cardiac output, athlete, exercise, echocardiography.
