Key result
Endurance training is linked to higher biventricular E/A and Em/Am ratios alongside stable LVMI/RVMI.
Why the study?
Findings on left ventricular function in athletes are controversial and studies on right ventricular adaptation to endurance training are limited.
Does endurance training improve left and right ventricular systolic and diastolic function in young athletes?
Population
60 endurance athletes and 60 healthy untrained subjects, mean age ~21 years
Comparison
Endurance training (athletes) vs no endurance training (untrained subjects)
Design
Cross-sectional study with echocardiography and tissue Doppler imaging

Endurance training improves biventricular systolic and diastolic function in young athletes; hypothesis-generating for broader populations and longitudinal effects.
Cross-Sectional (n=120)
Does endurance training improve left and right ventricular systolic and diastolic function in young athletes?
Absolute Event Rate: 3.77% vs 3.4%
p-value: p=0.5
Endurance training in young athletes induces balanced biventricular hypertrophy and improves both systolic and diastolic function.
Koç et al. (2007) conducted a cross-sectional in Endurance training adaptation (n=120). Endurance training vs. Untrained healthy subjects was evaluated on LVMI/RVMI ratio (p=0.5). Endurance training in young athletes was associated with significantly higher E/A and Em/Am ratios and Sm velocities of both ventricles (P<0.001) while maintaining a stable LVMI/RVMI ratio.
