Abstract

Aim. This paper aims to evaluate the ranges of left ventricular morphological remodeling in high-level athletes with different training and competition loads. Materials and methods. A single-center retrospective study was conducted, containing the results of 12,977 in-depth medical examinations from 6,481 national team athletes of both sexes across 20 sports, divided into groups according to the classification of Pelliccia et al. The groups were compared based on the following echocardiographic parameters: left ventricular end-diastolic volume index (LVEDVi), left ventricular end-systolic volume index (LVESVi), left ventricular end-diastolic diameter index (LVEDDi), left ventricular end-systolic diameter index (LVESDi), stroke index (SI), and left ventricular mass index (LVMI). Results. The comparative analysis demonstrated no statistically significant intergroup differences in LVEDDi or LVESDi. More pronounced, statistically significant differences were observed for volumetric parameters (LVEDVi, LVESVi) and stroke index (SI). However, the groups lacked uniformity; the range of medians and significant variations in interquartile ranges within each group reflected insufficient homogeneity among sports within the same category. LVMI showed statistically and clinically significant differences between the groups. Statistically significant differences in all parameters were identified when comparing skill-based sports with endurance sports. Results were similar for athletes of both sexes. Conclusion. The results reveal a certain insufficiency of the Pelliccia et al. classification, irrespective of athlete sex. The validity of using the studied parameters in isolation to group sports is therefore questioned.
