Isolated left ventricular non-compaction (LVNC) has usually been viewed as a rare cardiomyopathy in athletes.

The aim of this study was to establish the degree of structural and functional adaptations in the left (LA) and right atria (RA) in elite male athletes engaged in ‘high dynamic : high static’ (HDHS) and ‘low dynamic : high static’ (LDHS) sporting disciplines compared with sedentary controls.

The individual response to acute and chronic changes in cardiac structure and function to intense exercise training is not fully understood and therefore evidence in this setting may help to improve the timing and interpretation of pre-participation cardiac screening.
