    Abstract:
    AIMS: Currently, it remains unclear whether there are differences in the long-term physiologic and adaptive changes in an athlete's heart, varying by the type of exercise undertaken. In this study, we used standard and speckle tracking echocardiography (STE) to evaluate the long-term effects of cardiac remodeling, which persisted many years after retiring from professional sports (marathon running and wrestling). METHODS AND RESULTS: Twenty-four marathon runners, 25 wrestlers, and 24 healthy subjects were included in the study. Left ventricular (LV) strain (S) and strain rate (Sr) were evaluated by apical two- (2C), three- (3C), and four-chamber (4C) imaging. Global S and Sr were calculated by averaging the 3 apical views. The participants' mean age was comparable across the 3 groups. Weight, body mass index, LV mass, LV mass index, and relative diastolic wall thickness were higher in wrestlers than the other groups (P < 0.001). Systolic and diastolic functions, evaluated using conventional echocardiography, were comparable among the 3 groups. 2C, 3C, and 4C longitudinal strain (LS), global LS (GLS), and global Sr systolic filling (SrS) values were comparable between the marathon runners and control group; however, GLS, LS-2C, GLSrS, SrS-3C, and SrS-2C values were significantly increased in wrestlers compared with the control group. CONCLUSIONS: Myocardial changes in wrestlers and marathon runners who quit sports after an extensive period were evaluated using standard echocardiographic and STE parameters. Although they had stopped playing active sports more than 10 years earlier, both the structural and functional properties of the heart were maintained in wrestlers.
