Key result
Endurance training fails to alter peak early rapid filling LV wall motion vs sedentary controls.
Why the study?
Assessment of LV wall motion may provide additional information about LV diastolic function in endurance-trained athletes with physiologically hypertrophied hearts.
Does endurance training alter left ventricular wall motion during diastolic filling in physiologically hypertrophied hearts?
Population
30 endurance-trained athletes and 16 sedentary healthy controls
Comparison
Endurance-trained athletes vs sedentary controls
Design
Cross-sectional study using tissue Doppler and M-mode echocardiography

Supports preserved early diastolic motion in athlete hearts; hypothesis-generating for atrial differences and requires longitudinal validation.

Does endurance training alter left ventricular wall motion during diastolic filling in physiologically hypertrophied hearts?
Absolute Event Rate: 10.69% vs 10.61%
Endurance training induces physiological hypertrophy with increased LV mass and volume, but does not impair regional wall motion during the early rapid filling phase.
Schmidt‐Trucksäss et al. (2001) conducted a cross-sectional in Healthy (n=46). Endurance training vs. Sedentary lifestyle was evaluated on Peak LV wall motion during the early rapid filling phase. Endurance training did not significantly alter peak left ventricular wall motion during the early rapid filling phase compared to sedentary controls (10.69 vs 10.61 cm/s).
