  • *≥130 and/or ≥90 mm Hg corresponds to the threshold defining hypertension in the current US guidelines, while ≥140 and/or ≥90 mm Hg correspond to current European guidelines.

  • †Data on ethnicity were missing for one of the athletes in the <120/<80 mm Hg group.

  • ‡Sphericity index was determined as (left ventricular (LV) length in the apical 4-chamber view/LV diameter in short-axis view).

  • ANOVA, analysis of variance; BMI, body mass index; BSA, body surface area; LVM, LVMI and LVEDV, LVEDVI, left ventricular mass and end-diastolic volume with and without indexing for BSA, respectively; MVR, LV mass/volume ratio; RWT, relative wall thickness; LVEF, left ventricular ejection fraction; LS4Ch, longitudinal strain (4-chamber view); E/A, early and late diastolic mitral inflow velocities; e’lateral, early diastolic velocity of the basal lateral left ventricular wall.
