Adaptation of left ventricular twist mechanics in exercise-trained children is only evident after the adolescent growth spurt

The extent of structural cardiac remodelling in response to endurance training is maturity dependent. In adults, this structural adaptation is often associated with the adaptation of left ventricular (LV) twist mechanics. For example, an increase in LV twist often follows an expansion in end-diastolic volume, whereas a reduction in twist may follow a thickening of the LV walls. Whilst structural cardiac remodelling has been shown to be more prominent post-peak height velocity (PHV), it remains to be determined how this maturation-dependent structural remodelling influences LV twist.
