  1. Results expressed as the mean ± standard deviation of 10 rats per group.
  2. B: balanced; BF: balanced/fructose; LB: low protein/balanced; LF: low protein/fructose.
  3. R: at rest; E: after acute physical exercise.
  4. Different letters indicate significant difference among groups (a#b). Two-Way ANOVA and Newman-Keuls’ Post-Hoc (p < 0.05).
  5. *intra-group difference by Student’s t-test (at rest vs. acute physical exercise).
