Megjegyzések:	Background Physiologic remodeling due to repetitive overload induced by exercise training is a known feature in the athletes' heart including significant changes in left ventricular (LV) deformation mechanics. The aim of the present study was to investigate three-dimensional speckle-tracking echocardiography- (3DSTE-)derived LV strains in elite athletes doing high dynamic sports with different grades of static components of their training. Methods The athlete group comprised 67 subjects (mean age: 23.6?6.4 years, 50 men). The following groups were created regarding their physical activity: Group C. I. (high dynamic/low static) (n=12, mean age: 23.1?4.0 years, Group C. II. (high dynamic/moderate static) (n=22, mean age: 24.8?7.8 years) and Group C. III. (high dynamic/high static) (n=33, mean age: 23.0?6.1 years). Their results were compared to 83 age- and gender-matched non-athletic healthy controls (mean age: 23.6?3.2 years, 50 men). All athletes and non-athletes underwent a complete two-dimensional Doppler echocardiography examination with 3DSTE. Results None of the healthy subjects or athletes had any known cardiovascular risk factors or received drugs and ECG showed no significant alterations. Athletes spent 10.8?3.3 years, 10.1?5.9 years and 6.9?4.2 years in elite sport in Groups C. I., C. II. and C. III., respectively. No significant differences could be seen in the ratio of athletes being in an actual race period between Groups C. I., C. II. and C. III. [n=3 (25%), n=11 (50%) and n=11 (32%), respectively]. Enlarged LV dimensions and thickened posterior wall and interventricular septum were found in all athletes compared to the non-athlete healthy control group by 2-dimensional echocardiography. Increased 3DSTE-derived LV end-diastolic and end-systolic volumes could be seen in all athletes, the largest values were seen in the C. III. group. Global LV-LS (?18.5?3.0% vs. ?16.3?2.3%, p<0.05), LV-CS (?29.9?5.2% vs. ?28.1?4.8%, p<0.05) and LV-AS (?43.7?5.4% vs. ?40.9?4.8%, p<0.05) were increased as compared to those of non-athlete controls. All apical regional LV strains proved to be increased in all athletes with enhanced basal LS and midventricular LS, AS and 3DS. Global LV strains did not differ between the athlete groups based on static component of their training. No significant regional differences in LV strains could be detected between C. I., C. II. and C. III. groups (except in midventricular LV-LS). Conclusions Enhanced LV contractility represented by LV strains in longitudinal and circumferential directions could be demonstrated in elite athletes doing high dynamic sports, which does not depend on the grade of the static component of their training.
