Interpreting Youth Aerobic Fitness: Promoting Evidence-Based Discussion–A Response to Dotan (2019).

The authors convey their response to a feedback about their report on evidence-based discussion of the development of youth aerobic fitness. Topics mentioned include the principal reason that ratio scaling is still used to control for body mass in most publications, the credibility and simplicity of allometric scaling of cross-sectional data with multiple covariates based in log-linear regression, and the pitfalls of ratio scaling for a single anthropometric variable in cross-sectional data.
