  1. Values are reported as the mean ± standard deviation
  2. Relative tissue weight (%) = tissue weight (g)/final body weight (g) × 100%. ap < 0.05, b p < 0.01. Means with different superscripts in each row are significantly different from SC (one–way ANOVA followed by a Tukey’s post-hoc test)
  3. SC sedentary control, CMT continuous moderate-intensity training, HIIT high intensity interval training, BW body weight, EI the energy intake
