Physiological assessment of left ventricular size indexed by peak oxygen uptake across sporting disciplines.

ABSTRACT:

Aims

Left ventricular (LV) enlargement is a common training-induced adaptation in athletes, particularly in endurance sports. Previous research indicates that indexing LV volumes and mass to absolute peak oxygen uptake (VO₂_peak) better reflects physiological adaptation than traditional indexing to body surface area (BSA). Therefore, we investigated whether indexing LV end-diastolic volume (LVEDV) and mass to VO_2peak could eliminate differences in LV size among athletes from different sport categories (endurance, mixed, power, and technical).

Methods and results

This analysis included 70 athletes from the multicenter COSMO-S in Germany and 15 elite endurance athletes from Norway. All participants (29 ± 8 years, 52 male) underwent echocardiography and car
