Abstract

Background: Athlete’s heart is a term used to describe physiological changes in the hearts of athletes.There are documented data in adults on physiological changes to athletic training but less is known in children and in particular the developing pediatric athlete. This study aims to improve our understanding of the effects of sport on the developing heart in adolecents.

Methods: In a case-control study done in Mashhad, Iran in 2018 , 60 male adolescent athlete and 60 healthy individual as controls were entered. All subjects were examined by a pediatric cardiologist using a echocardiography to compare tissue doppler Echocardiographic indices between case and control groups. Data analysis was done Using SPSS.20 .The significance level was<5%.

Results: There were no differences in age,weight, height, heart rate and fractional shortening.at baseline. The Body Mass Index (BMI) , Systolic Blood Pressure (SBP) in athletes was lower and Ejection fraction (EF) was greater in athletes than of controls. Univariate analysis of Mitral waves, showed that athletes presented greater A,E and E/E` ratio than controls and E` and S are greater in controls than athletes. In relation to septal waves, only E` was greater in controls than athletes. In relation to tricuspid waves A,E, E`/A`ratio and E/E` ratio were greater in athletes than in controls.



Conclusions: More knowledge of the pathophysiology of cardiac adaptation with training is still needed to optimize diagnosing and distinguishing sever adaptation to training from the early stages of some heart diseases.
