Abstract

Aims
This study aimed to evaluate left ventricular structure, function and mechanics, in highly-trained, pre-adolescent soccer players compared with age- and sex-matched controls.

Design
The study design was a prospective, cross-sectional comparison of left ventricular structure, function and mechanics.

Methods
Twenty-two male soccer players from two professional youth soccer academies (age: 12.00.3 years) and 22 recreationally active controls (age: 11.70.3 years) were recruited. Two-dimensional conventional and speckle tracking echocardiography were used to quantify left ventricular structure, function and peak/temporal values for left ventricular strain and twist, respectively.

Results
End-diastolic volume index was larger in soccer players (518mm/(m2)1.5 vs. 456 mm/(m2)1.5; p¼0.007) and concentricity was lower in soccer players (4.30.7 g/(mL)0.667 vs. 4.91.0g/(mL)0.667; p¼0.017), without differences in mean wall thickness between groups (6.00.4mm vs. 6.10.5 mm; p¼0.754). Peak circumferential strain at the base (–22.2%2.5% vs. –20.5%2.5%; p¼0.029) and papillary muscle levels (–20.1%1.5% vs. –18.3%2.5%;
p¼0.007) were greater in soccer players. Peak left ventricular twist was larger in soccer players (16.92 7.55 vs. 12.34 4.99; p¼0.035) and longitudinal early diastolic strain rate was greater in soccer players (2.220.40 s–1 vs.2.020.46 s–1; p¼0.025).

Conclusions
Highly-trained soccer players demonstrated augmented cardiac mechanics with greater circumferential strains, twist and faster diastolic lengthening in the absence of differences in wall thickness between soccer players and controls.
