Key result
Relationships between body size variables and cardiac dimensions in junior athletes were non-linear, demonstrating that allometric scaling should be adopted over simple ratio scaling.
Cross-Sectional (n=464)
Allometric scaling, rather than simple ratio scaling, should be adopted to produce body-size-independent cardiac indices in junior athletes.
No takes yet. Share an insight, caveat, or question.
May support allometric scaling for cardiac indices in junior athletes; leaves open prospective validation before practice change.
George et al. (2000) conducted a cross-sectional in Elite 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. Relationships between body size variables and cardiac dimensions in junior athletes were non-linear, demonstrating that allometric scaling should be adopted over simple ratio scaling.
