| Popis: | Background: The speckle tracking echocardiography is a powerful tool that is expanding knowledge on cardiovascular physiology. At present fitness is an increasing sport, and the bench press is a typical exercise. The aim of this study was to investigate by speckle tracking echocardiography the systolic and diastolic properties of the left ventricle during bench press. Methods: Interventional study. We perform an echocardiogram before, during and immediately after a bench press. During the bench press we assessed the changes suffered in systolic and diastolic functions. Speckle tracking parameter and 3D volume were calculated for left ventricle. Results: In the study were included 59 male athletes with mean age 34.28 ± 9.54 years. Left ventricle ejection fraction is increased by 2D and 3D echocardiography (0.58 ± 0.07 versus 0.62 ± 0.07, p=0.017). The strain, strain rate, and systolic and diastolic velocities of longitudinal left ventricular fibers (by Speckle Tracking) are higher during exercise [(Strain -21.1 ± 4.09 versus -27.28 ± 3.73, p |
