The repeatability of functional traits like physiological maxima (maximum performance) measures the reliability of underlying measurements. However, best practices for analyzing maximal performance while accounting for within-individual variation are lacking. Here, we quantify the coefficient of variation and repeatability of maximum sprinting speed in common wall lizards (Podarcis muralis) from Cincinnati, USA. We use insights from experimental data and bootstrap resampling to discuss strategies for analyzing physiological maxima while accounting for within-individual variation. Relative to assuming greater among- than within-individual variation, the proposals exhibit greater precision in parameter estimates and statistical test results, with increased power. https://doi.org/10.32942/X29W8D Animal Sciences, Comparative and Evolutionary Physiology, Integrative Biology, Other Ecology and Evolutionary Biology, Zoology urban, introduced, intraspecific, ectotherm, velocity, invasive Published: 2026-02-17 06:54 Last Updated: 2026-02-17 07:03 CC-BY Attribution-NonCommercial 4.0 International Data and Code Availability Statement: Data and code will be made available through a permanent repository at time of publication.
