Key result
Body mass and body surface area showed non-linear relationships with cardiac dimensions (e.g., left ventricular mass to body mass slope exponent 0.91±0.11), supporting allometric scaling.
Cross-Sectional (n=464)
Allometric scaling, rather than simple ratio scaling, should be used to normalize echocardiographic cardiac dimensions for body size in junior athletes.

Supports allometric scaling for cardiac dimensions in junior athletes; hypothesis-generating and requires prospective validation.
George et al. (2001) conducted a cross-sectional in Healthy junior athletes (n=464). Body size variables (body mass, height, body surface area) was evaluated on Slope exponent (b) for relationships between body size variables and cardiac dimensions. Body mass and body surface area showed non-linear relationships with cardiac dimensions (e.g., left ventricular mass to body mass slope exponent 0.91±0.11), supporting allometric scaling.
