Fig. 4. Relationship between body mass and metabolic rates (A) and between
wheel-running activity and metabolic rates (B) at baseline (open symbols) and
workload (closed symbols) conditions in Workload animals. Triangles represent
the RMR and circles represent DEE. Regression lines for all relationships are
drawn. For equations of the regression lines, r2 and
P values, see Table 4.
Results of multiple regressions are presented in the text.
