EFFECT OF DYNAMIC EXERCISE IN CARDIAC EJECTION FRACTION IN BOTH ATHLETES AND SEDENTARY INDIVIDUALS

Background and introduction: Regular Dynamic (Aerobic) exercise induces significant physiological adaptations of cardiac functioning in comparison to non exercising (Sedentary life style) individuals. This dyn amic exercise showed complex cardiovascular physiological adaptations which allowed higher peak working capacity w ith a lesser heart rate, saving energy hence making it more efficient than in the controls. Materials and Methods: In the present study was conducted on male subjects, their age ranging from 20-25 years, who are non smoking and non-alcoholic. Results: The heart rate decreased in the athletes when compared to the sedentary individuals both at rest and during exercise, increasing diastolic filling time, increased ventricular mass and ventricular end d iastolic volume, thus enhancing the left ventricular functional capacity. Conclusion: Dynamic exercise which brings changes in serum lipoprotein levels, reducing the risk of coronary artery disease, serum glucose levels and total peripheral resistance which in turn reduces the risk of Diabetes mellitus and Hypertension respectively. Hence physicians should not only focus on smoking habits, d iet, weight and medications, but also advice regular aerobic or dynamic exercise which increases cardiovascular efficiency, mental alertness and physical fitness.
