We aimed to clarify the myocardial adaptation to short-term high-intensity exercise among trained athletes. We screened 17 participants in the 2004 World Indoor Rowing Championships before and after a 2000-m sprint. Echocardiography included standard measurements and tissue Doppler-derived strain (epsilon), strain rate, and 2-dimensionally derived speckle-tracking imaging for left ventricular (LV) torsion. LV volumes and ejection fraction were unchanged after exercise. There was a reduction in early and an increase in late diastolic filling velocities and a decrease in the flow propagation velocity. Annular systolic velocities, slope of the systolic acceleration, septal and lateral epsilon, and speckle tracking-derived torsion were increased. The increased LV torsion was a result of increased basal and apical rotation. Right ventricular apical epsilon decreased. In conclusion, maximal intensity short-duration exercise was associated with attenuation of LV diastolic function, augmentation of LV systolic function, and a reduction in apical right ventricular contractility.
