May reflect physiologic remodeling in elite cyclists; leaves open functional consequences and causality in cross-sectional data.
Does professional road race cycling alter cardiac dimensions and left ventricular function compared to a sedentary lifestyle?
Professional cycling is associated with significant structural cardiac adaptations, including increased left ventricular dimensions and mass, which correlate with maximal oxygen consumption.
Bekaert et al. (1981) studied this question.
