Left ventricular long-axis diastolic function is augmented in the hearts of endurance-trained compared with strength-trained athletes
Key result
Endurance-trained athletes demonstrated augmented resting global diastolic function (E/A ratio 1.62 vs 1.18; P<0.01) and long-axis diastolic velocities compared with strength-trained athletes.
Why the study?
Does endurance training compared to strength training improve left ventricular functional reserve in athletes with left ventricular hypertrophy?
Population

Endurance training is associated with augmented left ventricular long-axis diastolic function and greater functional reserve compared to strength training in athletes with left ventricular hypertrophy.
Cite This Study
Vinereanu et al. (2002) conducted a cross-sectional in Left ventricular hypertrophy in athletes (n=43). Endurance training vs. Strength training was evaluated on Resting global diastolic function (E/A ratio) (p=<0.01). Endurance-trained athletes demonstrated augmented resting global diastolic function (E/A ratio 1.62 vs 1.18; P<0.01) and long-axis diastolic velocities compared with strength-trained athletes.
