Key result
Endurance training in male athletes is linked to ~59% higher aortic distensibility vs. controls.
Why the study?
Aortic elastic properties are important determinants of left ventricular function, but their relationship with diastolic function in endurance athletes was not well defined.
Does endurance training improve aortic distensibility and left ventricular diastolic function in healthy males?
Comparison
Endurance athletes vs age-matched healthy controls
Design
Cross-sectional study with echocardiographic and cardiopulmonary exercise testing

May support vascular adaptation in male endurance athletes; leaves open causality and clinical relevance pending prospective data.

Does endurance training improve aortic distensibility and left ventricular diastolic function in healthy males?
Absolute Event Rate: 5.37% vs 3.37%
p-value: p=< 0.001
Endurance training is associated with increased aortic distensibility, which strongly correlates with improved left ventricular diastolic function as a physiological adaptation.
Kayserilioğlu et al. (2005) conducted a cross-sectional in Healthy endurance athletes (n=60). Endurance training vs. Age-matched healthy male controls was evaluated on Aortic distensibility index (p=< 0.001). Endurance training in male athletes was associated with a significantly higher aortic distensibility index compared to healthy controls (5.37 vs. 3.37 cm2.dynes-1.10-6, p < 0.001).
