Table 3 Key consideration points regarding body size for preparticipation screening

Indexing LVEDD and LV mass to FFM is optimal compared to BSA, body mass and height and in athletes displaying extreme anthropometry. Indexing to BSA with population-specific allometric b exponents, however, is also valid, and yields a greater ease of access

RV size is allometrically related to BSA when indexed with population-specific allometric b exponents. This may improve the efficacy in AVC identification in athletes who present with extreme anthropometry

LA diameter and height appear to have a significant linear relationship when ratiometric scaling is utilised. Lean body mass may be especially important in screening athletes with low body fat

Indexed aortic root dimensions have correlations with ratiometric scaling to height. As aortic root diameter values typically fall within established normal limits, indexed aortic reference values may be helpful in the early detection of aortic pathologies in athletes who exceed these limits
