Table 3.

Multiple linear regression results for predicting ΔePLAR from athlete status, METS (metabolic equivalents), age, BSA (body surface area), ΔsBP (systolic blood pressure), HR_max (maximum heart rate) and ΔCO (cardiac output). Only athlete status and METS (negative effect) significantly influenced ΔePLAR.
