Multiple regressions showed that at baseline RMR and DEE were better predicted by body mass alone, and at workload by wheel-running activity alone. Results of multiple regressions with both body mass and wheel-running activity as independent predictors of RMR or DEE are described in the text. See also Fig. 4
